1993 Audi Coupe — MOT failures & pass rate
The 1993 Audi Coupe passed 81.6% of its 348 recorded MOT tests. Against all cars of a similar age (23.4% fail rate), the 1993 Coupe comes out 5.0pp better. Failures cluster in lighting & signalling, emissions & environmental and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 12.6% of all tests — 4.0 points clear of emissions & environmental, so it is the first thing to check.
At component level the recurring items are catalyst emissions, headlamp aim and position lamp — catalyst emissions alone was recorded 35 times.
Mileage matters less than usual here: the 1993 Coupe fails 18.2% of the time in the 60-90k band and 17.9% at 150k+, a spread of only 0.3 points.
Advisories point at the next bill rather than this one: suspension was flagged on 22.7% of tests without failing them.
The trend is worsening — 16.2% of tests failed in 2021 against 18.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 1993 Coupe
On a 1993 Coupe, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.6% of tests. Check these areas before you commit.
- Lighting & signalling (12.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (8.6% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (6.9% 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.
