Top failures
Engine warning light inoperative or lit 3.65%
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
Ball joint dust cover no longer sealed 2.84%
A damaged dust cover lets dirt into the joint, speeding wear, so the joint may need replacing later.
Track rod end dust cover damaged 2.66%
A damaged dust cover lets dirt into the ball joint, which speeds up wear and may lead to a costly replacement.
Rigid brake pipe excessively corroded 2.13%
Badly corroded brake pipes can leak or fail, which can cause a loss of braking, so repair is urgent.
Suspension arm pin/bush excessively worn 2.06%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Anti-roll bar linkage dust cover unsealed 1.73%
A damaged dust cover lets dirt into the linkage joint, speeding wear and possibly needing a future repair.
Common advisories
Brake pipes corroded and greasy (14.8%) · Engine oil leak, not excessive (9.58%) · Tyre worn close to legal limit (9.5%) · Sub-frame showing corrosion (8.78%) · Suspension arm pin/bush showing wear (8.39%) · Tyre slightly damaged or cracking (7.39%)
