2009 Audi TT 2.0L Petrol · AJ09 BFV

A dominant feature of this 2009 Audi TT’s MOT record is the persistent rear‑end corrosion and associated brake wear, with the June 2026 test recording a pass yet still flagging slight play in the off‑side rear anti‑roll bar linkage and corrosion of the rear suspension. Earlier years show a pattern of rear sub‑frame and suspension arm corrosion, a failed rear shock absorber in 2025, and recurring advisories on thin rear brake pads and pitted discs, while occasional major failures have arisen from a non‑functional engine MIL indicator and a faulty windscreen washer. The overall trend is one of repeated corrosion‑related advisories interspersed with isolated electronic and brake issues, rather than a clean, uneventful history. At 147,995 mi the car averages roughly 8,700 mi per annum, a mileage rate that sits comfortably within the normal range for a seventeen‑year‑old vehicle. The MOT entries are spaced roughly yearly, indicating no prolonged periods of inactivity that would mask hidden deterioration. This moderate annual accumulation suggests that wear items such as suspension bushings, shock absorbers, brake discs and pads are likely approaching the latter stages of their service life, while the cumulative mileage also raises the probability of oil‑seal wear and potential exhaust‑system fatigue. When inspecting the rear structure, focus on any audible creaks or clunks over bumps, uneven ride height, and visible rust around the sub‑frame, rear suspension arms and anti‑roll bar linkage. Feel for excessive play when the rear wheels are rocked and watch for any fluid seepage from the rear shock absorbers, which were recorded as having negligible damping effect in 2025. The battery mounting should be checked for secure attachment, as multiple advisories have noted an insecure carrier that could lead to vibration‑induced damage. A thorough visual examination of the rear wheel arches and under‑body for flaking or deep corrosion will help gauge whether the structural integrity remains within safe limits. The engine management light failures recorded in 2022 and 2024 warrant a diagnostic scan to confirm that the MIL is now extinguished and that no stored fault codes persist, as lingering issues could affect emissions compliance and drivability. Verify that the engine runs smoothly at idle and under load, with no hesitation or roughness. Given the long‑standing brake disc and pad wear advisories, inspect disc thickness and surface condition for deep scoring, and assess pad material for uneven wear; a pulsating pedal or excessive pedal travel would indicate compromised braking performance. Finally, confirm that the oil leak noted in 2021 is no longer active and that the minor exhaust leak does not produce audible hissing or excessive smoke, both of which could signal deteriorating gaskets or cracked pipework.
