Now narrow it to the engine

A 1.8 and a 2.4 of the same car do not fail the same way, so the faults below narrow to the engine as well as the year. Free, no account needed.

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

• Serious issue

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

  1.6 TDI Timing Belt Failure on Interference Engine

  The 1.6 TDI engine used in the 2K and SA Caddy is an interference engine with a rubber timing belt. When the belt snaps or skips, the pistons contact the open valves, causing immediate and total engine destruction. VW specifies belt replacement every 60,000 km or 4 years. Many used Caddies arrive in NZ/AU with overdue belts or no service history documenting the change. A neglected timing belt on this engine is the highest probability catastrophic failure for the model.

  What you would notice

  • No warning before failure — engine stops instantly when belt breaks
  • Overdue service interval (belt not replaced by 60,000 km / 4 years)
  • Belt tensioner noise — squealing from front of engine (pre-failure warning, rare)
  • Oil or coolant contamination on belt (accelerates degradation)

  Typically $700–$1,500 to put right.

• Serious issue

  Drive it in slow traffic, because open-road running flatters this gearbox completely.

  See why

  Dry seven-speed DSG jerking and clutch pack wear from around 80,000 km

  Caddys fitted with the dry-clutch seven-speed DSG develop a characteristic set of problems from around 80,000 km: jerking through the lower gears, changes that take far longer than they should, and in the worst cases a complete failure to engage. The causes are a worn clutch pack or a mechatronic unit that has given up. A dry-clutch DSG has no oil bath to carry heat away from the clutches, which is why a van used for stop-start delivery work suffers far more than one that does open-road runs — and vans do exactly the driving this gearbox likes least. The maintenance point matters: the fluid and filter want replacing every 60,000 km to protect the mechatronics, and a van with no record of that has been running the unit on degraded oil for its whole life.

  What you would notice

  • Jerking or snatching through first, second and third
  • Long pause between selecting a gear and the van moving
  • Shudder felt through the seat when pulling away
  • Burning smell after slow traffic or a hill start
  • Transmission warning message, or the gearbox refusing to engage at all

  Typically $900–$7,000 to put right.

• Serious issue

  Ask whether the oil pump and balance-shaft module have ever been upgraded or replaced - this is the single best question for this engine.

  See why

  2.0 TDI oil pump / balance shaft hex drive failure (PD and early common-rail)

  The 2.0 TDI in the earlier Caddy drives its oil pump off a balance-shaft module through a small hexagonal (6mm) shaft. VW's original design does not engage deeply enough, so the hex rounds off, the pump stops turning and oil pressure collapses - usually with almost no warning. If the driver keeps going, the engine spins its bearings and is destroyed. It is a well-documented VAG failure that can strike from around 120,000 km. Some engines were updated to a stronger 100mm drive, but even those can fail. On a van worked hard, this is the fault that turns a cheap buy into a scrap engine.

  What you would notice

  • Oil pressure warning light (often just before failure)
  • Sudden knocking from the bottom of the engine
  • Engine seizes or stalls and will not restart
  • Metal glitter in the oil / on the dipstick

  Typically $2,500–$8,000 to put right.

• Costly issue

  Get there before the van has been started, because cold starting is where this shows.

  See why

  TDI injector failure — hard starting and misfire from around 90,000 km

  Injector failure is one of the more commonly reported faults on the diesel Caddy, showing up from roughly 90,000 km and most often on the higher-output variants. It presents as difficulty starting, a misfire that makes the van shake at idle, rough running and more smoke than there should be under load. Diesel injectors are precision parts working at very high pressure and they are punished by poor fuel and by a fuel filter left in too long — both far more likely on a working van doing short trips and long days than on a private car. Owners adapt to the symptoms without noticing, so a van that "always needs a couple of goes on a cold morning" is describing this. Injectors are usually done as a set, which is what makes the bill matter.

  What you would notice

  • Hard starting, or needing to crank for several seconds from cold
  • Misfire making the van shake or vibrate at idle
  • More smoke than usual under load, grey, black or white
  • Rough or uneven running, especially before it warms up
  • Engine warning light with fuel-system codes

  Typically $800–$3,500 to put right.

• Costly issue

  Ask what the van was used for - courier and multi-drop city work is the red flag.

  See why

  DPF clogging and EGR fouling from stop-start van use (1.6/2.0 TDI)

  The Caddy 2K is a working van, and most spend their lives doing short urban delivery hops. The 1.6 and 2.0 TDI diesels have a diesel particulate filter (DPF) that only cleans itself (regenerates) on longer, hotter runs. Trades vans that never get a proper motorway drive block the DPF with soot, and the EGR valve carbons up alongside it. Once blocked you get limp mode, warning lights and a forced-regen or replacement bill. Ignored, a fully blocked DPF must be replaced. This is the single most common reason a cheap ex-fleet Caddy is being sold.

  What you would notice

  • Glow-plug or DPF warning light on the dash
  • Loss of power / limp mode
  • Puffs of black or white smoke
  • Strong diesel smell and radiator fan running hard after a short trip
  • Rough idle or hesitation

  Typically $500–$3,500 to put right.

• Costly issue

  Be there for a cold start and sit with it as it idles, because a clogged injector is at its worst then.

  See why

  1.5 TSI direct injector clogging — rough idle and hesitation

  The direct injectors on the 1.5 TSI clog over time, and poor-quality fuel accelerates it markedly. It shows as a rough idle, hesitation when you accelerate, fuel economy that has quietly worsened, and eventually misfires. Direct injection sprays fuel straight into the cylinder at very high pressure through a very small nozzle, which is why deposits matter more here than on an older port-injected engine — a partially blocked nozzle sprays a poor pattern rather than simply flowing less. On a working van the fuel comes from wherever is convenient, which is part of why this shows up. It is a cleaning or replacement job rather than a mechanical failure, so the value in identifying it is knowing you are not looking at something worse.

  What you would notice

  • Rough or uneven idle, worst when cold
  • Hesitation or a stumble when accelerating
  • Fuel economy noticeably worse than it used to be
  • Misfire, or an engine warning light
  • Engine feeling flat at low revs

  Typically $500–$2,400 to put right.
