My 164Q keeps blowing the engine services fuse. Does not blow every time though. It seems to be when I turn hard left or right. I read on this forum that it could the fuel pump, evap canister solenoid or motronic relay. I climbed under the car and found on the left side a wire harness that had fallen down and rubbed through on the cv boot. The two white wires were bare and the black was completely broken.The harness has 2 white high temp wires (silicone or teflon) and a black wire. The whole harness is covered in some sort of heat braiding. I fixed this all up but am not sure if this has solved the problem. What is this harness for?
Thanks:confused:

Yes, I believe that to be the 3 wire O2 sensor cables. It doesn't sound like that would make a fuse blow though...

Yes, the fuse can blow because one of the black wires is the 12v power to the O2 heater. 12V to a ground will do bad things.
