For this generation we cover 3 engines and 11 known faults, each with the mileage range where it usually appears.
The most expensive known risk is TCT / DCT actuator & clutch: it usually appears at 60,000–160,000 km and costs €800–2,200 to fix.
In UK roadworthiness tests in 2024, at 50–100 thousand km this model most often failed on: lights, wipers and visibility (8.2 %), tyres and wheels (7.0 %), steering (4.8 %). It fails more often than an average car of the same age and mileage on: steering, exhaust, emissions and leaks. It fails less often than average on: brakes, body and corrosion.
