Our Verdict
Proceed with caution and budget for imme
When inspecting this specific Audi, prioritise a thorough check of the braking system and tyre condition. The most recent failure in February 2026 was due to thin front brake pads and illegal tyre tread depths, so ensure these have been replaced with quality parts rather than just 'patched up'.
Ask the seller for evidence of the work carried out following the February 2026 failure. You should also check the ABS system specifically; the 2026 failure noted an ABS warning lamp, which indicates an electronic or sensor fault that must be confirmed as rectified. Finally, check the condition of all four tyres, as the 2025 history shows a tendency for tyres to be worn close to the legal limit or perishing.
As a 1.9L diesel, this Audi A4 is likely to offer relatively efficient fuel economy for its age, making it suitable for longer motorway journeys. However, potential buyers should check the specific tax band and insurance group, as these can vary based on the exact engine output.
Maintenance costs for a vehicle of this age and mileage will include regular servicing of the diesel engine and potential replacements for suspension components, which are noted as common failure points for this model aggregate. Expect typical maintenance costs to include periodic brake disc and pad replacements and tyre changes.
Focus heavily on the braking and tyre components. The MOT history for ND04AGU shows repeated issues with tyre tread depth and cracking/perishing (seen in both 2025 and 2026). Inspect the sidewalls of all tyres for cracks and ensure the tread depth is well above the 1.6mm legal limit.
Crucially, investigate the ABS system. The February 2026 failure explicitly mentioned an ABS warning lamp. You should check that this lamp extinguishes upon starting the engine and that the ABS system functions correctly during a test drive. Additionally, given that coil springs and suspension arms are common failure points for the Audi A4 model aggregate, listen for any knocks or clunks when driving over uneven surfaces.
This 2004 silver Audi A4 diesel has covered 101,151 miles as of February 2026. The MOT history reveals a pattern of maintenance needs, specifically regarding tyre tread depth and brake wear. While the 2024 test showed no defects, the subsequent tests in 2025 and 2026 both involved failures related to consumable items like tyres and brake pads.
Aggregate data for this model shows an 80.8% MOT pass rate, with common failures often relating to coil springs, windscreen wipers, and suspension arms.

- Multitronic CVT FailureSerious
The CVT can judder, flare or lose drive entirely. It is generally less reliable than the Tiptronic or manual alternatives.
- 1.8T Timing Belt / Water Pump FailureSerious
The 1.8T engine uses a timing belt that can fail if intervals are not maintained, destroying the engine. The plastic water pump impeller can also strip.
- Oil Sludge BuildupSerious
The 1.8T engine is prone to oil sludge if servicing has been neglected, blocking the oil pickup and starving the engine of lubrication.
