Pre-MOT checklist for NX 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
Feel for a spongy pedal or pulling to one side; check pad wear through the wheel spokes if visible
Replace smeared wiper blades and top up washer fluid — both are test items
Walk round with all lights on: one blown bulb is the most avoidable fail there is

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.
