Hi-
I'm new to the forum & Audi ownership. I appreciate any input.
I have a 2008 A8 4.2V8. Recently had 55K service after 9K miles my engine light popped on. After driving a bit it began flashing and the idle and ride at low speeds was rough.
I contacted my mechanic and he advised not driving. I used my Ross-Tech CAN and got some faults in the engine. As listed below.

My mechanic thought it might have been a cylinder coil and replaced without success. Now he is considering a fuel injector issue. Can anyone help in decifering these codes and offer some direction?

Thanks in advance
