2006 Audi A6 2.7L Diesel · RO06 XEX

The most recent MOT recorded on 14 December 2021 resulted in a failure, with major defects noted for both front shock absorbers leaking fluid, excessive play in the nearside front wheel bearing, insufficient tread depth on both front tyres and a non‑functioning windscreen washer system. An advisory about the central front undertray not being fully secure was also logged. This contrasts with earlier years where the car passed but accumulated a series of advisories, indicating that the condition of the front suspension and related components has been deteriorating rather than improving. At 190,785 miles for a 2006 model the average annual mileage works out at roughly 9,500 mi, which sits squarely within the normal UK usage envelope. There are no obvious large mileage gaps in the MOT record, suggesting the vehicle has been driven fairly consistently over its life rather than sitting idle for extended periods. The cumulative distance does place the car well into the wear‑life of many consumables – particularly the suspension bushings, shock absorbers, wheel bearings and tyre tread – and it is reasonable to expect these items to be approaching the end of their serviceable life. A prospective buyer should give the front suspension a thorough examination. Inspect the shock absorbers for any oil seepage around the seals and check for reduced damping by pressing the front corners and feeling for a smooth rebound. Examine the anti‑roll bar linkage pins and the upper and lower suspension arm bushes for looseness, cracks or excessive play; worn bushings often manifest as clunking noises over bumps or a vague wandering sensation in the steering. The nearside front wheel bearing should be spun by hand to detect any roughness or grinding, and a test‑drive should be used to listen for a humming or growling noise that varies with wheel speed, which would confirm bearing wear. Both front tyres are already flagged as marginal on tread depth, so verify the remaining tread, look for uneven wear patterns that could indicate alignment or suspension issues, and be prepared to replace them promptly. The windscreen washer pump and associated hoses should be tested for operation, as a failed system can impair visibility in adverse weather. Finally, ensure the central front undertray is securely fastened to prevent debris ingress that could damage the chassis or under‑body components. Given the vehicle’s age, independent of the recorded defects, a comprehensive age‑related inspection is advisable. Check the tyre sidewalls for cracking, dry rot or bulging, which can develop even on low‑mileage cars that have been stored for long periods. Examine the 12 V battery for terminal corrosion and assess its charge hold, as batteries over twenty years old often require replacement. Look for corrosion on the chassis, especially around the wheel arches and suspension mounting points, and verify that any rust is surface‑level rather than structural. Inspect all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – and consider a full service if the last change is not documented, since fluids degrade with time even without mileage. Finally, review the service book for evidence of regular oil changes, timing belt or chain replacement (if applicable), and any recorded major services, as a well‑documented maintenance history will mitigate many of the age‑related risks inherent in a twenty‑year‑old Audi A6.
