What we know

1.8 fails per 100 MOT tests at 10 years, against 2.8 for all class 4 vehicles tested at 10 (all test years). The Volkswagen CC fails less often here.

Why it matters

An exhaust, emissions and leaks fail stops the car passing until it is fixed; the most common one is rated major by DVSA.

What to check

Start the car from cold and look for smoke at the exhaust, listen for blowing joints, and look under the engine and gearbox for fresh oil or fluid drips.
