2018 Audi A4 2.0L Diesel · VN18 TJO

The most recent MOT recorded on 21 May 2021 was passed, but it carried four advisories concerning thin front and rear brake pads and front and rear tyres that were close to the legal tread limit or worn on the edges. No outright failures were noted, indicating the vehicle was mechanically sound at the time, yet the presence of multiple wear advisories suggests consumables were nearing the end of their service life. With no subsequent MOT entries supplied for the intervening years, a definitive trend cannot be plotted, but the last available data points to a maintenance pattern that was beginning to require attention rather than showing improvement. At eight years old and 56,789 miles on the clock, the car averages roughly 7,100 miles per year, which sits comfortably within the typical UK usage envelope. This mileage does not imply excessive wear, but it does mean that wear items such as brake discs, pads, suspension bushings and tyre rubber have been exposed to a substantial number of load cycles. If the vehicle has spent extended periods standing still between trips, certain components—particularly the brake discs and calipers—may have suffered from corrosion or uneven pad deposition, while tyres can deteriorate from age even if tread depth remains acceptable. When you inspect the car, give particular focus to the braking system. Verify that the front and rear pads have been replaced since the 2021 advisory; excessive pedal travel, a pulsating brake pedal, or squealing noises under moderate braking can indicate worn pads or glazed discs. Examine the brake discs for scoring, rust patches or uneven thickness, and check that the caliper pistons move freely without binding. The tyres should be inspected for both tread depth and sidewall condition; even if the tread appears adequate, rubber over six years old can develop dry rot, leading to cracking or hardening that compromises grip, especially in wet weather. Look for uneven wear patterns that might reveal misaligned suspension or worn steering components, and listen for clunking or knocking when the car is driven over bumps, which could signal deteriorated bushings or worn ball joints. Beyond the immediate wear items, a thorough buyer’s check should include the 12‑volt battery, which at eight years may be approaching the end of its service life; a load test or voltage check under load will reveal its capacity. Verify that the engine oil, coolant and brake fluid have been changed at the manufacturer‑recommended intervals, as time‑based degradation can lead to reduced lubrication and corrosion. Inspect the under‑carriage for any signs of rust, especially around the rear subframe and suspension mounting points, which can be exacerbated by prolonged stationary periods. Finally, confirm that a full service history exists, with stamps for oil changes, timing belt or chain service (if applicable), and any major component replacements, as this documentation will give you confidence that the vehicle has been maintained in line with Audi’s specifications.
