Not gonna be a cheap job.... the wheel is going to cost me around £350 (from a breaker... but airbag checked).. so that aint too bad.. but picture the scene.. im in my garage excitedly pulling at the front of my wheel to get the cover off and...... BANG!!!! the smell of gunpowder fill the air... and the smoke clears im left sitting in my boxster with a large deflated balloon hanging out my wheel!!! not gonna be nice

... what i really need to know is how long i need to disconnect the battery for and will it mess up the cars computer?? any ideas?
