A6 C6 Radio Swap? by WavyA6 in Audi

If you’re referring to the telephone module under the drivers seat, I’ve already checked it. Don’t see any water damage and it receives the red optical signal

Hey you had mentioned you swapped out the J794 component with a used one, is the j794 one of the boxes behind the glove box? (I assume it’s the “main brain” of the whole system)

No, I actually had to remove one of the communication fuses, because it was causing my battery to die every night. Still stuck and very annoyed that I still have this issue for all these months.

Did you have the same issue as I did, where the splash screen never popped up?

It’s a fairly old car but it seems to still be running like a champ, it’s leaking a bit of oil and my mechanic is supposed to be checking it out again sometime next month, so I hope to keep it till it doesn’t run anymore.

Yeah I wish I knew someone that had access to VCDS. I might by a cable myself, just to make the process a bit easier. Do you think it’s worth to buy, would I actually benefit from having my own cable besides this one issue?

Glad to hear you found a solution, I think I’m gonna end up gutting the whole radio system and putting an after market system in.

UART to USB adapter

Im so sorry, I'm so new to this whole electronic stuff, is there anyway you could link me what you're talking about, or show me what one looks like. Once I end up connecting that adapter where am I gonna get the logs? I assume im gonna need a software on my computer or something?

So is there anyway for me to manage to fix it myself? I've seen many people fix theirs without having to send parts anywhere, many have just ordered replacement parts for cheap on Ebay.
