Hello to all, i'm new to this forum, just picked up a 04 545i with a 6 speed manual.
Fun car!! but first problem was vibrating door speakers, so i took the panel off and to cut a long story short i unplugged the airbag and turned the key on for some reason.
No need for lectures i work on cars all the time and know i did the wrong thing.
The problem is the scanner im using at the moment Launch CRP129 says no srs dtc's... it worked fine on a mini cooper resetting AB light, brought up other dtc's on the e60 but no airbag !!??
Anyone had this? is it crap scanner? I called launch, they said it should work but who knows..
Any input would be appreciated thx.
