Pre-MOT Inspection Checklist for BMW M4 Heritage Owners

These checks follow this BMW M4 Heritage's own most-recorded failure strings, starting with what a tester is most likely to flag on a BMW M4 Heritage.

• the wipers and washers — “wipers blade defective”

  Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.

• the coil springs — “coil spring fractured or broken”

  Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.

• the number plates — “registration plates does not conform to the specified requirements”

  Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.
