Since I have to complain about cold water loss and this has come to light again under my floor mats, I guess it has crumbled my heat exchanger.

Now I started to disassemble the interior.
When I made the 90 degree arcs of the ventilation inside, I noticed that it is dust dry in the pipe itself and that there is no sign of cooling water.

Shouldn't the broth be standing there ??
The broth is still standing in the passenger/driver's footroom.
Just wants to be sure, not that I'm ripping out the box completely and then it was a set with X ???

Does anyone have another idea?
