Polo: middle-of-the-pack on first-time pass
Across 766,784 MOT tests, the Polo returns 72.7% first-time pass — below the UK fleet average. The single most-logged Major fail is a number-plate lamp out. A torn steering gaiter and a split CV-joint boot round out the top three. Average tested mileage sits at 67,389, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Report of EPC light coming on in 2010 Polo 1.2 TSI and engine becoming sluggish. EPC = Electronic Power Control, which is the drive by wire system between the accelerator pedal and the engine.

Buying or keeping a Polo?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Polo and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
