2003 Z4 2.5 Computer

Asked by Apr 27, 2015 at 01:21 AM about the 2003 BMW Z4 2.5i

Question type: Maintenance & Repair

I am having problems with the computer n my Z4.

It beeps for 4+ minutes after the key is out..are there software/firmware updates for
it?  Every time I go to my mechanic, he charges me $90.00 to check it.

Where is the least expensive place to buy a quality computer if I need to?
