2008 Audi A4 2.0L Diesel · DS08 DVT

A 2008 Audi A4 with 143,332 miles on the clock carries a mixed mechanical history, with the most recent MOT on 5 December 2025 revealing both a pass and a fail recorded on the same date. The failure items are the most pressing: both front drive shaft CV boots were found to be split or insecure to the point that dirt ingress was no longer prevented, and the horn was non-compliant. These are not minor advisories, and a prospective buyer should treat the CV boot defects as an immediate rectification job, since continued driving with compromised boots leads to rapid grease loss, contamination of the constant velocity joint, and ultimately joint failure with associated vibration or loss of drive. The advisories recorded at the same test, namely an oil leak not considered excessive, slight underbody corrosion, and tyres perishing, suggest an older vehicle where age-related deterioration is beginning to manifest across multiple areas simultaneously. The vehicle has covered an average of approximately 7,963 miles per year over its eighteen-year life, which is broadly typical for a car of this age and suggests steady rather than intensive use. There are no extended gaps in testing history that would indicate long periods off the road, and the testing frequency of annual visits from 2022 onwards is consistent with regular road use. The mileage accumulation appears steady, which generally correlates with consistent wear on consumables rather than the heavy single-trip accumulations that can stress drivetrain components. The presence of MOT tests every year from 2022 through 2025, with no multi-year absences, means the components have been subjected to ongoing observation and the recorded defects reflect a vehicle that has been in active service throughout. The advisories recorded across the 2023 and 2025 tests provide specific mechanical priorities for a prospective buyer to investigate. The 2023 test flagged light oil misting on the nearside rear shock absorber, thin rear brake pads on both sides, worn and pitted front brake discs on both sides, worn upper suspension arm pins or bushes on both sides at the rear, and slight play in the nearside front lower suspension arm ball joint. On a test drive, listen for clonks or knocking from the front suspension over speed humps and uneven road surfaces, particularly on the nearside where the ball joint play was noted, and feel for vagueness or imprecise steering response. The front brake discs, which were already pitted or scored in 2023, will almost certainly have deteriorated further by now, so test for brake judder under firm pedal application and check for any grinding or pulsing through the steering wheel. The 2025 advisories for an oil leak and slight underbody corrosion should be inspected on a ramp or with the vehicle raised, paying particular attention to the engine sump, oil filter housing, and any areas where surface rust could be masking more significant structural corrosion, particularly around subframe mounting points and suspension turret areas. The 2022 advisory regarding damaged front tyre sidewalls and the 2025 advisory for tyres perishing confirm that the vehicle is now in an age bracket where rubber components require close attention, and a thorough inspection of all four tyres for cracking, sidewall bulges, and uneven wear is essential. The 2024 failure for incompatible headlamp light sources, a non-working rear fog lamp, a partially failed rear position lamp, and a missing central rear seat belt buckle are safety-related items that must be verified as properly resolved before purchase. Buyers should confirm that the seat belt buckle has been correctly refitted or replaced, that headlamp bulbs are of the correct specification, and that the rear fog lamp is operational. The pattern of suspension wear across multiple advisories, combined with the 2022 anti-roll bar linkage failure, indicates that the front and rear suspension overhaul cycle is approaching, and budgeting for replacement of the upper suspension arms, bushes, and potentially the anti-roll bar linkages should be factored into any purchase decision.
