Audi A4 - buyer's guide
How much is a Audi A4 worth?
Used Audi A4 prices start from around £1,000 at UK dealers, with models ranging from 2000 to 2026. The exact value depends on the variant, year, mileage and condition - a high-spec S Line will be worth significantly more than a base model with the same age and miles.

Part-exchange, trade, or private sale - what's the difference?
The same A4 can be worth three different amounts depending on how you sell it:
- Private sale - typically the highest price, but you handle viewings, tyre-kickers and paperwork yourself
- Part-exchange - convenient when buying your next car, but dealers will offer below market rate to build in their margin
- Trade sale - quickest route to cash, but usually the lowest offer
Our free estimate tool shows what similar cars are listed for at dealers right now - a solid starting point whichever route you choose.
What problems should I look for on a Audi A4?

- Oil pump drive hex bolt failure (B7) (dangerous)
- Cam follower failure from HPFP (B7) (dangerous)
- Multitronic CVT gearbox failure (B7) (dangerous)

Can I check the service history of a Audi A4?
Yes. Our service history check pulls official records directly from Audi's manufacturer database, showing:
- Every recorded service - dates, mileage and dealer location
- Work carried out at each visit
- Gaps in the service schedule that could affect value
If you're buying a used A4, this is one of the most important checks you can do. A full service history typically adds 10-15% to a car's value.
How are these estimates calculated?
We crawl thousands of UK dealer websites daily and record what they're actually listing cars for. When you enter a reg, we match your car's exact variant, age and mileage against current and recent listings to produce an estimate grounded in real market data - not inflated book values or outdated guides.
