2006 Audi A4 2.0L Diesel · G19 GAM

The most recent DVSA MOT, dated 19 November 2025, resulted in a failure. The test flagged a dangerous condition on the nearside front tyre, where tread depth was below the legal 1.6 mm limit, and a structural bulge on the off‑side front tyre, both of which constitute immediate safety concerns. In addition, the central stop lamp was recorded as non‑functional. Earlier MOTs show a pattern of escalating issues: brake pad wear and disc corrosion were noted in 2024, a binding nearside front service brake in 2023, and fractured rear coil springs in 2022. The progression from advisory‑level wear to major safety‑critical failures indicates a worsening maintenance trend rather than a stabilising one. The recorded mileage of 84,146 mi over a twenty‑year lifespan averages roughly 4,200 mi per year, which is considerably below the typical UK usage of 10‑12 000 mi annually. Such low annual mileage often points to periods of extended inactivity or limited use, rather than continuous moderate running. While reduced wear on engine and drivetrain components can be a benefit, prolonged storage can accelerate rubber ageing, corrosion of brake components, and deterioration of seals and fluids. Any sudden spikes in mileage that are not reflected in the MOT log would warrant scrutiny for undocumented wear. A prospective buyer should give priority to the front tyre condition: inspect both front tyres for tread depth, sidewall integrity, and any signs of separation or bulging; replace them immediately if the defects noted in the MOT persist. Verify that the central stop lamp is operational and that the wiring harness is intact, as a missing stop signal is a legal and safety breach. The brake system requires a thorough examination – the thin front and rear pads, pitted discs, and reported binding on the nearside front service brake suggest that the pads may soon be below minimum thickness and the discs could be nearing the end of their service life. A full brake service, including pad replacement, disc resurfacing or replacement, and a bleed of the hydraulic system, is advisable before the vehicle is driven regularly. The fractured rear coil springs recorded in 2022 should be checked for proper replacement; any residual play or uneven rear ride could indicate lingering suspension issues that affect handling and tyre wear. Beyond the specific defects, the car’s age and low‑usage profile demand age‑related inspections. Examine the tyre sidewalls for cracking, dry rot, or hardening, as rubber can degrade even on low‑mileage tyres. Inspect the chassis, suspension mounting points, and under‑body for rust, especially if the vehicle has been stored outdoors or in a damp environment. Test the 12 V battery voltage and load capacity, as batteries lose charge over time when not cycled. Verify that the coolant, brake fluid, and engine oil have been changed at appropriate intervals – fluid colour, smell, and the presence of moisture can indicate the need for a complete service. Finally, confirm that the service book contains stamps or receipts matching the mileage and that any major repairs, such as the coil‑spring replacements, are documented, giving confidence that the vehicle has been maintained to a roadworthy standard.
