2009 Audi TT 2.0L Diesel · OV59 NCE

The most recent MOT test on this 2009 Audi TT, dated 25 August 2026, resulted in a fail with two major defects concerning the rear suspension spring mounting areas, both nearside and offside, which were recorded as excessively corroded and significantly reducing structural strength of the spring arm. Following corrective work, the vehicle was presented again on the same date and achieved a pass, retaining only an advisory note for slight corrosion to the offside rear brake hose ferrule. Looking at the broader test history, the maintenance trend is best described as stable but with a gradually worsening rear suspension condition; the August 2025 test produced dangerous tyre failures alongside an anti-roll bar linkage dust cover defect, and brake issues have been a recurring theme with disc wear advisories in June 2024 and again in August 2025. The pattern suggests a vehicle that has received timely remedial work to clear advisories and major defects, yet underlying wear on suspension, braking, and underbody components is becoming more pronounced with age. With a recorded mileage of 111,015 miles over approximately seventeen years, this TT has averaged around 6,530 miles per year, which is broadly typical for a vehicle of its age and suggests regular use rather than extended periods of standing. There are no significant gaps in the MOT record that would imply long periods of inactivity, although the test intervals are annual rather than indicating rapid mileage accumulation. Consistent usage of this nature is generally favourable for mechanical condition, as it prevents severe corrosion from developing through standing and keeps lubricants and seals working, but it does mean that suspension components, bushes, brake discs, and drivetrain parts have accumulated meaningful wear. The cumulative effect of this mileage on a seventeen year old Audi is now manifesting as structural corrosion in the rear suspension mountings, which is a known concern for vehicles of this era operating in the UK climate. Given the recurring brake and suspension defects, particular attention should be paid to the rear suspension assembly during any pre-purchase inspection. The advisories on brake disc pitting and scoring from 2024 and 2025 indicate progressive wear, and a buyer should now expect that brake discs and pads, particularly at the front, may be approaching the point of replacement. On a test drive, listen for clonks or knocks from the rear suspension over bumps and uneven surfaces, which would suggest worn bushes, corroded spring seats, or weakened mounting areas consistent with the recent major defects. The offside rear brake hose corrosion advisory should also prompt a physical examination of all flexible brake hoses for surface rust and perishing, as age related degradation of these hydraulic components can lead to spongy braking or, in worst cases, hose failure under pressure. Additionally, inspect the front tyres closely for uneven shoulder wear, which would indicate suspension geometry or alignment issues, and check that the anti-roll bar linkage replaced after the August 2025 test is seated correctly with an intact dust cover. Beyond the recorded defects, a seventeen year old Audi TT warrants several age related checks regardless of mileage. Tyre sidewalls should be examined for cracking or perishing from age, even if the tread depth appears adequate, as rubber degrades with calendar exposure. The 12 volt battery should be tested for cranking performance, particularly if the vehicle has seen any periods of infrequent use, and the charging system verified for stable voltage. Brake calipers, especially on a vehicle that may have stood, can suffer from seized slider mechanisms leading to uneven pad wear and pulling under braking, so each caliper should be checked for smooth operation. Fluid condition is critical on a car of this age; coolant, brake fluid, and the Haldex or gearbox oil if applicable should be inspected for age related degradation, with brake fluid in particular requiring replacement every two to three years due to moisture absorption. Finally, verify the service book history for evidence of regular cambelt and water pump replacement on the timing chain or belt equipped engine, as neglected timing components on Audi TFs can lead to catastrophic engine failure, and inspect the underbody, sills, and subframe mountings for any corrosion beyond the documented rear suspension issues, as structural integrity on early TT models is a recognised area of concern.
