here it is... 87 325i 9 button OBC. Havent driven my car in a while so when i went to start it this morning... no luck. Gave it a boost, but i noticed when i got in the car, that the OBC was messed. Nothing works anymore except the time, date and timer. Everything else shows PPPP. PPP.Pkm/h, PPP/100km, etc, etc. Anyone ever have this problem or know of a way I can fix it. thanks.
