1999 Volkswagen Polo — MOT failures & pass rate
The 1999 Volkswagen Polo passed 74.3% of its 7,895 recorded MOT tests. Superminis of a similar age fail 29.4% of the time, so this is 3.7pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (10.4%) and suspension (9.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, wipers and component mounting prescribed areas — catalyst emissions alone was recorded 801 times.
Condition tracks the odometer closely. Failures run at 16.4% in the 0-30k band and 35.5% in the 150k+ band, a 19.1-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 33.6% of tests without failing them.
The trend is worsening — 25.2% of tests failed in 2021 against 28.1% 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 1999 Polo
On a 1999 Polo, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.4% of tests. Check these areas before you commit.
- Lighting & signalling (10.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.5% 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.
- Emissions & environmental (8.5% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
