2004 Audi A4 1.8L Petrol · LS04 JHA

The most recent MOT test on the 2004 Audi A4 occurred on 2022-12-16, resulting in a passing grade with several persistent advisories that reflect ongoing but not critical issues. While the vehicle has not failed an MOT since 2018, the pattern of recurring corrosion-related advisories—particularly in the suspension subframe and rear suspension spring mountings—indicates a gradual but consistent wear progression in structural components. The presence of multiple oil leaks and deteriorated brake hoses also suggests that maintenance may have been delayed in some areas, though the advisories themselves do not yet pose immediate safety risks. The fact that the vehicle passed in 2022 despite these advisories implies that the owner has likely addressed the more severe issues (such as the broken coil spring in 2018) and is now managing the wear more effectively, though vigilance remains necessary. The recorded mileage of 137,010 miles for a vehicle aged approximately 22 years represents a reasonable annual usage rate of around 6,228 miles per year, which is typical for its age and likely reflects a combination of regular driving and periods of storage. Lower mileage could indicate lighter use or extended periods the vehicle was not in service, while higher mileage would have accelerated wear on consumables like brakes, tyres, and fluids. Given the consistent advisories related to suspension and fluid degradation, it is plausible that the vehicle has undergone some form of maintenance to mitigate wear, but the lack of recent service history in the MOT records suggests that the owner may not have fully addressed all issues—particularly the persistent oil leaks and brake hose deterioration. The differential axle leak and CV joint boot failure from 2019 also highlight the importance of monitoring drivetrain components, as these can lead to increased wear or even catastrophic failure if ignored. For a prospective buyer, the most critical areas to inspect during a physical examination include the suspension and drivetrain, as these have shown recurring issues. On a test drive, listen for unusual noises such as clunks or rattles from the suspension, particularly around the front and rear lower arms, which may indicate excessive play in ball joints or worn bushings. Check for uneven tyre wear patterns, which could suggest misalignment or suspension misalignment, and inspect the tyres closely for sidewall damage or cracking, as this can be a precursor to blowouts or structural failure. The brake system should be tested for performance, including checking for brake shudder or pulsation, which could indicate warped discs or binding calipers. Inspect the exhaust system for leaks, as minor leaks can lead to increased emissions and potential structural damage. Additionally, visually confirm that the oil leaks are contained and not causing excessive contamination under the vehicle’s floor mat, as this could indicate a failing seal or gasket. Given the vehicle’s age and the history of corrosion advisories in the subframe and suspension components, it is advisable to verify the structural integrity of these areas, particularly if the vehicle has been stored for extended periods. Check for signs of rust penetration into critical areas, such as the rear subframe or suspension mounts, as this can compromise the vehicle’s handling and safety. The brake hoses, which have been noted as slightly deteriorated in multiple MOTs, should be replaced if they appear brittle or cracked, as they can fail suddenly and lead to brake failure. The oil leaks should be addressed promptly to prevent further contamination of the drivetrain and engine components. Lastly, since the vehicle has not been serviced for fluid changes in recent years, consider checking the condition of the engine oil, transmission fluid, and brake fluid, as these fluids degrade over time and can affect performance and safety. A thorough inspection of the battery, including its terminals and overall health, is also recommended, especially if the vehicle has been stored for long periods, as corrosion or a failing battery can lead to starting issues or electrical problems.
