Audi Tt (2003)
2003 Audi Tt
CarHunch analysed 9,708 real MOT records for the 2003 Audi Tt. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2003 Audi TT passes its MOT first time only 72.8% of the time, notably below the UK average of 80%, and over half of these cars (51%) have experienced a dangerous defect at some point—a serious concern for buyers considering this model. The high failure rate suggests this is a car that demands careful pre-purchase inspection and thorough maintenance history review.
At nearly 78,000 miles on the median, these TTs are showing their age with an average of 6.24 failures and 31.2 advisories per test, indicating widespread wear across multiple systems rather than isolated problems. Before committing to one of these cars, get a pre-purchase inspection from a specialist Audi mechanic and factor in regular, preventative maintenance costs—this is not a low-upkeep purchase.
What to check before buying a 2003 Audi Tt
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 51% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
