Audi A4 1.8T 2012 Start-stop fault then the EPC light and engine light.I replace the battery but after that only the engine light came on. It is shacking when idling but not too bad.

SOURCE: EPC Light.

change the EPC sensor, it will cost you only 100$

SOURCE: check engine light and epc

I have an 03' 1.8 T GTI with just over 100k. EPC and Check engine light was on... got it fixed it was the Engine Speed Sensor cost $450.00 to fix!!!!!!!!!!!!!!

SOURCE: audi tt 180 quattro car wont start. EPC and E-M system lights on

I would suggest you check oil levels etc. Generally these cars suffer from the air mass meter / air sensor problems aswell as coil problems too. Did you ever get a solution to the problem?

You will need a scan tool, or just drive the car and if it was due to battery once the computer finishes running its diagnose checks it will turn light off, this may take a week and some driving around. you could also have the computer scanned to see what code is stored and see if its due to the battery.
