2021 Mitsubishi L200 Trojan Di-D — MOT failures & pass rate
349 MOT tests on the 2021 Mitsubishi L200 Trojan Di-D are in this dataset, and 89.7% of them passed. All cars of a similar age fail 8.6% of the time, so this is 1.7pp worse than the group it competes with. Failures cluster in lighting & signalling, emissions & environmental and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 6.6% of tests against 3.1% for the next-worst category.
At component level the recurring items are headlamp aim, malfunction indicator lamp and wipers — headlamp aim alone was recorded 16 times.
Mileage matters less than usual here: the 2021 L200 Trojan Di-D fails 7.8% of the time in the 0-30k band and 7.7% at 60-90k, a spread of only 0.1 points.
Tyres is the most common advisory, noted on 16.9% of tests — work that passed today but is likely due soon.

What to check before buying a 2021 L200 Trojan Di-D
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.6% of tests. Start there.
- Lighting & signalling (6.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (3.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (2.9% 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.
