2004 Audi A4 1.9L Diesel · LL53 GCF

The most recent MOT test on the 2004 Audi A4 occurred on 2026-04-18, resulting in a passing outcome with a single minor defect related to the offside registration plate lamp and two advisories concerning the rear brake system. Despite the presence of these advisories—particularly the deteriorated rear brake hoses and worn, pitted brake discs—the overall maintenance trend over the past five years appears relatively stable, with no repeated failures or critical issues beyond the noted wear and tear typical of high-mileage vehicles. The absence of major defects in the intervening clean MOTs suggests that while the vehicle has endured some mechanical stress, the maintenance regime has generally been adequate to prevent catastrophic failures, though routine attention to the brake system and suspension components remains prudent. The vehicle’s recorded mileage of 199,670 miles at the time of this assessment represents a reasonable annual usage rate of approximately 9,076 miles, which aligns closely with the expected wear pattern for a 22-year-old car. This level of mileage is consistent with moderate to heavy use, particularly given the significant age of the vehicle, and indicates that the car has likely been subjected to regular driving conditions rather than prolonged periods of inactivity. The presence of a failed MOT in 2022, which included dangerous conditions such as near-side rear brake pads below the legal minimum thickness and excessive binding in the service brake system, underscores the importance of addressing wear-related issues promptly to prevent further deterioration or safety risks. For a prospective buyer, the most critical areas to inspect during a physical examination and test drive are the brake system, suspension, and drivetrain components, given the recurring advisories and past failures. Focus on the rear brake hoses, which show signs of deterioration; visually inspect for cracks, bulges, or leaks and listen for any signs of pulsation or excessive noise during braking. The worn brake discs should be checked for warping, scoring, or excessive thickness loss, and the calipers should be examined for binding or excessive play, which could indicate internal wear or seized components. During the test drive, monitor for uneven brake pedal travel, a spongy or vibrating pedal feel, or any grinding noises when applying the brakes, as these symptoms may indicate further degradation of the rear brake system. Additionally, the near-side rear brake pads being below the legal minimum thickness—now corrected but previously a dangerous failure—reminds buyers to prioritise brake maintenance to avoid future compliance issues. Beyond the mechanical checks, the vehicle’s high mileage and age warrant thorough attention to consumable items and structural integrity. Given the recorded corrosion advisories on the rear sub-frame and coil spring mountings, visually inspect these areas for signs of rust penetration, particularly around wheel arches, exhaust systems, and undercarriage components, as standing water and road salt accelerate corrosion over time. The engine mountings, which were noted as damaged but not excessively perished, should be checked for excessive movement or noise, as this could lead to vibration transmission or premature wear on other components. For fluid systems, consider a calendar-based service check for the engine oil, transmission fluid, and brake fluid, as these can degrade over time even without mileage accumulation. Finally, verify the condition of the offside front drive shaft CV boot, which failed in 2025, by inspecting for leaks or excessive wear around the boot seals, and listen for unusual noises from the rear axle during acceleration or cornering, as these could indicate further internal damage. A comprehensive inspection of the tyre tread depth, sidewall integrity, and alignment will also be essential, given the previous advisories on tyre wear patterns and the risk of sidewall cracking from prolonged exposure to road elements.
