i got an error message from the dash so i ordered an oil pressure sender
from bma. took it to the mech and he replaced it. still got the error.
told him to fix it...the wire coming from the car has 2 pins the sender
bma sent me has 1 pin. the alldata tech sheet for a 91 535i shows a
1 pin OilPSender. what do u guys have? we tried connecting the two
and grounding each one but still the compy throw the dash error. only when
u turn the car off though =[
