So I drive the S daily. I went to work, 6 hours later, take my lunch. Get in the S and when I start the car it smells like clorox, windex... etc. very strong, instant headache. I had to keep the windows down. Car drives like normal. After work same smell came back... I'm not low on any fluids, the engine bay smells/seems fine... So hopefully someone can tell me what to possiblely to look for.

 

It might be mildew aroma from the vents.
