2006 B7 A4 2.0T quattro 240k miles. Third owner.

Vian,
Typically when multiple codes appear there is a singular fault somewhere that is settling off other codes, (sympathetic cascade phenomenon) some even in unrelated segments of the monitored components.
Try resetting the codes. Then operate the vehicle and watch carefully which codes appear first. This may give you a clue as to what the primary fault is.
It could be something as simple as a blown fuse or as complicated as a bare wire grounding out intermittently.
Good luck and post back what you find.

Edit: has anything on the car been serviced or repaired recently? If yes look to that area first.

Hi thank you for the reply so yes when i just bought thr car from the guy i replaced the 4 spark plugs because it misfired on 2 , i took it to a mechanic after that and they deep cleaned all the injectors and it was brought to my attention injector 2 and 3 are only working 40 and 60% after the clean so we replaced them all are working 100% now


but there was a massive oil leak , it was around almost a 2L coke bottle on the ground from the turbo so took it to the mechanic and he told me that its the turbo thats leaking and gave me all those error codes


the Abs and EPS or whatever thats called im not sure since this is my first real car and brake light warning stays on when driving
