Pre-MOT checklist for A3 S Line 35 Tfsi 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
  • Replace smeared wiper blades and top up washer fluid — both are test items
  • Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
Engine management light on?

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.
