2023 Audi A5 S Line 40 Tfsi Mhev S-A 2.0L Petrol · RA23 ACU

The latest DVSA MOT test on the 2023 Audi A5 S Line 40 TFSI MHEV S-A recorded a passing outcome, but this follows a previous failure in July 2026, indicating a concerning maintenance trend. The front shock absorber fluid leak and tyre wear issues from the failed test have not been rectified, suggesting either unresolved mechanical problems or inadequate servicing between MOTs. The advisory of rear shock absorber misting—while not failing the vehicle—signifies progressive wear, particularly in the dampers, which could escalate into a major defect if not addressed promptly. The presence of a minor tyre cut, though not severe enough to reach the ply, warrants monitoring, as such damage can compromise tyre integrity over time, especially with the noted edge wear nearing legal limits. This pattern raises red flags for potential underlying suspension or alignment issues that may require immediate professional attention to prevent further deterioration. The recorded mileage of 26,470 miles for a vehicle aged three years represents a reasonable annual usage rate of approximately 8,823 miles, which is typical for a car of this age and class. However, the absence of a service history or clear maintenance records between the two MOTs—spanning just over a month—could indicate either infrequent use or a lack of proactive maintenance, both of which can accelerate wear on critical components. Higher mileage generally correlates with increased stress on suspension elements, brake systems, and drivetrain consumables, but the specific fluid leak and tyre wear issues suggest that the vehicle has either been driven under demanding conditions or has not been serviced adequately to mitigate wear. The rapid progression of defects between MOTs also hints at either poor maintenance discipline or underlying mechanical inefficiencies that need addressing. Given the recurring MOT advisories and defects, the prospective buyer must prioritise a thorough mechanical inspection before purchase. Focus on the front and rear suspension, particularly the shock absorbers, which show signs of fluid loss and misting. Listen for irregular suspension noises during the test drive, such as clunking or rattling, especially when driving over bumps or at higher speeds, as these may indicate failing dampers or damaged suspension bushes. Inspect the front tyres for uneven wear patterns, which could signal misalignment or camber issues, and check for any signs of excessive heat damage or tread separation. The front shock absorber fluid leak is critical; a professional should assess whether the damper is beyond repair or if a replacement is necessary to prevent further failure. Additionally, verify the brake system for signs of binding calipers, corrosion on discs, or excessive heat discolouration, as the vehicle’s age and usage may have contributed to these issues. For the buyer, the next steps should include a comprehensive physical inspection of the vehicle’s standing condition, given the potential for corrosion and fluid degradation over time. Check the battery terminals for corrosion or loose connections, as a failing 12V system can exacerbate electrical issues and affect the MHEV drivetrain’s efficiency. Inspect the exhaust system for leaks or structural integrity, particularly around the catalytic converter and muffler, as emissions-related failures can lead to costly repairs. Finally, since the vehicle has not been serviced between MOTs, the buyer should request service records to confirm the last oil change, tyre rotation, and fluid top-ups, as these are essential for maintaining the MHEV hybrid system’s longevity. If possible, arrange for a pre-purchase inspection by a qualified mechanic to confirm the severity of the suspension defects and ensure the vehicle’s roadworthiness and reliability.
