2004 Audi A4 1.8L Petrol · GU04 AAV

A 22 year old Audi A4 presenting an MOT history largely free of recorded advisories, yet with a curious anomaly worth flagging immediately: a pair of test attempts recorded on consecutive days in both 2023 and 2025, each sequence consisting of a fail followed immediately by a pass on the next day. With no defects listed against either failure, this pattern strongly suggests minor rectify-on-station items (such as a bulb replacement, tyre top-up, or a quick adjustment) rather than serious mechanical defects, but a prospective buyer should still request sight of any rectification paperwork to confirm what was actually addressed. The most recent test outcome on 18 February 2025 was a pass with no advisories recorded, and the broader trend across four tests over the last three years shows consistent roadworthiness at the point of examination, with no corrosion, component wear, or brake-related issues flagged by the examining station. Mileage on this A4 stands at 193,469 miles accumulated over approximately 22 years of use, equating to a typical annual accumulation of around 8,800 miles per year. This figure sits comfortably within the expected range for a vehicle of this age and is consistent with regular mixed driving rather than either long-term storage or exceptionally high commercial use. There are no significant gaps between recorded tests that would suggest extended periods off the road, and no anomalies in the testing frequency, which has been maintained at roughly annual intervals. Mechanically, this usage profile implies steady but moderate wear on the major drivetrain and chassis consumables: the engine, manual or automatic transmission (whichever is fitted), clutch assembly, turbocharger if applicable, and suspension components will all have accumulated substantial working hours, but at a rate that is not unusually aggressive for the age of the car. Given the age and mileage, the buyer should prioritise a thorough inspection of the areas commonly affected on high-mileage B7 platform A4s. Suspension components warrant particular attention, including the front control arm bushes, wishbone rear bushes, anti-roll bar drop links, and coil springs, all of which can exhibit play or cracking on test drive via knocking over uneven surfaces, wandering steering, or clonking from the front end over speed humps. The multi-link rear suspension is also prone to failing bushes that produce rear-end instability, particularly under cornering load. On the test drive, listen for any clonking or creaking from the front and rear suspension, feel for vagueness or looseness in the steering, and check for uneven tyre wear which can indicate geometry issues or worn suspension linkages. The braking system, whilst not flagged in the recent MOT record, should be inspected thoroughly given the mileage, with particular attention to brake disc condition (look for lipping and scoring), caliper slide pins for binding, and the flexible brake pipes which on older A4s can perish and crack under the wheel arches. The 2.0 TFSI petrol engine, if fitted, is known for oil consumption issues and timing chain stretch, so oil level should be checked cold and a listen for chain rattle on cold start is worthwhile. Diesel variants should be checked for injector leak-back, EGR valve operation, and turbo actuator wear. On the road, watch for any smoke from the exhaust on startup or under load, listen for any unusual engine rattles, and confirm that the clutch (if manual) takes up smoothly without slipping or juddering. Finally, inspect the underside and wheel arches carefully for corrosion on the subframe, suspension arms, and brake line routing points, as these areas can deteriorate on a vehicle of this age regardless of MOT-recorded advisories.
