Audi A4 B8/B8.5 (2008–2016): common problems and is it worth buying?
The B8 and B8.5 A4 is refined but maintenance-sensitive: keep on top of oil services or the engine will punish you. Bought with a clear service record it is a classy, capable car; bought blind it can be a money pit.
Strengths
- Refined, quiet ride
- Strong Quattro grip in winter
- Good residual value
Weak points and common problems
- 2.0 TFSI oil consumption on early EA888 Gen 2 engines
- Multitronic CVT issues on front-wheel-drive pre-2014 cars
- Timing-chain tensioner on the 2.0 TFSI
Maintenance by mileage
- Timing-chain tensioner if 2.0 TFSI EA888 Gen 2
- Oil-consumption test
- Haldex oil on Quattro
- DSG oil service
Suggested checks. Real intervals depend on the engine, equipment and how the car was used.
Is it worth buying?
Yes, if it is a documented car with the right engine history. A 2.0 TFSI with the tensioner sorted and no oil-burning, or a TDI Quattro with full service, is a fine buy. Avoid early oil-burners and FWD Multitronic cars without history.
Frequently asked questions
Is the Audi A4 B8 reliable?
It can be, but it is sensitive to maintenance. The known risks are 2.0 TFSI oil consumption, the timing-chain tensioner and the Multitronic CVT. A documented car avoids most trouble.
What are common Audi A4 B8 problems?
Oil consumption on early 2.0 TFSI EA888 Gen 2 engines, timing-chain tensioner wear, and Multitronic CVT faults on FWD pre-2014 models.
Which Audi A4 engine should I buy?
A later TFSI with the tensioner updated and no oil burning, or a TDI with Quattro and full history, are the safer choices. Check the plate to confirm the car's record.
