Tiguan R-Line Tech Tdi 4m Sa: a strong MOT record by UK norms

Across 2,518 MOT tests, the Tiguan R-Line Tech Tdi 4m Sa returns 89.1% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. Windscreen damage and a seriously damaged tyre round out the top three. Average tested mileage sits at 34,928, 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.

Owner reports · Honest John

What owners actually report.

Verbatim faults logged by owners on honestjohn.co.uk over recent years. We didn't summarise — these are the words people typed in.

What's good

The 2023 Volkswagen Tiguan is an upmarket alternative to SUVs like the Nissan Qashqai and Ford Kuga. It boasts a classy and spacious interior, and is comfortable and easy to drive.

Where it falls short

Looks expensive alongside the very similar SEAT Ateca or Skoda Karoq. Not the most exciting SUV to look at. Other than the R version, not particularly thrilling to drive.

Buying or keeping a Tiguan R Line Tech Tdi 4M SA?

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 Tiguan R Line Tech Tdi 4M SA 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.
