Hey, I was having problems with my 2009 A5 burning oil and coolant and decided to just rebuild the engine for the sake of it. CAHA 2.0 TDI quattro with a manual transmission. Engine is rebuilt and in the car now, fires up and runs good but i have some trouble with a few codes and faults. it started with the coolant temp sensor not reading anything, then my check engine light came on and it said low oil level. So I drained the oil and it was the right amount(because there is no dipstick and it didnt read any oil on the on board computer). reading codes through my Carly it was registering it had oil. Only real code is P0522 Engine control unit. this code shows up under ABS System, AC and Parking brake. On the engine it reads P011800 Engine coolant temp circ. high output.
I am suspecting the ECU or some connection to it...
I have been dealing with this for a week now and everything looks fine really. have anybody any theories/experiences that can help me? I am thankful for any advise right now
Picture for attention
