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

Severe

2015-202140,000–80,000 miles£1200–£1800

Models fitted with the 7-speed dry Dual Clutch Transmission (DCT) suffer from extreme juddering when pulling away, caused by actuator failure.

Air Conditioning Condenser Leak (Stone Damage)

Minor

2015-202140,000–120,000 miles£250–£450
