2017 Audi A4 2.0L Diesel · CP67 BCF

The 2017 Audi A4 currently holds no valid MOT after failing its most recent test on 2 January 2026 at 145,363 miles. The maintenance trend is clearly worsening. A vehicle that sailed through its 2020 test with zero defects now presents a cluster of serious mechanical and structural failures. The tester flagged a fractured offside rear coil spring, rear brake pads worn down to the wear indicator, and both front lower suspension arm bushes worn. An engine management light that was either on or inoperative, combined with an oil leak, points to unresolved powertrain issues. This is not a car that has been carefully maintained through its high-mileage years. The mileage accumulation tells a clear story. Between November 2020 at 57,080 miles and November 2021 at 69,856 miles, the car covered roughly 12,776 miles in a year. That pace accelerated sharply. By December 2022 it had reached 89,384 miles, and by December 2023 it sat at 107,946 miles. Then came a dramatic surge: 37,417 miles added in just over two years between the December 2023 test and the January 2026 failure. Annual use jumped well above the 16,151-mile average, placing sustained stress on every wearing component. The gap between the December 2023 pass and the January 2026 failure is short, yet the car accumulated enormous mileage in that window with no recorded interim attention. A buyer inspecting this car in person should focus on the rear suspension first. The fractured offside rear coil spring is a critical failure that compromises ride height, handling, and tyre wear. The rear brake pads were at the wear indicator, so the discs and calipers need close examination for scoring or binding. Both front lower suspension arm bushes were flagged as worn, and at this mileage the entire front suspension linkage, including ball joints and track rod ends, warrants a thorough check. The oil leak, though described as not excessive, should be traced to its source, as Audi engines of this era are known for issues with camshaft housing gaskets and piston ring wear at higher mileages. The engine management light fault demands a full diagnostic scan rather than a simple code clear. Corrosion also deserves attention. The 2021 test noted corroded rear coil spring mountings on both sides. On a car now covering 145,363 miles, that corrosion may have progressed to structural weakness, particularly around subframes and suspension mounting points. The advisories on front brake disc wear appearing in both 2022 and 2023 suggest a pattern of deferred brake maintenance that likely continued unchecked. This vehicle has been driven hard and serviced reactively. Any purchase should be contingent on a full independent inspection, a diagnostic readout of the engine management system, and a detailed underbody examination for corrosion and suspension integrity.
