Hi all,
can anyone tell me what the 404 relays run. I have 2 of them first one says DWP-H and the second says DWP-V, next to the relays. The only reason I’m asking is I had an issue with my Audi A3 1.9tdi not starting due to an electrical problem. It wasn’t cranking , no sound from the fuel pump etc. Got it checked and fuses 1-4 inside the car were not getting the correct ampige which was bringing up many fault codes
