Known Issues
Clutch Wear:
Can be susceptible to premature wear, especially in urban driving with the 2-Tronic gearbox. Manual clutch wear is generally reasonable.
Engine Mounts:
Can deteriorate over time, leading to increased vibration.
Exhaust System:
Corrosion can affect exhaust components, particularly in areas with road salt.
2 Tronic Gearbox Actuator:
The clutch actuator for the 2-Tronic gearbox can be a failure point, leading to shifting issues or complete failure to engage gear.
Brake Wear:
Front brake pads and discs may wear relatively quickly due to the car's light weight and city use.
Air Conditioning Performance:
Can sometimes be less potent than larger vehicles, particularly in very hot climates.
Rear Wheel Bearing:
Rear wheel bearings can sometimes develop noise or wear prematurely.
