Audi TT — reported problems
CarFaultIQ holds 10,910 evidence records for the Audi TT (1999–2023), drawn from official sources and owner complaints.
What owners report: issue areas
Owner complaints are classified by the system they concern: 826 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.
- Electrical system288 (34.9%)
- Powertrain (transmission & drivetrain)106 (12.8%)Official recall records for this system: 4, covering model years 2004–2010.
- Engine84 (10.2%)Official recall records for this system: 1, covering model years 2000–2006.
- Air bags (restraint system)52 (6.3%)Official recall records for this system: 9, covering model years 2000–2023.
- Fuel system46 (5.6%)Official recall records for this system: 6, covering model years 2000–2019.
- Tires & wheels42 (5.1%)
Other / uncategorized: 18 classifications (2.2%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.
These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.
What the records are about, by source
Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.
- Owner complaints (636 records, model years 2000–2016) are most frequently classified under: electrical system, powertrain (transmission & drivetrain) and engine.
- Manufacturer communications (10,188 records, model years 1999–2023) are most frequently classified under: equipment & accessories, electrical system and engine.
"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
Mileage reported when the issue occurred
- 418reports included a mileage
- 59,157average of those mileages
This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Diagnostic codes found in evidence for this vehicle
These codes appear by explicit identifier in official records matched to this exact model and year.
A code appearing in a record means the code was named in that document. It is not a diagnosis of this vehicle, not a fault this vehicle has, and not an indication of urgency. Diagnosis requires reading live data from the vehicle.
