Other Faults on This Variant

EGR Cooler Failure and Soot Ingestion

Severe

2009-201360,000–120,000 miles£400–£800

The 1.6 TDI common-rail engine has a well-documented EGR cooler failure. Coolant can leak into the intake causing rough running or, in severe cases, catastrophic engine failure from hydro-lock.

Piezo Injector Failure (Siemens/Continental)

Critical

2009-201360,000–120,000 miles£300–£1500

The 1.6 TDI uses Siemens/Continental piezo injectors which are incredibly prone to sudden electrical failure, causing immediate engine shutdown.

EGR Valve and Cooler Blockage

Severe

2009-201370,000–130,000 miles£500–£800

The EGR valve and cooler unit is buried at the back of the engine and frequently blocks with carbon or fails electrically. Replacement is labour-intensive.
