Looks like I may have a small problem with my S4 already........
Had the air con on all day today and its been smelling a little niffy when I switch to the Econ mode. and this evening I seem to have water dripping from the passenger side, underneath the glovebox.
Its still heating and cooling ok so I dont think it can be the heater matrix, is it possible that I have a loose hose somewhere behind the glovebox?
Will take a look in the morning, but need to know how easy the glovebox comes out?
Other than that, the car is awesome. Mid range grunt is soooo much smoother then the re-mapped S3 I had
