Known Volkswagen Transporter faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01Timing Belt and Tensioner Failure (2.0 TDI)
CriticalOccasionalEngine $900–$14,000 to fix
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
Ask for documented timing belt replacement history with date and odometer reading. Inspect the belt service sticker inside the engine bay. At the service interval, physically inspect the belt for cracking, glazing, or contamination. Confirm the tensioner pulley and idler were replaced at the same time as the belt. 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)
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?”
02T4 2.5 TDI ageing leaks — injection pump seals, rear main and power steering
MinorVery commonFluid Leaks $400–$1,800 to fix
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
Ask the seller
“Has the injection pump ever been resealed?”
“Any hot-start problems?”

Should I get a pre-purchase inspection on a Volkswagen Transporter?
+
Yes. A Volkswagen Transporter inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
