2011 Audi A4 2.0L Diesel · MDJ 3W

A clear pattern of deteriorating suspension and braking components defines the roadworthiness history of this 2011 Audi A4, with two separate MOT failures within a single calendar year triggered by fractured coil springs and a serious anti-lock braking system fault. The most recent attempt on 31 January 2026 produced a pass, but only after a near-miss the day before when an offside rear coil spring was recorded as fractured or broken, a Major category defect that would have rendered the car non-roadworthy. The earlier 2025 test followed a near-identical sequence, with a nearside front coil spring fracture causing a first failure and a clean pass recorded on the retest the same day. Taken alongside the 2024 failure for an ABS warning lamp, an inoperative engine management indicator, and a Dangerous defect on the secondary parking brake actuator, the record suggests a vehicle now sitting at a high mileage threshold where structural and electronic faults are beginning to surface with greater frequency. The trend across the last three years is not one of stable roadworthiness but of progressively serious defects, even when the final paperwork shows a pass. With 189,138 miles recorded on a car of approximately fifteen years of age, the annual accumulation works out at around 12,609 miles per year, which sits well above the typical average for a vehicle of this vintage. MOT coverage is continuous from 2022 through to early 2026 with no extended lay-up gaps, indicating the car has remained in regular active service rather than being stored for long periods, and the mileage progression between tests is consistent with steady daily use. Mechanically, this level of sustained use places considerable cumulative stress on the coil springs, dampers, brake discs, suspension arms and flexible components such as engine mounts and bushings, all of which are visible in the advisories logged over the four-year DVSA window. The high annual mileage also helps to explain the 2024 ABS and engine management lamp failures, as wiring looms, wheel speed sensors and electronic actuators on a high-mileage Audi of this generation are vulnerable to fatigue and moisture ingress. For a prospective buyer, the immediate priority is a focused inspection of the suspension, because fractured coil springs have appeared on both the nearside front and offside rear within a twelve-month window. On a test drive, listen for clonking or rattling noises from the front end over uneven surfaces, particularly at low speed over speed humps, and pay attention to any visible sagging or uneven ride height at the corners. Check the remaining springs carefully for surface rust pitting or hairline cracks near the lower coils, and have the front suspension arms and anti-roll bar drop links inspected for wear, as slight ball joint play was flagged in 2023. The brake system also warrants close attention: with a fluctuating service brake recorded in 2024, pitted front discs noted in 2023 and a parking brake actuator failure on the same test, the car should be road-tested from cold to confirm straight-line stability under firm braking, no warning lamps on the dashboard, and a firm, consistent pedal without excessive travel. The oil leak advisory carried on both the 2026 failure and pass warrants a thorough under-bonnet inspection with the engine warm, looking for fresh seepage around the cam chain tensioner, valve cover gasket and turbo oil feed lines, all of which are known wear points on high-mileage Audi A4 petrol and diesel engines of this era. The nearside front inner tyre edge wear flagged in 2026 suggests a possible tracking or suspension geometry issue, so the wheel alignment should be checked and the inner shoulders of both front tyres examined for feathering. Finally, given the 2024 ABS fault, confirm that the warning lamp extinguishes promptly on ignition and that the system cycles correctly during a low-speed stop, and ask for evidence that the secondary parking brake actuator has been properly replaced rather than simply reset, as a Dangerous failure on this component is not a defect to take lightly on a car approaching 190,000 miles.
