Hi after removing the rear bumper on my c220 09 reg today I found the rubber water drain pipe had fallen off and was lying on the blank panel that is fitted to the underneath where I imagine a offside exhaust goes on the c320-c63 etc. I watched a short video on YouTube before hand to get some pointers and the guy on the video said "remove the bumper slowly and unclip the hose" but it had fallen off a while ago and can't see where from. Any help would be much appreciated.
