W204 2009 Drive Cycle For Engine Readiness, Steps Needed
Q. Can anyone advise on the proper steps to complete engine readiness for OBII? This is for W204 2009 C350.
There is no check engine light or any codes from the OBII scanner.
I can only find older models. I'm between a rock and a hard place.

My apologies- I don't have an answer to your question, but one of my own.
If there is no MIL and no trouble codes, what are you attempting to accomplish? No accusations, just curious.

Engine readiness sensors have to have a "ready" status for smog test. I'm simply trying to understand what drive cycle in order to activate them to pass smog test

IIRC, most OBDII systems follow the same "drive cycle" to set the system to ready ...

Cool, thanks. I had never heard of this without a car having the MIL lit, or other codes stored. With newer cars I've just driven them down to the smog shop, where they plug into the diagnostic port and in under five minutes, it's all done. No tailpipe sniffer or anything. Just more proof that the state is more concerned with 'tampering' than they are with actual emissions.

Still can't get it to ready. Spoke to the shop foreman. He said in some cases it could be a bad computer or even an O2 sensor slightly out of spec but not failing to throw it off. He had one car that took a 1,000 miles before it worked.
Going to see if I can get an exemption. This is crazy....

I've tried to drive cycle but there are various answers. I came across this.
1. Start engine cold and let idle 3-4 mins
2. Drive untilgauge reads at least 70c
3. Pull overand remain stopped with transmission in “D” for 5-10 mins
4. Proceed to drive vehicle (preferably on interstate)
5. Coast downfrom about 65mph to whatever is a safe speed (utilize off ramps for this)
Coast down 5-10 times😳
6. Once returned, let vehicle idle for 5-10 mins.
7. Proceed to the nearest bar & drink with a cold one.
I'm going to try the above.

I am curious.. What is it that is causing you ANY concerns or doubts that your 2009, (which, I assume this will most likely be its first smog test) has even the remotest potential of not passing?
Also, what are you using to determine "readiness" if, (as you demonstrate by the question you asked in your first post) you are unsure what it takes to get it "ready"?
Lastly, and this is somewhat rhetorical, why not go to a "Pas or Don't Pay" Smog Test Center? Which actually brings me back to this:
You may be able to get a60 day "extension" to submit to and pass a Smog test, but that requires full payment of all registration fees, in addition to the $50 permit fee that the DMV charges to issue a Temporary Operating Permit to display,, But an "exemption"? For a 2009, considering this is (presumably) its first smog test... I don't think it would qualify for an "exemption".
And for what its worth, a smog check also includes a visual inspection to ensure that all required components (like Catalytic Converters) are present...
Good luck!

O (Oxygen Sensor Monitor)
OH (Oxygen Sensor Heater Monitor)
C (Catalyst Monitor)
The smog test failed. Sine then, I've have over 500 miles.
I'm going to try the decelerate down to 20 mph which is a generic drive cycle.

A "pending" fault code is one that was detected but not enough times for it to trigger a CEL, and yet a pending fault code can delay or prevent readiness of one or more sensors.
Either way, you're going on about this all wrong.
A "not ready" state is the result of some element(s) of the emissions system not working properly. The way to address that is by trying to figure out the cause, addressing (repairing) it, and seeing whether the system in its entirety is able to reach a ready state.
What you are basically doing is you are looking at (the result) a "not ready" state, and you're expecting it to change without you even knowing what the cause is!
I suspect you'll be at this for quite some time.

Does your OBD-II code scanner have the capability to show "Pending Fault codes"? Or only "current" fault codes?

Scanner only shows codes stored but I'm not using it for that purpose; only to detect engine readiness.

The engine readiness was solved. Turns out it was a tune done by OE tuning. I went to the dealer and they updated the software and the back to OE tuning to
do the tune again.
Unfortunately, the manifold issue is back.
I also need engine mounts to be done. Considering the age of the car, maybe a used manifold? Not sure if that's too risky.. The new ones are about $500.
do the tune again.

0521 The charge movement flap (cylinder bank 1) has a Stored and Current malfunction.
