Open up the wiring harness. There is a Blue wire that goes to the dash. I had a car where that wire was melted and grounding off causing major problems.....
LOL I would take a test light, ground it, and touch another ground and it would light up.......I was like WTF.
I had to run a new wire from the altenator to the fuse box, then to the dash.
Took me 3 alternator rebuilts to fiqure this out....POS 318i. Each time it was blow the altenator. First i thought it was a bad altenator cus it stoped chargeing like 10mins after i hooked it up. After it blew the 2nd one I found the melted wire. Im not sure if its the same on the eta but u never know
