Other Faults on This Variant

DSG 7-Speed DQ200 Dry Clutch Shudder

Moderate

2010-201430,000–100,000 miles£100–£2500

The DSG 7-speed DQ200 dry clutch gearbox in the Passat B7 has a well-documented shudder issue from a standing start. VW issued multiple software and mechatronic updates.

EGR Cooler Failure

Severe

2010-201470,000–140,000 miles£500–£900

EGR cooler failure on the Passat B7 2.0 TDI causes coolant loss and white smoke. The internal corrosion of the cooler allows coolant into the intake manifold.

Timing Belt Failure (CFFB/CEGA Engines)

Critical

2010-2014100,000–140,000 miles£400–£700

Unlike the older PD-engine Passats, the B7 common rail 2.0 TDI uses a timing belt. The belt interval is 140,000 miles but many specialists recommend 100,000 miles given the cost of engine damage.
