Hi all I have a 1998 bmw e36 m3 convertible that i just bought about a month a month ago i have been loving it up until today... i had taken the car to the supermarket that was about 20 miles away when right after i used the cruise control the check engine light came on if anyone has had this problem and maybe knows whats wrong with it let me know i have always had older bmw's and they are easy to work on but this one is hard because i have no obd computer for the check engine light...
