2006 Audi A4 4.2L Petrol · OV56 ABO

The most recent DVSA MOT test for this 2006 Audi A4 was conducted on 16 April 2026 and resulted in a pass with no defects or advisories recorded, which represents a stable and compliant current roadworthiness position. The prior test on 6 March 2026 also passed cleanly, and a further pass on 25 October 2025 and 11 October 2024 confirms a consistent pattern of compliance over the last two years. However, it is worth noting that a failure was recorded on 4 March 2026 for an excessively worn offside suspension rod ball joint, classified as a major defect. The fact that a pass was issued only two days later on 6 March 2026 strongly suggests the component was repaired or replaced and the vehicle subsequently re-presented, rather than the defect being overlooked. Overall, the maintenance trend appears stable rather than deteriorating, though the suspension intervention indicates that front-end wear items have begun to demand attention on this now twenty-year-old chassis. With 89,306 miles recorded over approximately twenty years, this A4 has covered around 4,465 miles annually, which is considerably below average and indicative of either light regular use or extended periods of standing. Such low annual mileage is mechanically significant because many wear-related failures on vehicles of this age are driven more by calendar age and environmental exposure than by mileage accumulation. Rubber components, fluids, gaskets, and electrical items degrade with time irrespective of use, while prolonged standing can introduce its own problems such as brake disc corrosion, seized or binding calipers, and dry crankcase seals developing leaks upon recommissioning. Given the sparse and clean recent MOT history combined with the low mileage profile, a prospective buyer should prioritise age-related inspections rather than expecting obvious high-mileage wear symptoms. Tyres should be examined closely for sidewall perishing and cracking, as rubber deteriorates with age even when tread depth remains legal, and any tyres over six years old should be replaced regardless of wear. The 12V battery should be load-tested, since a battery older than five or six years is likely near the end of its service life and can fail without warning. Brake discs should be inspected for surface corrosion and the calipers checked for binding, particularly if the vehicle has stood for long periods, and a firm pedal with no juddering under braking should be confirmed on a test drive. Fluid services should be verified regardless of recorded service history, as brake fluid should be renewed every two years, coolant on a similar or manufacturer-specified cycle, and the timing belt replacement interval confirmed if applicable to the engine variant fitted. During a road test, particular attention should be paid to the front suspension, given the recent ball joint failure. Listen and feel for any clunks, knocking, or vagueness through the steering when traversing bumps or over uneven surfaces, and check for uneven front tyre wear which would indicate misalignment or worn suspension components beyond what was replaced. Steering response should be precise without excess play, and the vehicle should track straight without pulling. Beneath the vehicle, inspect for fluid leaks from the engine, transmission, and differential, examine exhaust mounts and hangers for deterioration, and check all undertray fixings. Finally, verify that the ignition coil packs, timing chain stretch (if fitted), and turbocharger actuator (if a turbocharged variant) have been addressed, as these are known concerns on this generation of Audi A4 and may not surface on an MOT but represent significant upcoming expenditure.
