Pre-MOT Inspection Checklist for Porsche Cayenne V6 Diesel Owners

These checks follow this Porsche Cayenne V6 Diesel's own most-recorded failure strings, starting with what a tester is most likely to flag on a Porsche Cayenne V6 Diesel.

• the tyre tread — “tread depth below requirements of 1.6mm”

  Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

• the lights — “registration plate lamp(s) inoperative in the case of a single lamp or all lamps”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

• the brakes — “brake discs significantly and obviously worn”

  Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
