Pre-MOT Inspection Checklist for Audi S6 Owners

These checks follow this Audi S6's own most-recorded failure strings, starting with what a tester is most likely to flag on a Audi S6.

• 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 exhaust and emissions — “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

  Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
