Mercedes-Benz Eqa 250+ MOT pass rate & common failures
Across 4 model years and 13,505 tests, the Mercedes-Benz Eqa 250+ passes its MOT 91.5% of the time. That is effectively the same as all cars of a similar age (8.5% fail rate), so the MOT record here is unremarkable in either direction. Its most common failure areas are tyres, visibility and lighting & signalling.
What the MOT record shows
Tyres dominates the failure mix at 6.8% of all tests — 5.4 points clear of visibility, so it is the first thing to check.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 326 times.
A 90-120k example is materially riskier than a 0-30k one: 2.5% versus 6.7%.
Advisories point at the next bill rather than this one: tyres was flagged on 27.6% of tests without failing them.
The trend is worsening — 1.0% of tests failed in 2023 against 8.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a Mercedes-Benz Eqa 250+
- Tyres (6.8% 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.
- Visibility (1.5% 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.
- Lighting & signalling (0.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
