Does anyone know how a S4 (or any Quattro car) is tested for smog in CA? I think smog tests in CA uses dynos. Is there a special place to go for the all-wheel drive smog tests or is there an exception?

Thanks.

AWD cars are dyno exempt in ALL states by federal law.Sticker under hood by windshield says so!!!!

Dynos yet. Either way, AWD cars are excempt from Dynamic smog testing. Just the old tailpipe sniffer

I wish we had a dyno when I had my smog lisence back in '92. Hmmp

And they never put it on a dyno. They just hook up the sensor to your ehaust, a pick up to a spark wire and rev your engine up to within a rpm range.

We had new inspection standards go into effect 10/99. AWD cars are NOT exempt and they have to go on a special device to accomodate all 4 wheels to test the emissions at speed.
