Auto electrician or impossible?

[jbonnett]

Anyone know if it's possible to get the standard alarm system on the E46 convertible to close the roof and windows with one 'beep'?

My old E36 Evo convertible used to do it. Park up, roof and windows down - beep - windows and roof shut.

Surely total closure can be done on the new and improved E46 without the need for an aftermarket alarm?

I know you can hold the key in the door and it does it - surely some electrical trickery could do it from the key fob?

One place said they could do it but you have to hold the button in on the key until the roof and windows were closed anyway - so you might as well stand there with your key in the door - seemed a bit pointless to me. Something to do with pulse lengths??!

Any ideas?
