Thought it was worthwhile to mention I just had to do my CA smog check for this year's registration this weekend. I had FSI build me a 4.0L last November and I've put 6k miles on it since. The car passed with flying colors. Anyone in CA concerned that a larger engine from FSI may give them issues come smog check time, need not be worried.

Nice! Thanks for the report out. I'm on this path now with the 3.8L. If your 4.0L makes it, the stage1 is a cake walk. The process seems easier than it used to be. I think it is now simply an interrogation of the DME. I can't remember when any of my cars were put on the dyno with a tail pipe sniffer.

Yep, that's right. In CA, cars built after 2000 don't get the tailpipe sniffer. It's just a visual and DME inspection.

Does your engine have the UAOS or the OEM set-up ?

FSI used a new OE AOS

Mine has the UAOS. It is visually different, but doesn't have the boy racer look. I would expect it will not be noticed. I'll let you know in 1.5 years...

Your engine was probably done before the UAOS had proven itself.

FSI has installed 15 UAOS's this year on their engines..

UAOS will pass Emission "sniff test", and according to CARB Apendix G , the visual will not be a problem either as it need no "exemption code number" on the part.

My '99 C4 gets the sniffer, (no dyno, since its AWD). Anyone know if an FSI motor will pass a sniff test?

After taking FSI's 1st engine rebuild class, I rebuilt my original 2000 Boxster engine with 60K miles to 3.6 liters. Once finished I passed smog test with emisions about half of the prior tests.

I have a 3.8 FSI and the only thing I have to do is change the x-pipe back to stock exhaust once every two years. It passes the sniff, but fails the visual.
