Elektrik: E38 740d 2001 ACC problem

[mavic]

Hi. This is my first post here. Sorry for writing in english
I have a question about Active Cruise Control. When I press on/off button on wheel "inactive" is displayed and system wont work. I know it needs calibration. Anyone know how to make the calibration ?

Regards from Poland.

Hello
in this tread page2  http://www.7-forum.com/forum/4/acc-a...o-91261-2.html you can read that for calibration special equipment is necessary.
So only BMW can do this.

Hi and welcome to the forum!
Do you have a local BMW dealership in Gdansk? Normally they should be able to adjust the ACC.
Don't know about the prices in Poland, but I paid just 66,- EUR here in Munich for the adjustment.
Otherwise you could contact our member @ lexmaul, who did some adjustment by himself with the help of a diagnostics software.

Best regards,
Markus

Thanks for Your replies. I have exact system as on the video. When I contacted BMW Dealer the told me that they never did that before so they have to learn and it will cost nearly 200eur.
Radar must have the error cause I changed air condition fan last week and it is on the same mounting screws.
