About This Data
The 1990 Porsche 944 has an MOT pass rate of 68.3% based on 7,074 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 117,527 miles on the odometer. With a 31.7% failure rate, the 1990 944 is rated as "Good" for MOT reliability.
If you own or are considering buying a 1990 Porsche 944, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm). With an average mileage of 117,527 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Brakes — 1.6% of failures
Brakes issues account for 1.6% of MOT failures on 1990 Porsche 944 models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Suspension — 1.5% of failures
Suspension issues account for 1.5% of MOT failures on 1990 Porsche 944 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Lamps, reflectors and electrical equipment — 1.3% of failures
Lamps, reflectors and electrical equipment issues account for 1.3% of MOT failures on 1990 Porsche 944 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
