Pre-MOT Inspection Checklist for Smart Roadster Light Owners

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

  • the suspension joints — “track rod end ball joint dust cover damaged or deteriorated,”

    With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.

  • 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 brake pipes — “flexible brake hoses slightly damaged”

    Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
