Pre-MOT Inspection Checklist for Smart Forfour Coolstyle Owners

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

• 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 suspension joints — “ball joint dust cover severely 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 battery — “battery(ies) insecure”

  Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
