What to watch for

What can go wrong on this car?

The list covers the generation, the engines and the transmissions. Once you pick the version, only the faults that apply to it stay.

critical3

1.6 and 2.0 TDI: the EGR cooler leaks internally and coolant disappears without a trace

critical

The EGR cooler cools the recirculated exhaust gas before it enters the intake again, and coolant flows through it while it does so.

Applies to the engine CBBB.

Repair: 600–1,500 EUR

2.0 TDI (EA188, EA189): the hex drive of the oil pump rounds off

critical

The balance shaft module drives the oil pump through a hexagonal shaft stub.

Applies to the engine CBBB, CFGB.

2.0 / 1.8 TSI (EA888 gen1 to gen2): the timing chain tensioner lets go

critical

With the 2008 EA888 VW switched from a belt to a chain, and the tensioner of the first two generations turned out weak: as the ratchet mechanism ages it does not hold its position when the engine stops and the oil pressure disappears.

Applies to the engine CCZA, CDAA.

expensive5

2.5 TFSI five-cylinder: oil collects in the air filter housing from the crankcase breather

expensive

The crankcase breather of the five-cylinder 2.5 TFSI leads the oil vapour into the intake, and the stub of the diverter valve sits directly next to it.

Applies to the engine CEPA, CEPB.

Repair: 200–600 EUR

DQ250 (6 speed wet DSG): mechatronics and clutch pack

expensive

The solenoids of the mechatronics unit wear out: slow or harsh shifting, then limp mode.

Applies to the transmission DQ250.

2.0 TFSI (EA113): the high pressure pump cam follower wears through

expensive

The same layout as in the naturally aspirated FSI, only in the turbocharged 2.0: the high pressure fuel pump is driven by the camshaft through a flat cam follower that relies on an oil film.

Applies to the engine BWA.

DQ200 (7 speed dry DSG): mechatronics

expensive

A thin wall of the mechatronics valve body can crack, which causes a loss of pressure.

Applies to the transmission DQ200.

DQ500 (7 speed wet clutch DSG): mechatronics and differential

expensive

The seven speed, wet clutch DQ500 is the DSG of the high torque models (Transporter, Arteon, Tiguan).

Applies to the transmission DQ500.

The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.

A12/00690/20Safety recallFireno date · EU Safety Gate

A bracket mounted on the car body side can damage the fuel tank in the event of a crash. Consequently, fuel may leak close to a source of ignition, increasing the risk of fire.

Engines and transmissions in this generation

Common questions

About this generation

Which years does this page cover?

2006–2014. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.

Does the fault apply to every car like this?

No. It depends on the engine and the transmission too.

Is it free?

The fault list is.

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

A fault on the list does not mean the car you are looking at has it.
A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
