Been browsing classifieds, ebay etc for a MFSW but want one that is compatible with my airbag to save some money, think I have found one but was wondering how to check if the part is correct? I have the number for the MFSW but not the one I currently have it's a 55 plate A3 S Line if that's any help and my steering wheel looks like this (sorry about crap picture):

The part number for the one I found is: 4FO 419 091 BT URS and from the pictures looks identical to mine

Any help would be appreciated
