2001 Audi A6 1.9L Diesel · Y207 CBA

A pattern of recurring minor leaks, corrosion and intermittent lighting faults dominates this 2001 Audi A6’s MOT history, with the most recent test on 7 November 2025 recording a pass but still flagging an oil leak, dim position lights and corroded rear coil springs. Earlier years show repeated advisories for brake‑hose ferrule corrosion, deteriorating CV‑boot seals and, on two occasions, outright failures of stop‑lamp assemblies and headlamp lenses. The record therefore sketches a vehicle that has managed to meet the legal threshold for roadworthiness while consistently presenting low‑level defects that have never escalated into a catastrophic failure but have required repeated attention. At 210,772 mi the car averages roughly 8 400 mi per year, which sits below the UK average of about 12 000 mi annually for a vehicle of this age. The relatively modest annual mileage suggests periods of lighter use or possible extended storage intervals, both of which can accelerate rubber and hose ageing – a factor reflected in the repeated brake‑hose ferrule corrosion and CV‑boot deterioration. Low mileage does not automatically equate to component longevity; rather, it means that wear items such as suspension bushings, brake pads and tyres may have been subjected to fewer load cycles but could still suffer from age‑related hardening or cracking, especially where moisture ingress has been noted. When inspecting the car, give particular focus to the oil‑leak source; look for fresh oil stains around the valve cover, oil pan or front engine seals, and listen for any drips while the engine is idling. The brake hoses on both rear wheels have been flagged for ferrule corrosion – feel the rear pedal for a spongy or inconsistent response and check for any external hose cracking or fluid seepage. The rear coil springs were recorded as corroded on both sides, so examine the rear suspension for rust‑stained springs, uneven ride height or excessive play in the rear shock absorbers, and be alert to any knocking noises over bumps that could indicate compromised spring integrity. Lighting and CV‑boot issues also merit close scrutiny. Verify that all stop lamps illuminate correctly and that the headlamp lenses are free from cracks or severe clouding, as previous failures could have been remedied only temporarily. Inspect the CV boots on both front and off‑side shafts for torn rubber, dried edges or grease leakage, and rotate the wheels to feel for any play that might signal impending joint failure. Finally, although the tyres have not been recorded as worn in the latest tests, the 2022 advisories about edge wear suggest the need for a fresh tread depth check and a visual inspection for sidewall cracks, especially given the vehicle’s age and storage history. Addressing these specific items before purchase will give a clearer picture of the car’s current mechanical condition and the scope of imminent maintenance.
