About the 1999 Audi TT

The 1999 Audi TT is a premium car. Our records list a 1800cc petrol engine, though engines vary between versions. 987 MOT tests were recorded on this model in 2024, making it a less common model in the UK market. Among all models from 1999, the average MOT pass rate is 75%, and this model falls short of that benchmark.

With an average of 122,142 miles recorded at its 2024 MOT tests, Audi TT owners tend to use this car less than the typical driver.

1999 Audi TT Fuel Costs

The 1800cc petrol engine offers a reasonable balance between performance and economy. Expect around 36 mpg in mixed driving, which works out to roughly £1,631 per year with petrol at 174.57p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year).

What does it cost to own a 1999 Audi TT?

Total estimated annual running cost is £2,561 (£213/month), broken down as £1,631 fuel, £375 road tax, £55 MOT, and £500 predicted repairs. Repair costs are moderate, reflecting the 71% pass rate. Keeping on top of servicing will help avoid surprises.

Audi TT Reliability Trend

Newer Audi TTs pass their MOT more often than older ones, by 15 percentage points on average, which is mostly down to age and wear.

Buying a Used 1999 Audi TT

At 27 years old, the Audi TT is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

Timing Chain / Belt

Watch out

At 27 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.

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 122k 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.
