2004 Audi A4 1.8L Petrol · DL04 UBH

As a 1.8-litre petrol engine from 2004, this Audi A4 sits in a higher tax bracket than modern equivalents. Fuel economy will be modest by contemporary standards, especially if the engine is not running at peak efficiency due to the exhaust and sensor issues noted in its history.

Maintenance costs are the primary concern here. Given the recurring brake binding and suspension wear, you should budget significantly more than the average for an older saloon. Expect an annual running cost in the region of £1,500–£2,000, factoring in fuel, insurance, and the high probability of needing urgent mechanical repairs before the next MOT.

Focus your inspection on the braking system. The history shows repeated issues with binding brakes, leaking calipers, and hoses. Ensure the car stops straight and that there are no warning lights (specifically ABS) on the dashboard during a test drive. Check the condition of the headlamp lenses, which have been flagged for light output issues multiple times, and verify that all exterior lights are fully functional.

Beneath the car, look for signs of the previously noted sub-frame corrosion and check the suspension components for play or knocking sounds. Finally, check the battery tray to ensure the battery is securely mounted, as this has been a recurring minor fault. Given the history of oil leaks, inspect the engine bay and the ground where the car has been parked for any fresh fluid patches.
