Hello all I'm new here!
I just had a few questions about my 2004 a4 1.8t. Well first off my 219 relay went due to water in the ecu compartment. I replaced that and sucked all the water out, which fixed my radiator fan issue.

Then I replaced the battery on the car because it was the original one. I had troubles starting after that but eventually got it going and ran fine n started fine for about a month.

Now the car is doing what it did when I replaced the battery which is when I turn the key I get nothing. I'm going to check the voltage at the starter when I checked it before I was getting about .8 volts.

My question is what voltage should I be getting? Also could this be some other problem I'm not thinking of?

Thanx for any and all input!
