I have a 99 B5 with dealer floor mats that have the integrated buttons for attaching to the carpet. The problem is the mating buttons on the carpet are only available on the front. I have kids and the floor mats constantly get shoved up under the seat. It pisses me off to no end that they didn't put those in the rear where it seems like they are needed most. Can the carpet be lifted and these buttons installed? Any other ideas for a solution? Thanks.
