Pre-MOT Inspection Checklist for Porsche Cayenne Owners

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

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the lights — “registration plate lamp(s) inoperative in the case of multiple lamps or light sources”

  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 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.

Where the Porsche Cayenne is most common

Across every Cayenne model year on record (2003–2022): 51,490 Porsche Cayenne cars tested in a recordable postcode area, across 97,164 tests. Birmingham (B) has the most, with 1,763 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Porsche Cayenne cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
