Pre-MOT Inspection Checklist for London Taxis Int TX4 Owners

These checks follow this London Taxis Int TX4's own most-recorded failure strings, starting with what a tester is most likely to flag on a London Taxis Int TX4.

• the suspension joints — “pins and bushes pin or bush 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 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 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.
