2003 Audi A4 1.9L Diesel · YG03 ADL

The Audi A4 has maintained a consistent MOT history with no defects recorded across five consecutive tests, most recently passing on 3 August 2025 at 175,713 miles. This suggests the vehicle has undergone regular servicing and passed all statutory inspections without major failings. The most recent test was conducted just over a year ago, which is within the acceptable window for a used-car purchase, though buyers should verify recent servicing beyond the MOT scope. The absence of advisories or recurring faults implies the previous owner adhered to basic maintenance, though critical components like suspension bushes, coil springs, and brake calipers remain at risk due to the vehicle’s age and mileage. Mileage accumulation averages approximately 7,640 miles annually, a rate typical for a car of this age. The intervals between tests are consistent, with no unusual gaps or spikes in usage—each MOT was conducted roughly 12 months apart, aligning with the legal requirement. This pattern indicates stable ownership without prolonged periods of neglect or rapid wear. However, the lack of service records beyond MOTs means critical fluid changes (e.g., timing belt, differential oil) may not have been documented, leaving potential hidden failures unaddressed. Given the vehicle’s age and mileage, an in-person inspection should prioritise the suspension system, particularly rear bushes and coil springs, which are prone to fatigue and corrosion at this stage. The brakes, including rear binding calipers and front disc wear, should be checked for uneven pad thickness or warping, as high-mileage Audi models often develop uneven braking. Structural integrity, especially around wheel arches and sills, must be examined for corrosion, as the 2003 model year is susceptible to rust progression. Finally, verify the exhaust system for leaks or excessive corrosion, particularly around flanges, as this is a common failure point in older Audi models.
