What the MOT tests show
What we know
2.5 fails per 100 MOT tests at 9 years, against 2.4 for all class 4 vehicles tested at 9 (all test years). That is about average.
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.
The Mercedes-Benz Sprinter is a commercial or van-based vehicle: it is compared with all class 4 vehicles, cars and vans together, so part of any difference can come from how vans are used.
