Pre-MOT Inspection Checklist for Chevrolet Volt Owners

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

• the lights — “malfunction indicator lamp inoperative or indicates a malfunction”

  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.

• 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.

Derived from the DVSA failure strings testers recorded for the Chevrolet Volt. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
