VW Golf

The timing chain on the 1.2 TSI EA111 (CBZA) stretches prematurely from manufacturing defects. Possible from as little as 30,000–40,000 km. Defective tensioners and guide rails worsen the problem.

Symptoms: Rattling on cold start, MIL, rough idle in cold weather

The 1.2 TSI EA111 is known for above-average oil consumption. Causes are piston rings and the turbocharger. Check oil level regularly between service intervals.

Symptoms: Oil consumption above 0.5 L/1,000 km, bluish smoke, oil warning light

Like other TSI engines of this generation the 1.2 TSI tends toward increased oil consumption from piston ring leakage. Oil level check at every fill-up recommended.

Symptoms: Low oil level warning, bluish exhaust smoke, oil consumption above 0.5 L/1,000 km

Short-trip use and oil starvation from chain problems can damage the 1.2 TSI turbocharger. Carbon deposits in the turbo cause boost pressure loss and power reduction.

Symptoms: Whistling noise from turbo area, power loss, blue smoke, increased oil consumption

Turbocharger shaft seals on the small EA111 turbo wear with high oil consumption or poor maintenance. The turbo is physically small and sensitive to poor-quality oil.

Symptoms: Blue smoke on acceleration, power loss, oil in intake tract or charge air hose

In the Golf VI rust forms preferentially at the wheel arch edges and on the tailgate — especially if body damage has been repaired unprofessionally. VW economised on the factory corrosion protection for engine, chassis and gearbox.

In the Golf VI water enters the boot through a blocked drain channel in the tailgate or through a cracked washer jet supply line to the rear wiper. Wet tail light connectors lead to corrosion and electrical problems.

The Golf VI uses a continuously running compressor without a magnetic clutch (externally regulated). If it fails, metal particles spread throughout the refrigerant circuit. Without a complete system flush the replacement compressor will quickly be destroyed.

The rear brake calipers of the Golf VI seize through corrosion — especially on cars that rarely brake hard. The integrated handbrake mechanisms jam after standing still. GTI models with larger calipers are particularly affected.

In the Golf VI the ignition lock can jam or the electronic steering lock can activate unintentionally, preventing the car from starting. The problem occurs mainly on early production cars.

The electric power steering of the Golf VI can fail due to ECU failures or motor faults. The steering suddenly becomes heavy, which can be dangerous at motorway speeds. A warning light appears on the dashboard.
