I am looking to replace the multi-function switch panel on my sport steering wheel as it has a nasty deep scratch across it - I have a replacement panel but will need to remove the airbag to get it off.

I will have to disconnect the battery -ve terminal to do this, but am wondering if there will be any 'issues' once I reconnect? The car is stuffed with options including adaptive Xenon's, Nav, TV, BT, and the panoramic sunroof.

Now, the reason I ask this question is that I read in the handbook that the panoramic roof could need to be 'reset' by the dealer if the battery is removed/replaced - it seems that the full opening/closing won't work, only the tilt. Can someone confirm this?

Also, does it HAVE to go back to the dealer or is there some routine/process that can be carried out by me to reset it?

Thanks in advance,

Mark.
