windshield fogs and defroster makes it worse, bad scent from vents
When my windshield fogs up I use my defroster and it gets worse, bad scent coming from defroster, but it doesnt smell like coolant, and it gets a rainbow colored haze. This happens mostly when driving. When sitting and idling it clears up VERY VERY slowly. When I start driving again, it immediately fogs up again to the point I can't see. The air is hot that comes out of the defrosters and my vents. What things could be causing this so that I can check. The car is a S4 NA with a mild street port. No other mods on the car. Please help!

if you get a "film " on the windshield,and it feels a little greasy,most likely it's the heater core..sounds like a heater core leak..had one in my "other car",and it would leave crap on the windshield..that's my take on it..have you checked coolant?.pressure test the cooling system..look for signs of leaking especially around the heater core and inside the car(floor)..another thing..if your car was stored or was outside for awhile and dormant..you just may have "critter litter" in your vents..you know animals!..anyways that's all I can give you ..

Also check for oil leaking on the manifold. When my OMP was still in and leaking it would drip back there and stink up my car and coat the windows with rainbow haze after a while like you described.
As for general fog, My GXL used to fog up something terrible in the cold/wet winter, heres what worked for me.
1. Thoroughly clean inside of windows with glass cleaner.
2. Use clean towell to dry off completely.
3. Apply rain-x anti fog or whatever you got, let that dry.
4. Run defrost at full hotest setting and make sure you have recirculation pressed.
(^^ This makes it worse for a while but the idea is to evaporate the extra moisture in the car.)
5. Keep windows shut whenever possible to avoid dampening interior further.
Ive found even a little rain in the car causes lots of fog for a bit

in all fairness though - this is an effective method of determination.
Im not telling him to crack a 4liter jug of antifrezze and start chugging.
touching you finger with glycol rsidue to your tounge is certainly not the MOST health consicous thing to do but it is certainly not going to cause blindness or sickness in any way, otherwise I wouldn't be typing right now.
besides, I don't see any other really really effective suggestions posted thus far and its not like he HAS to take my advice anyways...if everyone on here took everyones advice we would have a nation full of people who are afriad to change their oil from mineral to synthetic..........wait maybe thats a bad example - LOL
edit: but Im sorry if this was enterprueted as a harmful suggestion and will use better discretion in the future - I just think its a quick and easy way to check and see if there is a hole in the heater core - sorry

Some people are jumping into conclusions here...
I've only seen one bad heater core so far.
I've seen TONS of bad heater hose connections to the heater core at the firewall.
The coolant tends to seep back into the interior.
That stuff slowly turns to vapor and rises...guess where is right above?
The windshield.
