1998 Volkswagen Transporter — MOT failures & pass rate
25,596 MOT tests on the 1998 Volkswagen Transporter are in this dataset, and 69.3% of them passed. Against vans of a similar age (29.6% fail rate), the 1998 Transporter comes out 1.1pp worse. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 18.8% of tests against 13.6% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, headlamp aim and service brake performance — component mounting prescribed areas alone was recorded 3,230 times.
Mileage matters less than usual here: the 1998 Transporter fails 32.1% of the time in the 0-30k band and 33.1% at 150k+, a spread of only 0.9 points.
The petrol cars hold up better: 26.4% fail against 30.9% for diesel, a 4.5-point gap across 25,595 tests.
Brakes is the most common advisory, noted on 43.4% of tests — work that passed today but is likely due soon.

What to check before buying a 1998 Transporter
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 18.8% of tests. Start there.
- Lighting & signalling (18.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.6% 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.
- Suspension (13.1% 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.
