Pre-MOT Inspection Checklist for Knaus Motorhome Owners

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

  • 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 — “srs malfunction indicator lamp warning lamp indicates a fault”

    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 wipers and washers — “wipers does not clear the windscreen effectively”

    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.

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