2002 Citroen xsara 2.0ltr VTS - Fluid leak - stevelew

I have a fluid leak under the dash on the passenger side in the footwell it is thicker than water clear and odourless no warning lights are showing or tanks dont seem low on fluid seems to be coming from something coming through the bulkhead from the engine compartment anyone got any clues as to what it could be and what harm could it be doing.

Cheers stevelew
