What we know

5.2 fails per 100 MOT tests at 12 years, against 3.7 for all class 4 vehicles tested at 12 (all test years). The Renault Grand Scenic fails more 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.
