When I bought my car a ouple of months ago there was a tear in the the steering wheel cover (pic below)
Found a part number from a thread which was 90437334, went into VX to order it and collected it today. only to find the cover is greyish whilst mine is black and the new cover doesn't say "airbag" on it for some strange reason. Looks like it might be a scrappy job to find one as that lil tear is kinda annoying me now, shoudl be fun as a fair few scrapped ones already have had the airbag deployed.
Guess I might be putting the thing up in the FS forum, not even sure if it can accomodate an airbag, feels a bit too hard and as it was a special order item I can't return it D'oh!
