B7 AUDI A4 Electrical Problems

[neptune42]

My audi A4 has been having electrical problems in which it turns on a nd drives normally and everything but things like the power window, headlights, signals, and other stuff do not function. I am here asking if anyone has experienced this or knows the cause. I have switched the control module, but that was not it.

dam nobody know so far, i searched everywhere to find the cause but nothing so far. The vehicle has 54k miles

You’ll need to find a good wiring diagram to use. Figure out what isn’t getting power and trace to the source of its voltage.
Could be a bad relay perhaps working intermittently or a thermal fuse opening up. I am pretty new at these cars but fixed my share of electrical issues. Scan for codes too. Sorry but all I got for ya.

Yes, get a diagram, find ground wires, confirm grounds are good. You might even add your own grounds.
