Pre-MOT Inspection Checklist for Proton Impian Owners

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

  • the steering — “steering rack gaiter missing or no longer prevents the ingress of dirt”

    With the wheels straight, rock the steering wheel gently with the engine off — more than about an inch of free play before the wheels move is worth investigating. Split rack gaiters are cheap to replace and commonly recorded.

  • the suspension joints — “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 wipers and washers — “wipers blade defective”

    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.

Derived from the DVSA failure strings testers recorded for the Proton Impian. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
