Whilst working on a 3 Series Touring today, we noticed the rather nice smell of bubble gum which was emanating from a liquid dispenser clipped into a centre air vent. 

Just a quick word of warning; around two years ago one of our customers had a similar device fitted and it leaked.  The car (Subaru Impreza WRX) needed a new dash + ancillary controls etc as they were badly marked by the dripping liquid.

It may be a one-in-a-million fault but we thought we would share it with you anyway.
