Hi guys I have a 2009 Audi a5 3.0 V6 Quattro diesel with 94000 miles. Recently the engine light has come on and has stayed on continually. The car is running the exact same as before, I've had the codes read and have attached pictures. Can anyone advise me of what may or may not be the issue. Much appreciated thanks

Hopefully that is just an intake manifold flap actuator rod that requires replacement. Very easy to change and a common fault.
Bank 2 is the RHS as you stand at the front of the car looking at the engine, although I would replace both of the arms they aren't difficult to change and wear in the other one will probably throw a code at some point in the future.

Thanks mate, you was spot on. When i checked the metal clip had broken and the rod wasn't connect so replaced the part and the engine emissions light has gone off. Thanks again appreciate it.
