Any ideas there? I'm going to go die in a hole if you say "update daten"
someone did had problems with 2URAD as well but did manage to get it working. http://www.e90post.com/forums/showthread.php?t=709632
well, you better have some good tools to dig that big hole cos "update daten" might be necessary to solve your problem.
check the dates of the daten files you have. if they are dated before your car's built date, then you definitely need to update them since the required information may not be there.
