2001 a4 1.8t Quattro fuse 34 blown

[RichLu]

Wondering how to solve my blown fuse 34 which I believe controls the fuel injection. While I switched my ect today I checked the coil pack wiring and taped up any area with wire exposed. Now I am also seeing the connection on cylinder 2 cracked but engine is running fine just like for the fuse issue to be solved.

Bump anyone? I know it's fuel injection -timing related.

Possibly a short to ground in the coil wiring harness causing that fuse to blow, i would look online to see what source voltage should be and and check voltage drop, if its a bad wire then thats the issue or short to ground that could be if neither, just replace fuse and see if that fixes it... could just have been old or needed replacement

Fuse 34? That provides power to the N112, N80, N75, leak detection pump, MAF, primary 02 sensor heater, and secondary 02 sensor heater. If you've replaced the fuse with the proper size (15 AMP) and the fuse is still blowing, check the wiring for each of those components.
