I have an S4 and due to the car being so low, I hit the bump and the smashed the O2 sensor. Now, the car is throwing codes for every single sensor that you can possibly imagine is in the engine bay. Can anyone help me find or tell me where I can get a good deal on an ECU.
P.S- It's a 2000 S4 Quattro.

 

sounds like the o2 lines shorted out.
replace the wires/ o2 sensor
check the fuses.
don't buy an ecu.
