Hello all, I am having a bit of a problem figuring out my ventilation timer. 5 months ago moved up from my 83 320i to a 89 535IA and learning something new every day. the last hurdle on the OBC is to get the vent timer to work.
The manual tells me to depress the timer button and then enter the numbers.
Well that doesnt work so perhaps someone with a bit of experience on this could fire me off a hint.
I would be very appreciated
