I’ve been having issues with my Audi a4 for two months. After much diagnosing I narrowed the issue down to the steering control module. Grabbed one from the scrapyard and installed. Still same issue no horn, airbag, steering controls etc. Then when I have that 10amp fuse plugged in the climate control doesn’t work. When I pull it all is normal. Do I need to program this module? I’m so frustrated with this car. I’ll add the errors I got after replacing the module.

Thanks

You’ve got a couple of low voltage messages there, I’d be looking at that. Faulty earth? Corroded connection?

I’ve looked at about ten grounds thus far. I’ll have to keep looking for more. I also have a voltage drain from that cable that connects to the positive terminal. I know it goes to the alternator do you know if it connects to the ignition switch?

No I’m not sure of that. I can send some wiring diagrams if that helps.

Yeah if you can I’m gonna look some up now. But I’ll send a picture of what I’m referring to. Again appreciate the help.
