Hey!
I have an Audi A6 2.4 -2007 that misfires, there is no difference whether it is cold or hot.
I have connected it to an OBD2 reader and received the following fault codes:
P0056 - HO2S Heater Control Circuit Bank 2 Sensor 2
P0304 - Cylinder 4 Misfire Detected
P0301 - Cylinder 1 Misfire Detected
I've changed all ignition coils, spark plugs, lambda probes,
and swapped seats on the ignition coils to see if the problem moves .. But it doesn't, Still the same fault codes.
Does anyone have a idea what is causing the problem?
