2006 Audi A4 2.0L Diesel · ET06 TJU

Recurring issues with braking system components and electrical warning indicators define the mechanical profile of this Audi A4. The most recent test on 18 February 2026 resulted in a pass, but the record shows a pattern of persistent advisories regarding the deterioration of both nearside and offside rear brake hoses, a condition that has been noted in multiple consecutive tests dating back to 2022. Furthermore, the vehicle has experienced recent failures related to major faults, including an electronic stability control warning lamp and a split nearside front inner drive shaft CV boot, alongside repeated advisories concerning an engine malfunction indicator lamp (EML). The vehicle has covered 181,007 miles over its approximately 20-year lifespan, representing an average annual usage of roughly 9,050 miles. This mileage accumulation is consistent with typical age-related wear for a vehicle of this era. While the mileage is not excessively high for its age, the cumulative effect of these miles is evident in the recorded wear on consumables and suspension components, such as the repeated advisories for worn suspension arm bushes and pitted front brake discs. Prospective buyers should pay close attention to the braking system and steering geometry during a test drive. Given the long-standing advisories for deteriorated rear brake hoses, it is essential to inspect these for any signs of bulging or further cracking, as failure can lead to sudden pressure loss. The history of track rod end and drive shaft boot issues suggests that the steering and drivetrain linkages may require close scrutiny; listen for any rhythmic clicking sounds when turning the steering wheel at low speeds or knocks and knocks when driving over uneven surfaces, which could indicate worn ball joints or CV joints. Electrical and engine management systems also require verification. The recurring engine EML advisory and the recent major failure regarding the electronic stability control lamp mean that any dashboard warning lights should be treated with caution. Ensure that all warning lamps, including the supplementary restraint system (SRS) light, function correctly during the initial ignition cycle. Additionally, check for any steering pull or uneven tyre wear, which may stem from the previously recorded issues with suspension arm bushes and track rod ends.
