Problem 1
Volkswagen Transporter: EGR valve or EGR cooler failure
What goes wrong
The EGR valve sticks with soot and the EGR cooler can crack and leak coolant into the exhaust.
How to check it yourself
Read EGR codes and compare actual and requested EGR position in live data. Unexplained coolant loss with white smoke points to the EGR cooler; have it pressure-tested.
The usual fix
Replace the EGR valve; replace a leaking EGR cooler. Ask a VW dealer whether goodwill or a campaign applies, as this fault is well known.
Signs: Loss of power, Check engine light, Coolant loss, White smoke
Fault codes: P0401, P0402, P0403, P0404
Problem 2
Volkswagen Transporter: Worn dual-mass flywheel: rattle and judder
What goes wrong
The dual-mass flywheel between engine and clutch wears out, especially under heavy loads or towing.
How to check it yourself
Listen for a rattle at idle that goes away when you press the clutch, and a knock when switching the engine off. A garage can measure the flywheel’s free play through the starter opening.
The usual fix
Replace the flywheel together with the clutch kit. Caught early, it’s far cheaper than after the flywheel breaks up.
Signs: Rough idle, Clutch slipping
Problem 3
Volkswagen Transporter: Knocking from worn bushes or a broken coil spring
What goes wrong
Suspension bushes wear and rear coil springs are known to break, especially on loaded vans.
How to check it yourself
Look at the rear springs for a broken end coil and check whether the van sits lower on one side; check wishbone and anti-roll-bar bushes for splits.
The usual fix
Replace broken springs in pairs and replace worn bushes or drop links.
Signs: Clunk over bumps
