Pre-MOT checklist for 4 Trophy 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
An illuminated engine management light is a Major MOT defect. Read the code, repair the cause, then confirm the light stays off — clearing a code alone is not a repair.
