Since my car registration renewal required a smog check, I dropped by my local smog check station yesterday. The guy hooked the car up to the his computer, and after it spat out error code "P2004", he told me I would have to get that resolved first otherwise the smog test would automatically fail. The odd thing though is that there hasn't been any accompanying check engine light.

I did some searching on here and found a couple of handy (but scary) threads relating to P2004 --

List of Benz specific error codes

This guy who got P2004 with a pressure sensor issue

This guy who got P2004 with an intake manifold throttle lever issue

Looks like I really have no recourse at this time but to take it into my MB indy to find out exactly which P2004 issue I have (since there are multiple P2004 error codes)? Also seems strange that I haven't gotten an accompanying check engine light.

Just got the issue fixed. It was the intake manifold throttle lever issue, as feared and suspected. About $250+ for the (metal) part and $360+ for labor (primarily removing the engine harness and manifold and putting it all back again).

Not a big issue glad it was taken care of. :O when you're hit with a sudden 3k repair job it sucks.

Well I did also have to replace my front tires...get all the wheels realigned...and did you see my other thread on the rear pano sunroof panel getting smashed?

Ha, when it rains it pours....

Damn didn't know that. Ya I agree. My old slk was fine then 2 day wouldn't start at all, had to get a tow and there was all these problems and cost 5k to fix.

Edit: I fixed it and the next year I traded it in for 9k -.-'
