Pre-MOT Inspection Checklist for Infiniti QX30 Owners

These checks follow this Infiniti QX30's own most-recorded failure strings, starting with what a tester is most likely to flag on a Infiniti QX30.

• the coil springs — “coil spring fractured or broken”

  Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.

• the suspension joints — “linkage ball joint dust cover 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 lights — “headlamp aim too low”

  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.
