Pre-MOT Inspection Checklist for Smart Mcc Forfour Owners

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

• the suspension joints — “ball joint excessively worn”

  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 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.

• 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.
