Pre-MOT checklist for Tf owners
Based on the failure profile above, ten minutes with a torch before your test removes the most likely fail items:
- Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
- Bounce each corner and listen for clonks over speed bumps — suspension is this model’s (and the UK’s) top failure system
- Walk round with all lights on: one blown bulb is the most avoidable fail there is
- 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
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.

- Suspension: advisory follow-up · did the same fail item hold
- Noise, emissions and leaks: advisory follow-up · did the same fail item hold
