Mercedes-Benz Eqv 300 + MOT pass rate & common failures
The Mercedes-Benz Eqv 300 + appears in 2,864 MOT tests spanning model years 2020–2025, and 90.4% of them passed. Against all cars of a similar age (8.0% fail rate), the Eqv 300 + comes out 1.7pp worse. Its most common failure areas are tyres, body, structure & corrosion and visibility.
What the MOT record shows
One area stands out: tyres, recorded in 5.5% of tests against 2.5% for the next-worst category.
At component level the recurring items are joints, wipers and tread depth — joints alone was recorded 91 times.
Mileage matters less than usual here: the Eqv 300 + fails 8.3% of the time in the 0-30k band and 6.7% at 120-150k, a spread of only 1.6 points.
Tyres is the most common advisory, noted on 14.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 3.2% of tests failed in 2022 against 10.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a Mercedes-Benz Eqv 300 +
- Tyres (5.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Body, structure & corrosion (2.5% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Visibility (1.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
