Pre-MOT checklist for D-Max owners

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

Bounce each corner and listen for clonks over speed bumps — suspension is this model’s (and the UK’s) top failure system
Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
Walk round with all lights on: one blown bulb is the most avoidable fail there is
Look underneath for corrosion around sills and subframes, especially on older cars
Check tread with the 20p test and inspect sidewalls for cracking — tyres close to the limit are the country’s most common advisory

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.
