About Audi 100 Avant MOT Data

The Audi 100 Avant is a niche vehicle in the UK, with 2,014 MOT test results recorded in our database spanning 10 manufacture years. It has an overall MOT pass rate of 53.7% and a failure rate of 46.3%, which is below the UK average of approximately 37%.

For Audi 100 Avant owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on brakes and suspension for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific 100 Avant is likely to perform.

Brakes — 44.8% of failures

Brakes issues account for 44.8% of MOT failures on the Audi 100 Avant. 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 — 37.5% of failures

Suspension issues account for 37.5% of MOT failures on the Audi 100 Avant. 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 — 28.7% of failures

Lamps, Reflectors and Electrical Equipment issues account for 28.7% of MOT failures on the Audi 100 Avant. 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.
