The Audi faults that actually come through the workshop door — what causes them, the order to test in, and what an honest independent garage should charge.
These are the Audi faults we see most often in the workshop, each with the real cause on Audi engines, the order to test in, and an honest independent-garage cost rather than a dealer estimate.
Audi problems explained
- Audi 2.0 TDI Loss of Power — Loss of power on Audi 2.0 TDI is overwhelmingly the famous P2015 intake manifold flap fault, a blocked EGR/DPF, or a split boost pipe. Always check the cheap stuff first — a £15 hose can mimic a £700 turbo fault.
Symptoms overlap between makes, but the likely cause does not. Knowing which component fails first on a Audi is what stops good parts being replaced on guesswork — always pay for the diagnosis before you pay for parts.
