2001 SEAT Arosa — MOT failures & pass rate
Across 1,844 MOT tests, the 2001 SEAT Arosa recorded a 74.1% pass rate. All cars of a similar age fail 27.1% of the time, so this is 1.3pp better than the group it competes with. Failures cluster in lighting & signalling, body, structure & corrosion and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 16.2% of tests against 9.9% for the next-worst category.
At component level the recurring items are headlamp aim, service brake performance and position lamp — headlamp aim alone was recorded 128 times.
Mileage is the strongest signal on the record: 21.4% of 0-30k cars fail, rising to 28.9% once past 150k.
The petrol cars hold up better: 25.1% fail against 27.5% for diesel, a 2.4-point gap across 1,844 tests.
Suspension is the most common advisory, noted on 38.7% of tests — work that passed today but is likely due soon.

What to check before buying a 2001 Arosa
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 16.2% of tests. Start there.
- Lighting & signalling (16.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (9.9% 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+.
- Suspension (9.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
