Sorry hit the wrong button, it was in the foitwell on my smart car so guessed it would have been there on this Merc also but nope, foiled again. Any other ideas??

I looked in the footwell, just realised you are saying behind the seat. I will have a look. Thanks

Behind the seat, remove the wire netting and it's behind there. Unclip the carpet and pul it up out of the way.
