Symptoms

Humming, droning, or roaring noise from the wheels that increases with road speed
Noise changes pitch or disappears when turning slightly left or right
Slight vibration felt through the steering wheel at motorway speeds

Root Cause

The sealed bearing unit loses its grease over time, or water ingress causes the steel balls/rollers to pit and rust. Impact damage from potholes can also cause a flat spot on the bearing race.

How To Fix

Jack the car up and check for play by rocking the wheel at the 12 and 6 o'clock positions.
Spin the wheel and listen for a rough rumbling sound.
Press out the old bearing and press in a new OEM-quality bearing (e.g. SKF, FAG, SNR).
Cost: £120-250 per corner

Other Faults on This Variant

DSG Mechatronic Unit Failure (DQ200 7-Speed)

Critical

2012-201950,000–100,000 miles£500–£1500

If fitted with the 7-speed dry clutch DSG (DQ200), the mechatronic control unit is highly prone to internal pressure leaks and electrical failure.

Turbo Actuator Wastegate Rattle

Minor

2012-201930,000–90,000 miles£20–£100

A metallic rattling noise from the turbocharger on a cold start or when decelerating is a common annoyance caused by a loose wastegate actuator rod.

Air Conditioning Condenser Leak (Stone Damage)

Minor

2012-201940,000–120,000 miles£250–£450

The air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
