2019 Audi A4 Technik 35 TDI S-A 2.0L Diesel · LL69 KBJ

The latest MOT test for the 2019 Audi A4 Technik 35 TDI S-A recorded a passing result on 2026-01-21, though it included a single advisory regarding the offside front brake disc showing signs of wear, pitting, or scoring without being critically compromised. This follows a pattern of consistent MOT results since 2023, with only one failure noted in 2024—specifically for rear coil spring mountings that were severely corroded and weakened. The failure in 2025 highlighted ongoing thinness of both front and rear brake pads, which suggests a gradual but persistent wear trend in braking components. While the recent tests have not repeated these failures, the presence of advisories on brake discs and pads indicates that the braking system is approaching or exceeding its operational limits, warranting closer attention to prevent potential failure points. The vehicle’s recorded mileage of 90,455 miles over approximately seven years represents an annual usage rate of around 12,922 miles, which is notably high for a car of this age and model. Such mileage accumulation typically accelerates wear on critical components like suspension bushes, brake pads, and drivetrain elements, as well as fluid degradation over time. The absence of significant mileage gaps suggests either heavy or frequent use, which can exacerbate issues such as corrosion in suspension mountings, uneven tyre wear patterns, and potential fluid leakage from seals or hoses. The recent MOT failure on coil spring mountings further underscores the importance of addressing corrosion early, as it can lead to catastrophic failure if left unchecked, compromising structural integrity and ride quality. For the prospective buyer, the most critical areas to inspect immediately are the braking system and suspension components. The advisories on the front brake discs—particularly the offside unit—should prompt a visual and tactile check for any signs of warping, excessive heat discolouration, or binding during braking. Listen for any unusual noises such as grinding when applying the brakes, which could indicate worn pads or damaged discs. The thinness of the front and rear brake pads, as recorded in previous MOTs, suggests they may need replacement soon, potentially within the next 5,000 to 10,000 miles, depending on driving conditions. Test the brakes on a drive to assess for any shuddering, pulsation, or reduced stopping power, which could signal warped discs or internal brake issues. Additionally, the severe corrosion of the rear coil spring mountings, as documented in the 2024 MOT failure, demands immediate attention. Visually inspect the rear suspension for any signs of rust, cracks, or deformation in the mounting brackets, and listen for clunking or rattling noises when driving over bumps or uneven surfaces. The suspension should be checked for uneven ride height, excessive play in the steering, or binding in the wheel bearings, as these could indicate failing components. Given the high mileage, also verify the condition of the front suspension bushes and control arm bushings, as these wear out over time and can lead to clunking noises or poor handling. Finally, check the tyre tread depth and sidewall condition for signs of cracking or perishing, which can compromise tyre safety and structural integrity, especially with the vehicle’s age. Ensure all fluids—brake fluid, coolant, and engine oil—are topped up and free from contamination, as fluid degradation accelerates with age and high mileage.
