So I bought a 2003 B6 A4 1.8. I knowingly bought the car as is.

No power at all (Its not the Battery)
No dash lights, no crank, no start, no clicking.

ECU looks to have been water damaged (confirmed dead, plenum chamber...). Would the ECU affect ALL power to the vehicle? Im assuming yes, though I've never owned any sort of German vehicle. (Jeep guy )

Hoping a "new" ECU, and maybe some relays, will do the trick. I have already looked into the ECU complications with VIN, Immo, SKC, etc. That should not be a problem, just hoping its just the ECU. Anyone have any suggestions, or been in a similar boat?

Thanks.
