mark26061984 0 Posted February 6, 2008 Hey guys. bought what i thought was a spoiler control unit off ebay (part number 535 919 845 A) went to fit it to my 89 1.8 16v and its different. :? The part number on mine is 535 919 845 B. Could anyone tell what the difference is other than the plugs being different and if this actually is a spoiler control unit.
