Pre-MOT checklist for EQC 400 AMG Line 4MATIC 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
Bounce each corner and listen for clonks over speed bumps — suspension is this model’s (and the UK’s) top failure system

Check the engine before the tester does
