My water pump may be failing also but last time i checked the engine compartment (by the panel behind the seats) i didnt see any leaks in the water pump.

But again, even if the water pump is failing, how would the smell get inside the cabin ?

Porsche dealer should have a warranty in this repair they did, right ?

Thanks

heater core's seem to fail when the water pump does for some reason I don't yet understand. so if your water pump is now going bad, it could mean your heater core is as well. its easy to open up the area and see if there is antifreeze in the heater core box.

Hmm i doubt that the core heater fails too. Most probably its malfunctioning (rather than failing), until i fix the water pump ?
So, maybe when the WP is failing, the Core heater is not working as it should.
