Average for cars of the same age and mileage
Top MOT failures
- 1
Exhaust has major gas leak 4.23% of tests
A major exhaust leak can let poisonous gas into the car and is illegal, so it must be repaired before driving.
- 2
Position lamp not working 4% of tests
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
- 3
Wiper blade not clearing windscreen 3.6% of tests
Wipers that do not clear the windscreen reduce visibility in rain, which is a safety risk, so replace them.
- 4
Headlamp beam pattern obviously incorrect 3.38% of tests
A wrongly shaped beam can dazzle other drivers and reduce your own view of the road, so the lamps need correcting.
- 5
CV joint boot split or insecure 3.33% of tests
A split CV boot lets dirt in and grease out, so the joint wears and may need full replacement.
- 6
Stop lamp not working 3.22% of tests
A failed stop lamp means drivers behind cannot see when you brake, a safety risk that must be fixed.
- 7
Engine warning light inoperative or lit 3.04% of tests
An engine warning light that is lit or not working can hide faults, so diagnosis is needed before buying.
- 8
Lambda reading outside specified limits 2.75% of tests
An out-of-range lambda reading suggests poor fuel mixture or a failing catalytic converter, so diagnosis is needed.
