2018 Audi A3 2.0L Petrol · H10 PBR

Brake wear is the dominant mechanical theme in this A3's recorded history, with the September 2024 test resulting in a failure on dangerous rear brake pad readings less than 1.5 mm thick at both nearside and offside positions, alongside matching front tyre edge wear advisories that had already been flagged the day before the retest passed. The September 2025 pass then recorded front inner brake pads wearing thin and a coolant level below minimum, suggesting that braking components and routine fluid checks remain areas where deterioration is advancing between tests rather than holding steady. The intervening 2022 and 2023 passes were clean with no defects recorded, but the appearance of dangerous brake pad wear in 2024 followed by renewed brake and coolant advisories a year later indicates an ongoing consumable wear pattern rather than an isolated incident. The recorded mileage of 37,751 miles over eight years equates to roughly 4,719 miles annually, which is low for the vehicle's age and consistent with predominantly short-trip, light-load use. Such accumulation rates typically produce less wear on drivetrain and major suspension components than higher-mileage counterparts, but they can also accelerate certain issues through infrequent use, such as brake disc corrosion from prolonged damp exposure, coolant stagnation, and standing-based deterioration of rubber seals and bushes. The mileage history shows no gaps in annual testing since 2022, and there is no evidence of long periods off the road, though the relatively static annual mileage implies the vehicle is in regular but modest use. For a prospective buyer, the immediate priorities are the braking system and cooling circuit given their recent advisory history. With rear brake pads having worn to a dangerous level at the 2024 test and front inner pads now noted as wearing thin, the rear discs should be inspected for lipping and scored surfaces, and the calipers checked for binding or uneven sliding that may be accelerating inner pad wear on the front axle. The brake pedal should be tested for excessive travel or a spongy feel, and a standing brake application from around 30 mph should produce a straight, firm pull without judder through the steering. The coolant reading below minimum at the 2025 test warrants checking for fresh staining at the radiator, expansion tank, water pump area, and along the length of any visible coolant hoses, as well as confirming the level is correct and the cap is sealing under pressure before purchase. Additional inspection points arise from the recurring front tyre edge wear advisories in 2024, which point to a possible geometry or suspension geometry issue rather than simple tread consumption. On a test drive, listen for clonking or knocking from the front suspension over speed humps and uneven surfaces, and feel for vague steering, tramlining on cambers, or uneven pull under braking that could indicate worn control arm bushes, tie rod ends, or top mount deterioration. The rear registration plate deterioration advisory is cosmetic, but it is worth confirming the underlying panel is not showing rust bubbling around the mounting area, which can be an early sign of corrosion on this generation of A3. Finally, given the low annual mileage, verify recent service records for oil and filter changes, and inspect the underside for any surface rust or oil misting consistent with a vehicle that completes many short journeys from cold.
