Hey guys. Does anyone have Isofix bars in their C5 A6? Is there any chance you could pop the seat up and get me the part number? There seem to be several versions of the bar - the one I need has a width of 18cm between two bolts. I have obtained a copy of ETKA and contacted several dealers - ordered what I thought was the right part, and got the wrong one Don't to keep buying parts I can't use and can't return. Thanks!
