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

EGR Cooler Failure and Soot Ingestion

Severe

2009-201360,000–120,000 miles£400–£800

The 1.6 TDI common-rail engine has a well-documented EGR cooler failure. Coolant can leak into the intake causing rough running or, in severe cases, catastrophic engine failure from hydro-lock.

Piezo Injector Failure (Siemens/Continental)

Critical

2009-201360,000–120,000 miles£300–£1500

The 1.6 TDI uses Siemens/Continental piezo injectors which are incredibly prone to sudden electrical failure, causing immediate engine shutdown.

EGR Valve and Cooler Blockage

Severe

2009-201370,000–130,000 miles£500–£800

The EGR valve and cooler unit is buried at the back of the engine and frequently blocks with carbon or fails electrically. Replacement is labour-intensive.
