When removing the glovebox in my Octavia I disconnect the earth terminal on the battery to prevent air-bag errors from occurring. Might be of use to someone who does not have VCDS.

That's all very well, but then you won't be able to test the operation of the motor before reassembly. And getting it back in is so fiddly that you really want to make sure it's working before doing so.
