Question 1

Sliding door lock and catch failure (Transporter T6)

Accepted Answer

The sliding side door locks and catches on the Transporter T6 wear out, so the door won't open, close or lock properly. Central locking faults on the sliding door are common on high-mileage vans.

Question 2

AdBlue (SCR) system faults (2.0 TDI)

Accepted Answer

The SCR emissions system on the 2.0 TDI can develop faults in the AdBlue pump, tank heater, NOx sensors or dosing injector, often caused by crystallised fluid. The dashboard shows an emissions warning and a countdown in miles after which the engine will not restart.

Question 3

DPF blockage from short journeys (2.0 TDI)

Accepted Answer

The diesel particulate filter on the 2.0 TDI needs regular sustained runs at motorway speeds to regenerate. Cars used mainly for short urban trips light up the DPF warning, lose power and may go into limp mode; repeated interrupted regenerations also dilute the engine oil with diesel.

Question 4

EGR cooler coolant leak (2.0 TDI)

Accepted Answer

The EGR cooler on the 2.0 TDI can crack internally, so coolant is lost with no visible external leak. Symptoms include a slowly dropping coolant level, white smoke or a sweet smell from the exhaust and, in advanced cases, overheating. Some cars were covered by a manufacturer recall or extended warranty.
