Oh yes... I know all about the orange foam of death, we have it under our Audi headlings as well... Terrible stuff!
I've removed the seats already, the car probably won't be moved now from breaking position just outside my workshop.
It a non sunroof car and the headling and indeed the entire interior is mint.
Thanks for the warning though, I've got to deal with it on my RS2, I'm taking the seats out of the car and covering the carpet before even thinking of touching the bloody headling.
