Recently disconnected the battery to rid some fault codes following icv problems. Went through the handbook procedure to reprogramme the sunroof and it just won't play ball!? When I press & hold it for 5 secs in closed position - it opens, closes, tilts etc... If I press & hold in the open position it tilts, closes, opens etc... Managed to close it for now by pressing the button in open postion until it returns from tilt, then quickly let go just before it starts to fully open. It doesn't make a good seal because I have to guess when to let go of the button (when it looks about right).  I've had to leave the dial turned to OPEN for it to stay closed!? Now causing a big condensation problem because of the cold whether. Any tips on reprogramming, other than the full procedure stated in the user manual?

remove the ecu from the sun roof motor open the unit up and you should see a round magnet, make sure it is not broken, get a speaker 3-4 inch magnet on it and leave on it for a day, there is a red colour'd chip were the magnet is covering clean with a cotton bud, also look for water makers on the board if ok put back together and try it then should work ok if not the chip near to the power lead has gone and the unit should be replaced.

Sounds promising, how do I access the sunroof motor and its ecu? thanks...

thanks for the url, followed all the instructions & thoroughly cleaned magnetic disc, refitted but still wouldn't reprogramme. courtesy lamp wouldn't prise out, without brut force because the plastic rim sits about 1cm proud of the metal clips  :question (immpossible to depress the metal clips with a flat head screwdriver or similar) however that's not anyones fault except GM. couldn't figure out pic 4 (shows the magnetic disc sitting over the spindle hole  :exclamation) so re-positioned the disc as shown in pic 5. I am very grateful and definately couldn't have done it without this step by step link. Maybe need to replace the whole unit. thanks for the info, Steve
