Hi all, new to the group,I'm looking for some help. I've not long bought my 08 A6 s-line 140bhp and I've just noticed a button on side of the drivers side footwell with TM printed on and what looks like a led light on. I've pressed it with the engine off and nothing happened but I'm a bit wary of pressing it when the cars running just incase. Hopefully these 2 pics upload ok. Thanks for any help.
