These checks follow this Vauxhall Insig Excnav Cdti's own most-recorded failure strings, starting with what a tester is most likely to flag on a Vauxhall Insig Excnav Cdti.
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 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 tyre tread — “tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
