I'm so stupid sometimes....Yesterday, fucking around with relay K7, i manage to open it to see inside that relay, little job since it just a tiny yello plastic cover....Seem's like new, so i put the plastic cover back....BIG MISTAKE.......There all my problems started, but it was unoticeable, the car was just like regular, but when i put that crappy cover back, i didn't notice that inside, there a little plastic edge, and put on the opposite side, it manage to put the relay on OPEN position...So it drain the battery overnight....YES,,,,A BIG mistake from me, but well, aren't wee all learn that way?....
So.....If you ever have any questions about electric, my girlfriend is here to help you...lolll ...And she a super babe too...loll...I think i'll mary her, or first issue, as long as i got my bimmer....
Long life to all....
