2013 Audi A4 1.8L Petrol · LG63 FEX

The most recent MOT test on 17 October 2025 resulted in a pass, which on the surface is reassuring, however the same date followed immediately on from a failed test the day prior on 16 October 2025 where the vehicle was recorded with a dangerous defect for front tyre tread depth below the 1.6mm legal limit on both fronts. This dangerous classification means the tyres were considered an immediate risk, and the fact that the vehicle passed just a day later strongly suggests replacement tyres were fitted in between, rather than the underlying cause resolving itself. When assessing the longer term trend, the history shows a fairly consistent pass rate since 2020, but the volume of advisories has been creeping over the past three cycles, with suspension component wear noted in 2023, rear tyre wear advisories in 2024, and anti-roll bar linkage play flagged alongside a windscreen defect in 2025. The overall trajectory suggests a vehicle that is being maintained to a passable level but where consumable and chassis components are starting to demand more frequent attention, consistent with a thirteen year old car nearing the end of its suspension bushes' natural service life. At 102,964 recorded miles over approximately 13 years, the annual usage equates to roughly 7,920 miles per year, which sits comfortably within the typical band for a privately owned executive saloon of this age. The mileage progression appears steady and uniform across the MOT records with no evidence of significant standing periods or implausibly rapid accumulation, which is a positive indicator that the vehicle has been in regular use rather than left dormant for extended stretches. Regular usage of this nature is generally beneficial for mechanical health as it prevents issues associated with prolonged standing such as seized brake calipers, flat-spotted tyres, perished rubber seals, and oil starvation in the turbocharger or engine from infrequent warm-up cycles. However, the cumulative mileage is now substantial, and for a 2013 Audi A4 particularly those fitted with the common 2.0 TDI engine, items such as the dual mass flywheel, clutch, timing belt service interval verification, turbocharger actuator, and EGR valve should be considered wear items given the distance covered. With regard to the specific defects and advisories recorded, the front tyre dangerous failure warrants close attention during any inspection. Even if new tyres have been fitted, the buyer should confirm the brand, age marking, and that all four tyres are of matching specification, as uneven mixing on an Audi with quattro or front wheel drive electronic stability systems can affect handling. The anti-roll bar linkage ball joint play noted on the offside front should be inspected for any worsening clunking or knocking over speed bumps and uneven road surfaces, as this component is a known wear item on the B8 A4 platform and will eventually require replacement alongside related suspension bushes. The 2023 advisory regarding front lower arm rear bushes showing wear but not yet excessive movement is a precursor worth monitoring, as these bushes progressively deteriorate and typically cost several hundred pounds per side to replace once they begin allowing noticeable movement. The recurring nearside and offside rear tyre wear on edges observed in 2020 and 2024 could suggest tracking misalignment or worn rear suspension components, and a four-wheel alignment check would be prudent during the test drive to confirm there is no uneven wear developing on the inside or outside shoulders. Beyond the recorded advisories, a thirteen year old Audi A4 with this mileage profile demands scrutiny of several age related service items regardless of MOT outcome. The timing belt replacement interval is critical on the 2.0 TDI engine and should be verified as having been carried out within the manufacturer specified mileage or age window, as failure can result in catastrophic engine damage. Brake discs on a vehicle of this age commonly exhibit lipping and corrosion around the outer edges, and caliper slide pins may have begun to seize, particularly if the car has seen any mixed urban and motorway use. The 12V battery should be load tested as units of this vintage frequently hold surface charge but fail under demand, and the cooling system including the radiator, water pump, and thermostat housing is a known weak point on this generation. On the test drive, listen for any timing chain rattle from cold on start-up which would suggest the chain tensioner requires attention, check for excessive smoke from the exhaust indicating turbo or EGR wear, and inspect the underside for any oil leaks from the sump, cam chain cover, or front crankshaft seal. Finally, verify all service book stamps or digital service history entries match the recorded mileage and confirm that the longlife oil change intervals have not been exceeded, as extended drain periods on TDI engines accelerate injector and turbocharger wear.
