1998 Volkswagen Passat — MOT failures & pass rate
2,488 MOT tests on the 1998 Volkswagen Passat are in this dataset, and 71.5% of them passed. Large family cars of a similar age fail 27.4% of the time, so this is 1.1pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (16.2%) and suspension (13.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, ball joint and joints — headlamp aim alone was recorded 259 times.
Condition tracks the odometer closely. Failures run at 20.4% in the 30-60k band and 30.1% in the 150k+ band, a 9.7-point spread.
The diesel cars hold up better: 26.9% fail against 30.3% for petrol, a 3.4-point gap across 2,488 tests.
Brakes is the most common advisory, noted on 34.9% of tests — work that passed today but is likely due soon.

What to check before buying a 1998 Passat
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.
- Suspension (13.7% 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.
- Body, structure & corrosion (9.8% 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+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
