Pre-MOT Inspection Checklist for Fiat 500L Owners

These checks follow this Fiat 500L's own most-recorded failure strings, starting with what a tester is most likely to flag on a Fiat 500L.

• 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 — “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 — “stop lamp not working”

  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.

Where the Fiat 500L is most common

Across every 500L model year on record (2013–2021): 25,092 Fiat 500L cars tested in a recordable postcode area, across 64,240 tests. Birmingham (B) has the most, with 919 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Fiat 500L cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →
