2008 Audi A4 2.0L Diesel · HG08 EVY

The 2008 Audi A4 presents a mixed but broadly stable mechanical picture following its most recent MOT pass on 24 April 2026 at 162,874 miles. That pass came just hours after a failure on the same day at 162,872 miles, where the tester flagged an excessively cut offside rear brake hose, headlamp aim faults, and an insecure battery. The rapid retest suggests those specific items were addressed promptly, yet the pass still carried a heavy advisory load. Front brake pads and all four brake discs were wearing thin or pitted, both front shock absorbers were corroded, the rear sub-frame and its mounting areas showed corrosion, and the nearside rear tyre had a cut. The offside rear wheel was slightly distorted and the battery remained insecure. These are not fresh defects. They represent a pattern of superficial corrosion and deferred minor repairs that has persisted across multiple tests without escalating into serious structural failure. Mileage accumulation sits at roughly 9,000 miles per year, which is typical for an eighteen-year-old executive saloon. The record shows a jump of 9,683 miles between the March 2025 test at 153,191 miles and the March 2026 test at 162,505 miles, indicating consistent annual use rather than long periods of inactivity. No glaring gaps appear in the MOT chronology, and the steady odometer progression supports the view that the car has been driven regularly. That regular use has kept consumable wear predictable, but it has also allowed corrosion-related faults to accumulate gradually rather than being caught early. A buyer should focus the physical inspection on the areas the MOT record repeatedly highlights. The rear sub-frame and its mounting points have been noted as corroded but not seriously weakened in both March 2026 and March 2025, meaning the corrosion is being monitored rather than repaired. That needs a close visual check underneath to confirm there is no perforation or scaling that could compromise structural integrity. The front shock absorbers were flagged as corroded in both 2025 and 2026, and the nearside front unit had a light oil misting in March 2025, so damping performance and seal condition should be tested on a road run. Brake components are a recurring theme. The April 2026 failure identified a cut offside rear brake hose, and both rear hoses have shown corrosion to their ferrules across multiple tests. All four discs and pads were wearing thin or pitted in the latest test, meaning a full brake refresh is likely imminent. The offside rear wheel distortion advisory also warrants a spin check for kerb damage or a cracked rim. Suspension wear is present but not yet critical. The offside front lower suspension arm rear inner bush has been worn but not excessively in both 2026 tests, and the offside rear anti-roll bar linkage ball joint was excessively worn in March 2025. That joint may have been replaced before the 2026 test since it does not reappear, but the front bush wear suggests the car has not had a comprehensive suspension overhaul. Headlamp aim was out in both March 2026 and March 2025, which could simply reflect bulb replacement without realignment or could point to a weak headlamp levelling system. The nearside rear stop lamp lens has been cracked across three consecutive tests, a minor electrical cosmetic issue that has been tolerated rather than fixed. Overall, the car appears to have been kept running without significant neglect, but the accumulation of corrosion, worn brake components, and persistent suspension advisories indicates a vehicle that has been maintained to a pass standard rather than a preventative one.
