Est. Repair Cost: £250–£500
Warning Signs:

Front wheel spin under hard acceleration, No power to rear wheels

What to Inspect:
  • Check for Haldex fluid service history (every 3 years/30k miles)

DSG Gearbox Low-Speed Jerkiness

ModerateGearbox & Transmission

The 7-speed DSG can feel jerky or hesitant at low speeds, particularly in stop-start traffic and when manoeuvring. A software update often improves but doesn't always cure it.

Warning Signs:

Jerky low-speed manoeuvring, Delayed pull-away, Gear shunt in traffic

What to Inspect:
  • Drive extensively in town traffic
  • Check for DSG software updates
  • Ask about DSG fluid service history

Front Assist Sensor Failure in Rain

ModerateElectrics & Electronics

The front radar sensor for adaptive cruise and emergency braking can trigger false warnings or fail in heavy rain, causing repeated "Front Assist Unavailable" alerts.

Est. Repair Cost: £0–£400 (Sensor/Software)
Warning Signs:

Front Assist warning in rain, False emergency braking warnings, Adaptive cruise cutting out

What to Inspect:
  • Test the car in wet conditions if possible
  • Check for persistent warning lights on the dashboard
  • Ask if the sensor has been replaced or recalibrated

Front Suspension Knocking

MinorSuspension & Chassis

The front suspension can develop knocking sounds over bumps due to worn top mounts or anti-roll bar drop links. More pronounced on cars with larger alloy wheels.

Est. Repair Cost: £100–£350
Warning Signs:

Knocking or clunking over bumps, Noise when turning at low speed

What to Inspect:
