Volkswagen Golf Mk7 1.4 TSI 125bhp — Front Anti-Roll Bar Drop Link Wear

The front anti-roll bar drop links wear out on heavily potholed UK roads, causing an annoying knocking sound at low speeds.

Severity

Minor

DIY Difficulty

Easy

Est. Cost

£60–£120

OBD Codes

None

Symptoms

Light knocking or rattling noise from the front suspension over rough roads
Noise is most pronounced at 10-20mph over speed bumps

Root Cause

The ball joints at either end of the drop link lose their grease and the nylon cups wear out, creating play in the joint.

How To Fix

Jack the car and check for vertical play in the drop link.
Replace in pairs (left and right) for best results.
A very simple DIY job, but the nuts are often seized and need to be cut off.
Cost: £60-120 at a garage.

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.
