2017 Peugeot Expert — MOT failures & pass rate
Across 25,461 MOT tests, the 2017 Peugeot Expert recorded an 85.0% pass rate. Vans of a similar age fail 17.7% of the time, so this is 2.7pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
Lighting & signalling dominates the failure mix at 10.8% of all tests — 5.9 points clear of brakes, so it is the first thing to check.
At component level the recurring items are registration plate lamp(s), headlamp aim and wipers — registration plate lamp(s) alone was recorded 962 times.
A 150k+ example is materially riskier than a 0-30k one: 22.1% versus 7.6%.
Advisories point at the next bill rather than this one: brakes was flagged on 18.8% of tests without failing them.
The trend is worsening — 12.9% of tests failed in 2021 against 17.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 Expert
On a 2017 Expert, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.8% of tests. Check these areas before you commit.
- Lighting & signalling (10.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (4.8% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (4.2% 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.
