2013 Audi RS4 4.2L Petrol · AJ13 CTV

A car with seven recorded test events and only one outright failure presents a roadworthiness profile dominated by isolated tyre issues rather than systemic mechanical deterioration. The 2026-07-18 pass is the latest in a generally stable run of clean results dating back to 2022, interrupted only by the 2021 dangerous tyre failure and a modest front brake disc advisory in 2025. Notably absent from the record are any advisories relating to corrosion, exhaust integrity, suspension linkages, or structural components, which is a relevant observation for a thirteen-year-old performance vehicle expected to show some degree of chassis wear. The single advisory for front brake disc wear in 2025, described as not excessive, is the only brake-related note in the entire history, suggesting the braking system has not been a recurring source of concern across the testing period. With 101,017 miles accumulated over thirteen years, the annual rate of approximately 7,771 miles is broadly typical for a car of this vintage, indicating steady rather than exceptional use. The testing record shows consistent annual attendance from 2020 onwards, with no prolonged gaps that would suggest extended off-road storage, and the mileage progression between tests appears to be incremental rather than featuring any unusual spikes or stagnation. For a high-performance saloon such as the RS4, this moderate usage pattern is mechanically relevant because the 4.2-litre naturally aspirated V8, carbon-fibre driveshaft, and dynamic ride control components are engineered for sustained high-load operation; consistent rather than sporadic use tends to be less damaging than very low annual mileage combined with irregular short trips. The absence of mileage gaps also means there is no evidence of long-term lay-up that could have introduced issues such as seized calipers, perished rubber, or fluid degradation, although the single 2021 test event recorded just one day before a retest pass indicates a prompt remedy following the dangerous tyre defect. For a prospective buyer, the most relevant physical checks concentrate on the areas that have previously shown minor wear. The 2020 advisories for light oil misting on both front shock absorbers warrant close inspection of the front suspension for any progression to visible fluid leakage, weeping around the strut bodies, or uneven tyre wear patterns that could indicate damping compromise. The front brake discs flagged in 2025 should be examined for lipping, scoring, and current thickness, ideally with a measurement taken to confirm remaining service life. On a test drive, particular attention should be paid to any knocking or clonking from the front suspension over uneven surfaces, which could indicate worn top mounts, control arm bushes, or anti-roll bar links, as well as any pulling under braking that might suggest a binding caliper or warped disc, both plausible given the recorded disc wear. The 2021 failure related to an exposed ply on the offside front tyre and a deep cut to the offside rear tyre is worth contextualising rather than dismissing, as tyres in this condition typically result from either impact damage or prolonged use beyond the legal tread threshold. A physical inspection should include a thorough check of all four tyres plus the spare for age-related sidewall cracking, uneven shoulder wear, and DOT date stamp verification, as performance tyres on an RS4 can degrade significantly even with adequate tread remaining. Beyond the recorded items, given the mileage and age, the underside of the vehicle warrants close scrutiny for any developing corrosion on the subframe, suspension arms, and brake pipe routing, areas not necessarily captured by routine MOT testing. A mechanical inspection by a specialist familiar with the B8 RS4 platform would be prudent to assess the clutch, carbon-fibre propshaft, and rear differential, none of which fall under standard MOT scope.
