2015 Volkswagen California 2.0L Diesel · AW15 AAJ

The most recent MOT on 21 May 2026 was a pass, but it carried several advisories – the near‑side and off‑side rear tyres are close to the legal tread limit and show edge wear, there is a minor oil leak that is not deemed excessive, and the central rear exhaust is corroding. Over the last six years the pattern has moved from occasional minor advisories to more serious failures, notably the fractured rear coil springs in 2024 and a front tyre cut in 2023, before being rectified for the latest pass. The recurrence of tyre‑wear warnings, oil‑leak notes and exhaust corrosion indicates a maintenance trend that is currently deteriorating rather than stabilising, even though the vehicle has cleared its most recent test. At 134,870 mi for a 2015 model the average annual mileage is roughly 12,300 mi, which is above the typical UK average of about 8‑10 000 mi per year. This level of use suggests the suspension components, bushings, shock absorbers and drivetrain have been subjected to considerable cyclic loading, accelerating wear on bearings, joints and seals. Higher mileage also means the brake pads and discs are likely approaching the end of their service life, and the engine and transmission fluids may have exceeded their time‑based service intervals, regardless of the recorded mileage. Potentially the vehicle has seen relatively continuous use rather than long periods of storage, which can exacerbate wear on moving parts. When you inspect the car, pay particular attention to the rear suspension. Verify that the rear coil springs have been replaced – look for even ride height, no sagging rear corners and a solid “thump” rather than a rattling noise when the rear wheels are pushed upward. The front and rear shock absorbers have been flagged for light oil misting on several occasions; examine the shock bodies for any wetness or oil stains and test the damping by applying firm pressure on each corner – the car should settle smoothly without excessive bounce. Tyre wear is now close to the legal minimum on all four wheels, with edge and inner‑edge wear patterns that often point to mis‑alignment, worn camber settings or deteriorating rear bushings; a full wheel‑alignment check and a visual inspection of the front suspension arms, ball joints and bushings are advisable before committing. The oil leak, while not excessive, should be located – common sources on a VW are the valve‑cover gasket or oil filter housing; monitor the oil level over a few days and look for fresh oil spots under the chassis. Finally, the corroded central rear exhaust should be examined for perforations, rust flakes and compromised mounting brackets, as a breach can increase emissions and, in extreme cases, present a fire hazard. Beyond the specific MOT items, treat the vehicle as a high‑mileage, eleven‑year‑old model. Check the 12‑volt battery for cranking voltage and any signs of sulfation, especially if the car has spent periods idle. Inspect the brake discs for surface rust, scoring or uneven wear that could cause shudder under braking, and verify that the pads have sufficient thickness. Examine all fluid reservoirs – engine oil, coolant, brake and power‑steering fluids – for colour, clarity and appropriate levels, and consider a full service if the last recorded oil change predates the mileage. A thorough test drive should reveal any suspension clunks over bumps, steering pull, brake pulsation or unusual engine noises that would hint at internal wear. If these checks are satisfactory and any pending tyre replacement or suspension work is priced reasonably, the car can be a viable purchase, but the buyer should budget for imminent tyre set‑up, potential shock or spring refurbishment, and a comprehensive service to address the oil leak and exhaust corrosion.
