Exhaust port under front passenger side ?

Exhaust port under front passenger side ? E39 530d 2001 model

today I noticed the rubber panel under the front passenger side of the car was sagging badly and filled with diesel fuel, the diesel has eaten the rubber panel so that it sags like a cieling panel after a geyser burst.

So I removed the panel completely, washed it with "handy andy" and the proceeded to look for the fuel(diesel) leak, non evident, tried running the car, engine off but ignition and fuel pump on to create pressure etc...not a weap, not a drop...nada....to play safe I tightend all the fuel pipe clamps by an extra 1/2 turn...just in case.

then I noticed in the same area an Exhaust port that comes from within the engine bay and is ported overboard in this area as well, the rubber panel actually has an oval cut out in it to allow for this exhaust port to protrude, what is "vented" overboard thru this exhaust port/vent...could it be diesel..?

anybody ?

I drive a X5 diesel as well as a E39 530d and know that the X5 has a small exhaust that exits under the passenger side of the car. That is for the heater that heats up the diesel before it enters the manifold. On very cold mornings (of which we here in the Cape do not have to many of) you will notice the exhaust vapours exiting under the passenger door - which is the heater for the diesel fuel) but i personally have never noticed it. Can't remember seeing it on my E39 but then this was either optional or only available on cars for cold countries/areas in SA. As far as i know there should not be any diesel as such be coming out of that exhaust!!

as far as i know that heater is for heat inside the cabin (auxilary heater), it runs on diesel.. might have a leak in its feed somewhere? or else it just does not burn all the diesel ?

some info here..
