Frequently asked questions
Is an ECU remap required after fitting?
Yes, following installation, the engine software must be remapped to suppress fault codes and ensure optimum engine calibration.
Why does this Downpipe have a flexible hose?
The flexible hose acts as a vibration-damping element between the turbo and the rest of the exhaust system, which extends the service life of the connections.
Does this part fit the SQ5?
The SQ5 has a different engine (TFSI petrol); this Downpipe is specifically designed for the Q5 8R with the 3.0 TDI Biturbo diesel engine.
