2020 Audi A4 2.0L Petrol · WR20 ENC

A persistent tyre pressure monitoring system warning has been recorded at three consecutive MOT tests, with the advisory first appearing in 2024 and carrying through unchanged to the May 2026 pass. That recurrence, alongside repeated front tyre wear advisories and a deteriorating rear number plate, defines the mechanical character of this A4. The most recent test on 26 May 2026 produced a pass with no failures, and the vehicle has actually recorded only two minor defects across its entire testing history, so the structure of the record is one of consistent roadworthiness at test level. However, the clustered advisories suggest a car that is otherwise compliant but is developing a cluster of small, sensor-related and consumable concerns typical of an executive saloon approaching mid-life. At 57,092 miles over six years, the A4 is accumulating roughly 9,500 miles annually, a rate that is unremarkable for a vehicle of this class and age. There are no significant gaps in the testing record and no sudden jumps in mileage between samples, which points to continuous rather than intermittent use. That kind of steady accumulation is generally kinder to cold-start components, battery life, and seal condition than a low-mileage profile with long standing periods, but it does mean that wear items such as front brake discs, pads, tyres, and suspension bushes will be accumulating real working fatigue. The front tyres specifically have been flagged for inner-edge wear on two occasions, which warrants close attention even though only one formal advisory appears in 2026. For a buyer, the TPMS warning is the most concrete area to investigate. The light being illuminated at three successive tests could indicate a single faulty sensor, a slow leak from a wheel, or stored pressure values that the system has not been reset from, and the specific cause should be diagnosed with the vehicle in the shop rather than dismissed as a dashboard nuisance. The inner-edge tyre wear flagged in 2024 is also worth a second look, because uneven shoulder wear on the front axle is frequently symptomatic of worn suspension components rather than simply alignment drift, and on an A4 of this generation it commonly traces to tie rod ends, wishbone bushes, or top mount bearings. On a test drive, listen for clonks or knocks over uneven surfaces, particularly from the front end, and pay attention to any vagueness or wandering from the steering wheel that was not present when the car was new. Brake feel is another area worth probing during inspection. While no brake-related advisories have been recorded, the front tyres are consistently flagged first, which on a front-driven A4 often correlates with calipers that are beginning to bind or pistons that are sticking slightly, pulling uneven pad material onto the discs. On the road, feel for any pulling to one side under firm braking, any judder through the pedal, and any grinding or scraping that suggests pad material has worn prematurely. The minor windscreen wiper defects from 2023 are unlikely to be relevant now, but the chipped windscreen noted in 2025 should be checked for any propagation, as stone chips in the driver's primary vision area can fail a future test. Finally, the deteriorated rear plate should be replaced before the next MOT, and the tyres themselves warrant a physical inspection given the repeated advisories, as the legal minimum is not the same as having useful tread life remaining.
