About the 1990 AUDI 100

The 1990 AUDI 100 is a premium with a 2226cc petrol engine. 58 of these vehicles were MOT tested in 2026, making it a rare model on UK roads. Among all cars from 1990, the average MOT pass rate is 79%, and this model beats that benchmark.

With an average of 129,885 miles at 36 years old, AUDI 100 owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

1990 AUDI 100 Fuel Costs

The 2226cc petrol engine offers a reasonable balance between performance and economy. Expect around 30 mpg in mixed driving, which works out to roughly £1,592 per year at current petrol prices of 142p per litre (based on 7,400 miles per year).

Buying a Used 1990 AUDI 100

At 36 years old, the AUDI 100 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins.

Note: with only 58 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

Based on the 1990 AUDI 100's fuel type, age, and engine size, these are the most likely problem areas to check.

Timing Chain / Belt

Watch out

At 36 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.

Oil Consumption

Medium risk

Larger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Clutch Wear

Watch out

With an average of 130k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.

Brake Discs and Pads

Medium risk

High-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.

Engine Mounts

Medium risk

Worn engine mounts cause excessive vibration and movement. Replacement costs £150-£400 per mount. Check for vibration at idle with the bonnet open.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
