P0410 Secondary Air Injection System Malfunction

[RussBarnes]

So, Evil, if they don't use them in Europe why do we have them? What does the lack of one do I wonder? Or are there other plumbing changes? Does blocking the port and eliminating it do anything that would improve things (of course it would violate some law) but curious minds would like to know why the same engine has it one place and not another and what are the differences in engine running characteristics. Somehow I have to believe not having it makes a better engine than having it, if nothing esle for the differences in this thread about when it fails.

Worked it out eventually, only USA smarts have this part.

We have some of the most stringent Emmissions Laws in the world. The same reasons the diesel smart and other diesel powered cars are not allowed in the USA.

Stringent emission standards yes; not so bad Mercedes and VW won't have diesels here for 2009.

I do believe the MB ans VW diesels are both MB. I think they use urea injection in the Bluetech engines. Just as a side the new VW Jetta gets worse fuel econmy than the smart plus you have to have the dealer refill the urea tank.

i'm hitting 6 months and just crossed 4100 trouble-free miles (knock plastic!) with my smart, i get worrieder and worrieder everyday "shifter and valve and switch, oh my!" (wizard of Oz)

when i hit 5000 miles, i'll get the shifter lubed when i get the oil changed. talked to the dealer yesterday, they've had about 6 shifter failures so far, maybe call about that valve, kill 2 birds with one stone.

You have a different routing of the exhaust which is why the USA exhaust won't fit any other smarts. Yours comes out the manifold that usually joines to our exhaust header, yours goes up into some strange mixing chamber with this dodgy valve on it, then out the top of that into the exhaust header.

That's the biggest joke i've ever heard, how are the 6.3 Hemi powered vehicles getting through these tests? Sounds very much like they have stringent tests for imported vehicles and not home grown ones.

just thank uncle sam

The Secondary Air Valve (whatever That May Be (descriptions Anyone)) Is One Of The Most Common Things That Goes Wrong On The Smarts. I Am Almost Sure That Smart Will Address This Issue In Some Sort Of Recall Because It Does Seem To Be One Of The Few "flaws" With The Vehicle. I Wonder If Dealers Can Replace The Valve For A Minimal Fee Before We Take Delivery!!!???

Aw, Kane, you and your European friends get all the real interesting cars we can't have. The EPA and NHTSA are so full of crap it flows like the sewage it is. Downhill..... onto us.

I was only stating what the current experienc on this part failure was relative to smart Center Round Rock Texas

Yours, at 270 miles, seems early compared to what most of us are experiencing

1. All smart cars imported must comply with the stricter California Air Research Board (CARB) limits on emissions...this way they can be sold in all 50 states including the 13 states that have adopted the CARB standards.

2. Re the 6.3L hemi.... if sold in the 13 CARB states, it must comply exactly as the smart does.. to do this, the CARB Hemi has giant honking 3 way catalytic converter, EGR valve, special evap, and recirc system, as well as leaner mapping in the ecu...all at the cost of reduced power...

Bottom line is none of the imports are held to any higher standard....but we do have several confusing and conflicting standards.... My state of Texas has three different standards depending on which region we live in... but then... you could put several EU nations inside our state and have enough room leftover to add in all the British Isles.....grin

3. My 6.8L 3 valve(technically a hemi) V10 is rated as a LEV (low emissions vehicle). During emissions testing one can describe some of the various emission products as cleaner then the intake air...curious... but true, in some of our more polluted cities

4. I believe the smart got a ultra low emissions vehicle (ULEV) rating here in the USA where we are more concerned with Sulfer and Nitrous Oxides then CO2...Europe is thoroughly invested in the global warming hoax and their standards are weighted more against CO2 emissions.... notice the bias towards diesel car motors.. bigger tax break and they do not seem to car too much about soot or sulfer byproducts like we do.
