1998 Volkswagen Polo — MOT failures & pass rate
4,237 MOT tests on the 1998 Volkswagen Polo are in this dataset, and 71.9% of them passed. That is 1.2 percentage points better than superminis of a similar age, which fail at 29.3%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (11.3%) and suspension (11.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, component mounting prescribed areas and prescribed areas — catalyst emissions alone was recorded 418 times.
Condition tracks the odometer closely. Failures run at 19.9% in the 0-30k band and 39.7% in the 150k+ band, a 19.8-point spread.
Suspension is the most common advisory, noted on 37.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 27.8% of tests failed in 2021 against 29.6% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 1998 Polo
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.3% of tests. Start there.
- Lighting & signalling (11.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.3% 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.
- Brakes (9.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
