What to look out for

The checks worth doing on a Volkswagen Transporter before you hand over any money. Every documented fault is listed below, each with its own page.

  • Serious issue

    Magnet and torch around all arches, sills, jacking points and the sliding-door track.

    See why

    T4 rust — front arches, sills, sliding door track, seams and windscreen surround

    Every remaining T4 in NZ is 20+ years old and rust decides its fate: front wheel arches, sill seams, the sliding-door lower track, rear arches, seam rust along gutters and around the windscreen. Many are campers with rot hidden behind lining. Structural rust is a WOF failure and proper seam repairs are labour-heavy.

    What you would notice

    • Bubbling on arches and sills
    • Rust along roof gutters and seams
    • Crusty sliding-door track
    • Damp/rust under cab floor mats

    Typically $800–$6,000 to put right.

  • Serious issue

    Listen to the warm engine at idle for top-end tapping.

    See why

    T5 2.5 TDI (AXD/AXE/BNZ/BPC) — camshaft wear and oil pump hex-drive failure

    The T5's 2.5 five-cylinder is infamous for two engine-killers: soft camshafts/lifters that wear prematurely (tappet rattle, misfire, low power), and the balance-shaft/oil-pump hexagonal drive shaft rounding off — which instantly drops oil pressure and destroys the engine if the driver ignores the light. Preventive fixes (upgraded hex shaft, cam replacement) are well documented; an engine with no history of them is a gamble.

    What you would notice

    • Tappet/top-end rattle when warm
    • Oil pressure light flicker — stop immediately
    • Misfire or lack of power
    • Metal glitter in drained oil

    Typically $1,500–$8,000 to put right.

  • Serious issue

    Confirm the timing belt replacement date and mileage from service records.

    See why

    T5 2.0 TDI timing belt and plastic idler pulley failure

    The T5 Transporter's 2.0 TDI diesel uses a rubber timing belt driving an interference engine. The plastic idler and tensioner pulleys are prone to cracking and seizure, causing sudden belt failure with no warning. This is widely documented in the Australian and NZ camper van and commercial communities. Belt failure causes piston-to-valve contact and total engine destruction. Manufacturer service interval is 100,000 km but independent workshops recommend 80,000 km or 4 years given pulley brittleness.

    What you would notice

    • No audible warning before failure – belt snaps suddenly
    • Engine cuts out without warning while driving
    • If caught early, rattling or squealing from the belt area indicates tensioner wear
    • Visible cracking on idler pulley plastic body on inspection

    Typically $700–$1,400 to put right.

  • Serious issue

    Ask for documented timing belt replacement history with date and odometer reading.

    See why

    Timing Belt and Tensioner Failure (2.0 TDI)

    Unlike many modern diesel engines, the 2.0 TDI (EA288) in the T6 Transporter uses a rubber timing belt — not a chain — driving both the camshaft and the high-pressure fuel injection pump. The belt tensioner and water-pump drive tensioner are failure points: a seized or failed tensioner can cause belt skip or snap at any speed, resulting in catastrophic piston-to-valve contact and complete engine destruction. VW specifies a 210,000 km or 4-year interval, but many workshops and VW NZ dealers recommend earlier replacement under commercial-use conditions.

    What you would notice

    • Sudden complete engine failure with loud mechanical bang or rapid shutdown
    • Engine cranks but will not start (belt has skipped or snapped)
    • Metallic ticking or rattling from the timing cover area at startup
    • Coolant leak from the water pump area (shared timing belt drive, failure may be linked)
    • No prior warning in most cases — failure is sudden and catastrophic

    Typically $900–$14,000 to put right.

  • Serious issue

    Cold-check coolant colour/level and look for oil film; hot-check for over-pressurisation after a hard drive.

    See why

    T5.1 2.0 BiTDI (CFCA) — same EGR cooler/head risks and high oil consumption

    Facelift T5.1s replaced the 2.5 with 2.0 common-rail engines; the 132 kW twin-turbo CFCA carries the same reputation as in the Amarok — EGR cooler corrosion, coolant loss, head gasket failures and heavy oil consumption, with documented engine failures in UK/AU fleets. The single-turbo 62/75/103 kW versions are notably more reliable. Check any BiTDI's cooling system forensically.

    What you would notice

    • Coolant loss without visible leak
    • High oil consumption
    • White smoke on start
    • Overheating under load

    Typically $1,500–$9,000 to put right.

  • Costly issue

    Check for DPF warning light or regeneration light on the dashboard.

    See why

    DPF Blockage from Urban / Short-Trip Use

    The 2.0 TDI engines require sustained highway driving (typically 20+ minutes at >2500 rpm) to complete a passive or active DPF regeneration cycle. Urban delivery and trade use — the dominant T6 use case — prevents regeneration, causing soot accumulation until the filter is fully blocked. Forced active regeneration by a dealer can restore function if caught early, but badly blocked filters require replacement, and repeated blockage destroys the unit.

    What you would notice

    • DPF warning light or glow-plug light flashing on dashboard
    • Engine entering limp mode with reduced power above ~2500 rpm
    • Strong diesel/fuel smell from exhaust at idle during forced regen attempt
    • Increased engine oil level due to diesel dilution from failed regens
    • Excessive black smoke from exhaust under load

    Typically $800–$3,200 to put right.

01Timing Belt and Tensioner Failure (2.0 TDI)

Ask for documented timing belt replacement history with date and odometer reading.diesel2015–2023Engine
OccasionalEngine $900–$14,000 to fix

Can't confirm for this car

Unlike many modern diesel engines, the 2.0 TDI (EA288) in the T6 Transporter uses a rubber timing belt — not a chain — driving both the camshaft and the high-pressure fuel injection pump. The belt tensioner and water-pump drive tensioner are failure points: a seized or failed tensioner can cause belt skip or snap at any speed, resulting in catastrophic piston-to-valve contact and complete engine destruction. VW specifies a 210,000 km or 4-year interval, but many workshops and VW NZ dealers recommend earlier replacement under commercial-use conditions.

Symptoms to notice

  • Sudden complete engine failure with loud mechanical bang or rapid shutdown
  • Engine cranks but will not start (belt has skipped or snapped)
  • Metallic ticking or rattling from the timing cover area at startup
  • Coolant leak from the water pump area (shared timing belt drive, failure may be linked)
  • No prior warning in most cases — failure is sudden and catastrophic

What to check

  1. Ask for documented timing belt replacement history with date and odometer reading.
  2. Inspect the belt service sticker inside the engine bay.
  3. At the service interval, physically inspect the belt for cracking, glazing, or contamination.
  4. Confirm the tensioner pulley and idler were replaced at the same time as the belt.
  5. High-mileage commercial vans with no service record are high risk.

Where to look: Front of engine, behind the timing cover on the accessory-belt side (right side when facing engine bay)

Parts involved: Timing belt.

Ask the seller

  • “Can you provide a stamped invoice confirming when the timing belt, tensioner, and idler were last replaced?”
  • “What is the current mileage, and was the belt replaced on schedule according to VW's interval?”
  • “Was the water pump also replaced at the last timing belt service?”

02T5.1 2.0 BiTDI (CFCA) — same EGR cooler/head risks and high oil consumption

Cold-check coolant colour/level and look for oil film; hot-check for over-pressurisation after a hard drive.diesel2010–2015Engine
OccasionalEngine $1,500–$9,000 to fix

Can't confirm for this car

Facelift T5.1s replaced the 2.5 with 2.0 common-rail engines; the 132 kW twin-turbo CFCA carries the same reputation as in the Amarok — EGR cooler corrosion, coolant loss, head gasket failures and heavy oil consumption, with documented engine failures in UK/AU fleets. The single-turbo 62/75/103 kW versions are notably more reliable. Check any BiTDI's cooling system forensically.

Symptoms to notice

  • Coolant loss without visible leak
  • High oil consumption
  • White smoke on start
  • Overheating under load

What to check

Cold-check coolant colour/level and look for oil film; hot-check for over-pressurisation after a hard drive. Dipstick history: ask how much oil it uses. Prefer invoices showing EGR cooler or head work already done — or buy the single-turbo engine instead.

Where to look: EGR cooler and head on the engine; symptoms at the coolant tank

Parts involved: EGR valve.

Ask the seller

  • “How much oil does it use?”
  • “Ever lost coolant or overheated?”
  • “EGR cooler or head gasket ever replaced?”

05Fuel Injector Tip Failure and Diesel Dilution of Engine Oil

Pull the oil dipstick and smell the oil for diesel fuel odour — diluted oil will also show above the maximum mark.diesel2015–2023Engine
OccasionalEngine $1,800–$5,500 to fix

Can't confirm for this car

The common-rail piezoelectric injectors used in EA288 2.0 TDI engines (CXHA, DABB codes) are known to develop tip seal failures, allowing a fine mist of diesel to bypass the combustion event and drain into the sump via the cylinder walls. This progressively dilutes the engine oil with diesel fuel, reducing lubrication effectiveness and accelerating bearing wear. In severe cases an injector tip can physically separate inside the combustion chamber. The condition is insidious because fuel-diluted oil still appears dark and normal during a cursory check.

Symptoms to notice

  • Engine oil level rising above the maximum mark with no external oil added
  • Diesel fuel smell from the engine oil on the dipstick
  • Rough idle or single-cylinder misfire with associated fault code
  • Excessive white or blue smoke on cold start that does not clear
  • Increased fuel consumption with no change in driving pattern

What to check

  1. Pull the oil dipstick and smell the oil for diesel fuel odour — diluted oil will also show above the maximum mark.
  2. Check the oil filler cap interior for frothy or milky deposits.
  3. Scan for injector return flow fault codes and compression imbalance between cylinders.
  4. If a workshop inspection is possible: If possible, have an independent workshop perform a relative compression test or leak-back test on each injector.

Where to look: Top of engine — four injectors seated in the cylinder head, accessed from above after removing engine cover

Parts involved: Fuel injector.

Ask the seller

  • “Has the engine oil ever risen above the maximum level, and was the cause investigated?”
  • “Have any injectors been replaced under warranty or out of pocket, and can you show the invoice?”
  • “Does the engine produce blue or white smoke on cold start that takes more than a minute to clear?”

06DSG (DQ500) mechatronics and flywheel wear on hard-used vans

Stop-start test drive with hill starts; feel for shudder and check for instant, smooth engagement of D and R.diesel2015 onwardTransmission
OccasionalTransmission $2,000–$5,500 to fix

Can't confirm for this car

The T6's 7-speed wet-clutch DQ500 DSG is one of VW's stronger gearboxes, but high-mileage or hard-towing vans show mechatronic faults (gear warnings, harsh engagement, limp to one gearset) and clutch-pack/flywheel wear felt as shudder. Fluid changes every 60,000 km are essential and often skipped by fleets. Mechatronics repair or clutch packs are four-figure jobs.

Symptoms to notice

  • Shudder at take-off
  • Gearbox warning / flashing gear display
  • Harsh or delayed engagement
  • Limp mode with limited gears

What to check

Stop-start test drive with hill starts; feel for shudder and check for instant, smooth engagement of D and R. Verify DSG fluid/filter changes at 60,000 km intervals in the records.

Where to look: DSG transaxle on the engine's left; mechatronics inside the gearbox

Parts involved: Mechatronic / valve body.

Ask the seller

  • “When was the DSG fluid last changed?”
  • “Any gearbox warnings or warranty work?”

08Dual-mass flywheel failure (manual T5) and driveshaft/flex issues

Neutral idle listen, then press the clutch — a change in rattle implicates the DMF.diesel2004–2015Transmission
CommonTransmission $2,200–$3,500 to fix

Can't confirm for this car

Manual T5s chew dual-mass flywheels — rattle at idle, vibration and judder — with failure common by 150,000-200,000 km, sooner on heavily loaded vans. DMF plus clutch is a standard but pricey job. On 4Motion and high-mileage vans also check driveshaft joints and the propshaft centre bearing.

Symptoms to notice

  • Rattle at idle that changes with clutch pressed
  • Judder pulling away
  • Vibration at certain revs
  • Clonk on gear changes

What to check

  1. Neutral idle listen, then press the clutch — a change in rattle implicates the DMF.
  2. Feel for take-off judder on a hill start.
  3. Ask for the clutch/DMF replacement invoice and mileage.

Where to look: Flywheel between engine and gearbox

Parts involved: Clutch.

Ask the seller

  • “Has the DMF and clutch been replaced — when?”
  • “Does it rattle at idle?”

09T6 Euro 6 DPF and AdBlue system faults

Confirm no emissions warnings and no start-countdown active.diesel2016 onwardEngine
CommonEngine $400–$3,500 to fix

Can't confirm for this car

Euro 6 T6/T6.1 vans add AdBlue injection, and short-trip use brings DPF blockage plus AdBlue faults: crystallised injectors, failing NOx sensors and level-sensor errors, with limp mode or start-inhibit countdowns. Forum consensus rates Euro 6 vans as noticeably more troublesome than the earlier Euro 5s. Repairs range from a forced regen to four-figure DPF or sensor/pump jobs.

Symptoms to notice

  • DPF or AdBlue warning light
  • Start-countdown message
  • Limp mode
  • Excessive regens / hot smell

What to check

  1. Confirm no emissions warnings and no start-countdown active.
  2. Ask usage pattern and check AdBlue consumption seems normal.
  3. Scan soot/ash load if possible; check the oil isn't over-filled from regen dilution.

Where to look: DPF/SCR in the exhaust; AdBlue tank and injector under the van

Parts involved: Diesel particulate filter.

Ask the seller

  • “Any DPF or AdBlue faults or repairs?”
  • “Does it get regular open-road runs?”

11T6/T6.1 EGR valve and cooler carbon blockage

Scan for stored EGR codes pre-purchase.diesel2015 onwardEngine
CommonEngine $900–$2,800 to fix

Can't confirm for this car

The Euro 5/6 2.0 TDI T6 is known for EGR valve and cooler carbon build-up at higher mileages, causing warning lights, low power and poor economy; forum consensus is that Euro 6 vans (post-2016) suffer more than Euro 5. EGR replacement on these engines is a substantial labour job at NZ rates.

Symptoms to notice

  • Engine warning light
  • Low power / limp mode
  • Poor fuel economy
  • Rough idle

What to check

  1. Scan for stored EGR codes pre-purchase.
  2. Ask about the van's duty cycle — short-run city vans clog sooner.
  3. Confirm clean, strong acceleration with no hesitation on the test drive.

Where to look: EGR valve and cooler on the front/exhaust side of the engine

Parts involved: EGR valve.

Ask the seller

  • “Has the EGR ever been cleaned or replaced?”
  • “Any warning lights or limp mode events?”

12EGR valve and cooler failure causing intake manifold carbon buildup

Scan for EGR-related fault codes (P0400–P0409).diesel2003 onwardEngineRead the full fault: symptoms, where to look, what to ask the seller

13EGR Valve Carbon Sticking and Flow Failure

Scan for fault codes P0400, P0401, P0402, P0403 (EGR circuit and flow faults).diesel2015–2023Engine
CommonEngine $400–$1,400 to fix

Can't confirm for this car

The EGR valve on 2.0 TDI engines accumulates carbon deposits over time, eventually sticking partially or fully open or closed. A stuck-open EGR valve introduces excessive recirculated exhaust gas into the intake, causing power loss, rough running, and increased smoke. A stuck-closed valve triggers emissions fault codes and can result in failed WoF emissions testing in New Zealand. The issue is accelerated by low-quality diesel, short-trip urban use, and deferred air filter changes.

Symptoms to notice

  • Loss of power particularly at low rpm and partial throttle
  • Rough idle or lumpy running at operating temperature
  • Black smoke from exhaust under moderate acceleration
  • EGR or emissions fault code stored in ECU
  • Failed emissions test at WoF inspection due to elevated NOx or opacity

What to check

  1. Scan for fault codes P0400, P0401, P0402, P0403 (EGR circuit and flow faults).
  2. Inspect the EGR valve for carbon deposits by removing and examining the valve seat.
  3. Check intake manifold for heavy carbon fouling visible through the EGR port.
  4. Road-test for hesitation and puff of black or blue smoke on acceleration from low rpm.

Where to look: Top of engine, intake manifold side — a cylindrical valve unit with electrical connector and coolant hoses

Parts involved: EGR valve.

Ask the seller

  • “Has the EGR valve ever been cleaned or replaced, and is there a record of when?”
  • “Has the van ever had an EGR-related fault code or failed an emissions inspection?”
  • “Does the engine produce black smoke or hesitate under load at low speeds?”

01AdBlue SCR System — NOx Sensor and Pump Failure

Check the AdBlue tank is filled (minimum level warning should not be lit).diesel2019–2023Electrical
OccasionalElectrical $900–$2,800 to fix

Can't confirm for this car

T6.1 Transporters (2019-onwards) and some later T6 variants fitted with SCR (Selective Catalytic Reduction) AdBlue systems experience failures of the NOx sensors (upstream and downstream of the SCR catalyst) and the AdBlue dosing pump. Failed NOx sensors trigger fault codes and eventually place the engine in a start-count-down mode where, after a set number of ignition cycles, the vehicle will not restart until the fault is cleared. The dosing pump and injector also crystallise with dried AdBlue if the vehicle sits unused for extended periods.

Symptoms to notice

  • AdBlue warning light on dashboard with countdown to engine start restriction
  • Engine entering de-rate mode (power reduction) without fuel or mechanical fault
  • White crystalline deposits around AdBlue filler cap or dosing injector
  • Fault codes for NOx sensor implausible signal (P2201/P2202) stored in engine ECU
  • Engine will not restart after a set number of key cycles despite full AdBlue tank

What to check

  1. Check the AdBlue tank is filled (minimum level warning should not be lit).
  2. Scan for NOx sensor fault codes (P20EE, P2201, P2202) and dosing pump faults.
  3. Check for a countdown warning in the instrument cluster.
  4. Inspect around the AdBlue filler and tank for white crystalline residue indicating past leaks or spills.

Where to look: NOx sensors on exhaust system — one before and one after the SCR catalyst under the vehicle; AdBlue tank and pump in the engine bay or chassis rail

Parts involved: Fuel injector, Catalytic converter.

Ask the seller

  • “Has the AdBlue system ever shown a fault or countdown warning, and was the NOx sensor replaced?”
  • “Has the vehicle sat unused for more than a month, and was the AdBlue pump inspected afterward?”
  • “Is there any history of AdBlue leaks or crystalline residue around the dosing system?”

01T4 rust — front arches, sills, sliding door track, seams and windscreen surround

Magnet and torch around all arches, sills, jacking points and the sliding-door track.diesel2000–2003Body & Rust
Very commonBody & Rust $800–$6,000 to fix

Can't confirm for this car

Every remaining T4 in NZ is 20+ years old and rust decides its fate: front wheel arches, sill seams, the sliding-door lower track, rear arches, seam rust along gutters and around the windscreen. Many are campers with rot hidden behind lining. Structural rust is a WOF failure and proper seam repairs are labour-heavy.

Symptoms to notice

  • Bubbling on arches and sills
  • Rust along roof gutters and seams
  • Crusty sliding-door track
  • Damp/rust under cab floor mats

What to check

Magnet and torch around all arches, sills, jacking points and the sliding-door track. Lift cab carpets and check the floor and seatbelt anchor areas. In campers, inspect behind furniture wherever panels lift. Check the windscreen surround for bubbling under the trim.

Where to look: Front/rear arches, sills, sliding-door track, roof gutters, windscreen surround, cab floor

Parts involved: Chassis and structural rust, Body corrosion.

Ask the seller

  • “What rust repairs have been done for past WOFs?”
  • “Can I lift the floor coverings?”

02T4 nose-heavy front suspension wear — ball joints, wishbone bushes, springs

Rock each front wheel at 12-6 and 9-3 for play, check tyre wear pattern, and look at front spring condition and ride height.diesel2000–2003Suspension
Very commonSuspension $400–$1,500 to fix

Can't confirm for this car

The T4 carries its engine over the front axle and eats front suspension: lower ball joints, wishbone bushes, drop links and sagging/cracked front springs. Symptoms are clunks, wander and inside-edge tyre wear. Parts are cheap and available; it's the labour and the WOF failures that catch buyers out.

Symptoms to notice

  • Clunks over bumps
  • Vague, wandering steering
  • Inside-edge front tyre wear
  • Front sitting low

What to check

Rock each front wheel at 12-6 and 9-3 for play, check tyre wear pattern, and look at front spring condition and ride height. Bounce each corner for tired dampers.

Where to look: Front lower arms, ball joints, springs and dampers

Parts involved: Ball joint.

Ask the seller

  • “What front-end parts have been replaced recently?”
  • “When did it last have a wheel alignment?”

03Sliding Door Roller and Track Wear

Open and close the sliding door fully several times — listen for grinding, clicking, or scraping.2015–2023Body & Rust
CommonBody & Rust $300–$1,200 to fix

Can't confirm for this car

The T6 Transporter's sliding door system uses an upper, centre, and lower roller assembly running in aluminium tracks. Under commercial use — particularly with heavy loads passing through the door opening repeatedly — the plastic roller carriages crack, the bearings seize, and the lower track accumulates debris causing the door to drop, drag, or jump off the track. The lower striker and latch mechanism also wear, leading to doors that do not fully latch on the first closure. This is a recognised pattern across both passenger-configured and panel van T6 bodies.

Symptoms to notice

  • Sliding door difficult to open or close, requiring excessive force
  • Grinding or clicking noise throughout door travel
  • Door visibly dropping at the rear edge when partially open
  • Door failing to latch securely on the first push
  • Visible damage or deformation to the lower sill track

What to check

  1. Open and close the sliding door fully several times — listen for grinding, clicking, or scraping.
  2. Check that the door sits flush when closed with no visible gap at the top or bottom.
  3. Physically inspect each roller carriage for cracked plastic housings or seized bearings.
  4. Check the lower sill track for crushed or deformed sections.
  5. Test the latch by pushing the closed door inward — it should have no movement.

Where to look: Sliding door — upper track at roof line, centre track at waist level, lower track at sill; inspect all three roller carriages

Ask the seller

  • “Has the sliding door ever been adjusted, had rollers replaced, or had the track repaired?”
  • “Does the door latch securely every time without needing a second push?”
  • “Has the van been used for trade or delivery work with frequent high-load access through the side door?”
Fluid leaks1

01T4 2.5 TDI ageing leaks — injection pump seals, rear main and power steering

Torch over the injection pump (front of engine) for wet diesel staining.diesel2000–2003Fluid Leaks
Very commonFluid Leaks $400–$1,800 to fix

Can't confirm for this car

The T4's 2.5 TDI (ACV/AXG) is fundamentally tough, but at 20+ years the Bosch injection pump head seals, crank seals and power steering hoses all weep. A leaking pump seal causes diesel smell, hard hot-starts and eventually fuel starvation. All fixable at sensible cost, but budget for a reseal on any un-restored van.

Symptoms to notice

  • Diesel smell and wet pump body
  • Hard starting when hot
  • Oil drips at bellhousing
  • PAS fluid weeps at hoses

What to check

Torch over the injection pump (front of engine) for wet diesel staining. Do a hot-restart test after the drive. Check the ground under engine/gearbox and PAS reservoir level.

Where to look: Injection pump front of engine; crank seals at bellhousing; PAS lines

Parts involved: High-pressure fuel pump, Steering rack.

Ask the seller

  • “Has the injection pump ever been resealed?”
  • “Any hot-start problems?”
