OBC

Post Wed Mar 05, 2014 7:14 pm

I fitted an OBC to my 90 325i at the weekend. I got it from Pacer and it is a 1986 OBC.

When I press 1000 and 1 to show the fuel remaining it shows 53l. I tried adjusting it using the screw behind the small bung on the left but it will only go between 52l and 54l.

Is there anything I can do to get it to show the correct 63l or do I need a later OBC?

Thanks
Ben

Ah, possibly. Although I think I used the one out of a 90 OBC.

I'll have to see if I can find the correct number. Any one know it?

Thanks

Polsta, I think you are right, thanks.

I will try the one out of my 88 325i. The 90 one I put in may be out of a 4 pot.

Thanks
