2015 Audi A4 2.0L Diesel · LP15 NEU

A chronic wear pattern has emerged at the rear nearside suspension, where the most recent test on 27 October 2025 flagged movement in the lower arm bush that, while not yet at failure level, represents the first advisory item on this vehicle's MOT record after four years of clean passes. Prior to this, the only recorded defect was a major failure on 10 October 2024 for a split constant velocity boot on the nearside front outer drive shaft joint, which was rectified to enable a pass the following day. The overall trajectory is one of generally sound roadworthiness punctuated by two isolated mechanical issues affecting different axles and systems, with the rear suspension bush now warranting close attention as it approaches the threshold of becoming a failure item. With 68,781 miles recorded over an eleven-year lifespan, this A4 has covered roughly 6,250 miles annually, placing it squarely within the expected band for a vehicle of its age and avoiding both the accelerated wear associated with high-mileage use and the corrosion risks linked to under-driven examples. The mileage progression across the five recorded tests is consistent and incremental, with no significant gaps in testing that would suggest extended periods off the road. This steady, moderate accumulation tends to produce even wear across consumables such as brakes, tyres, and suspension components rather than the localised fatigue seen on high-mileage cars, though it does not eliminate the need to inspect age-related degradation on rubber and polymer items. For a prospective buyer, the priority inspection areas should mirror the exact components flagged in the MOT history. On a test drive, listen for any clonking or knocking from the rear suspension, particularly over speed bumps, uneven road surfaces, or during direction changes, as further deterioration of the nearside rear lower arm bush could now be transmitting noise or vibration into the cabin. Pay attention to steering feel and any shudder through the wheel under acceleration or when turning at full lock, since the recently rectified CV boot failure on the nearside front driveshaft should be visually examined for fresh grease loss around the joint and felt for any vibration that would suggest the boot has split a second time or that the joint itself has been contaminated and is wearing prematurely. Also inspect the surrounding area of the inner CV joint for any signs of grease spray on the underside of the wheel arch or suspension arm. Beyond the flagged items, a thorough physical inspection should include a careful look at the general condition of the rear suspension assembly, including the coil springs for any signs of corrosion or sagging, the rear shock absorbers for leaks, and the anti-roll bar drop links and bushes for play, given that the lower arm bush advisory suggests the surrounding components may also be approaching their service interval. Examine the underside of the vehicle, particularly around the subframe mounting points, exhaust hangers, and brake pipes, for any corrosion that could become a future advisories or failure item on an eleven-year-old premium vehicle. Finally, check the nearside front driveshaft gaiters visually on a ramp or by turning the steering to full lock, confirm there is no grease contamination on the inner rim or behind the wheel, and ensure the recent repair has not left any unsecured clips or torn rubber that could reappear at the next test.
