Our Verdict
Walk away unless the price is exceptiona
Given that this A8 is over two decades old, any purchase needs to be approached with caution regardless of MOT outcome. The 2022 MOT failure included a 'likely to become detached' suspension arm defect, which is a serious safety issue and would be costly to repair on a luxury saloon with air suspension — budget £500 to £1,500 depending on the component. The dual headlamp aim failures suggest the headlight adjusters or mounting points may have worn out, which on a 2003 A8 often points to age-related plastic deterioration. Insist on seeing any service history, particularly evidence of cambelt changes (the 4.2 V8 has timing chains but ancillary belts still need attention), coolant and transmission fluid changes, and any air suspension work. Negotiate hard on price and factor in at least £1,000 to £2,000 of immediate remedial work based on the MOT history alone.
When viewing, check that all four headlamps are correctly aligned and that the headlight adjusters are intact, as the MOT record shows both sides failed on the same test. Inspect all four tyres carefully — the MOT caught both rear tyres below 1.6mm, which is dangerous and suggests the car may have been left standing for long periods. Examine the front suspension for play, knocking noises, or uneven tyre wear, as the upper suspension arm failure suggests worn bushes or ball joints. Also worth checking on a 4.2 A8 of this age: the auto gearbox for smooth changes, the MMI system for function (older units are known for pixel failures), and the air suspension for slow raising or sagging corners.
Running a 4.2-litre petrol Audi A8 from 2003 is expensive by modern standards. Real-world fuel economy is likely to be in the high teens to low twenties mpg, meaning fuel costs alone could easily exceed £2,500 per year if you cover 8,000 miles. Road tax for a vehicle of this age and engine size sits in the higher brackets, and insurance will be costly as this is a large, powerful luxury saloon in a high insurance group. Parts are pricier than for mainstream saloons, with OEM components and even pattern parts commanding a premium. Expect annual maintenance including tyres, brakes, and routine servicing to run into four figures, and budget additional reserves given the age-related failures already evident in the MOT history. Overall, realistic annual running costs including fuel, tax, insurance, and maintenance are likely to be in the region of £3,500 to £4,500.
Given the specific MOT failure pattern on this vehicle, prioritise inspecting the front upper suspension arms on both sides for any play, damaged bushes, or signs of previous welding repairs — the nearside was flagged as 'likely to become detached' which is a serious structural concern. Check the headlamp mounting points and adjusters on both sides, as both headlights failed the aim test on the same day, suggesting either worn adjusters or a mounting issue. Inspect all four tyres for age-cracking as well as tread depth, since two tyres failed for tread depth simultaneously and this can indicate prolonged storage without rotation.
Beyond the MOT-specific items, this generation A8 4.2 (D2 platform, 2003 model year) is known for age-related issues with the air suspension compressor, valve block, and air struts — listen for the compressor running excessively when starting and check for sagging overnight. The 4.2 V8 is generally robust but check for oil leaks from the cam chain covers, valley gasket, and rear main seal. The automatic gearbox (typically a ZF 5HP24) should be tested in all modes including reverse, and any hesitation or flare between gears is a red flag. Finally, check the electrics thoroughly — the older MMI infotainment system, window regulators, and central locking are all known weak points on cars of this age.
This AK53WSX is a 4.2-litre petrol Audi A8 first registered in October 2003, finished in blue. Only two MOT tests appear in the history, and the vehicle failed one of them on the same day it passed another test, with serious defects including a suspension arm likely to become detached. The 96,476 miles recorded is consistent with the model's average annual mileage of 8,126, putting it broadly in line with expectations. However, the combination of a structural failure item, two tyre failures, and two headlamp aim failures in a single test raises concerns about how the car has been stored and maintained.
Across 13,825 Audi A8 vehicles analysed, the model shows an 89.0% MOT pass rate, with the most common failure reasons being tyres, headlamp issues, and suspension arm wear — all three of which appeared on this specific vehicle's failure record.

Historical MOT pass rates and DVLA records for 2003 model year cars.
- Air Suspension Strut and Compressor FailureSerious
The full air suspension on all four corners inevitably develops leaks as the rubber air bellows age, eventually killing the WABCO compressor.
- Multitronic CVT Gearbox IssuesSerious
The Multitronic CVT gearbox can judder, flare, or lose drive if fluid changes were skipped or the gearbox ECU starts to fail.
- Electrical Module FailuresModerate
Ageing electronics cause multiple module failures, including keyless entry antennas, comfort modules, and CAN bus communication faults.
