EPC ON, p0341, p2279, p0299, p2187 codes all come on at once. Cam bridge scree Issue?
I have an 2010 Audi A4 2.0l B8 engine. Alot of work has already been done on car like timing chain replacement, ignition coils, and some other stupid stuff before me trying to fix this issue. The car will sometimes stall and it squeals like the serpentine belt is loose or tensioner isn't working. When the car stalls briefly or stutters the EPC light comes on and cel codes pop up ranging from p0341 , p2187, p2279 and p0299. All these come on at once even though engine will quickly start running relatively smooth again after EPC light cuts off(which doesn't even come on for more than a second). I am also going to list all my symptoms. I believe my possibilities is it being the cam bridge and at this point i have no other possibilities. Some solid help and not guessing would be great.
SYMPTOMS
1.EPC Light comes on and then car will misfre, stutter or cutoff when this happens.
2.CEL Light comes on at same time as EPC light coming on and registers these codes. p0341(camshaft sensor), p02187(system lean), p2279(intake air leak), p0299(turbo underboost).
3.Car squeals when hitting gas like serpentine belt is very loose or tensioner isn't working right. Tensioner has belt replaced and i am not 100 percent sure this is even related to issue.
4.Sometimes there are misfire cylinder codes accompanied wiht other codes. But not all the time and cylinders only misfire when this EPC comes on and everything else happens.
POSSIBLE SOLUTIONS
1. Cam bridge Cover. The screen specifically ahs been knocked out and is causing problems. PLus the newer design has a better upper neck for proper movement ive read .
2. BAD VVT solenoid?
QUESTIONS
1. AM assuming if it is cam bridge i should also inspect the exhaust camshaft for scoring. Right?
2. What else could it possibly be?
3. VVT could cause this **** too imo but wouldn't i jsut get a code for that?
