Pre-MOT checklist for 520D M Sport Mhev Auto owners

Based on the failure profile above, ten minutes with a torch before your test removes the most likely fail items:

Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory
A blowing exhaust or visible smoke will fail; warm the engine fully before the test
Replace smeared wiper blades and top up washer fluid — both are test items

Check the engine before the tester does

A stored fault code with the engine light on is an automatic Major defect. Scan and clear resolved faults before booking.
