I'm desperate! Not like I haven't had enough problems with my C230k in the last 7 years, but NOW I have a huge problem. My check engine light is on and I need to get emissions. Of course my wonderful car just went off warranty, so I decided to not get raped (sorry but its true) by Shumacher and take it to a German Motor Specialist (Bad idea). After diagnosing my car with a "un-diagnosable problem", they told me the check engine light had gone off and to take it to get emissions.

Well, I did, and I got rejected because "the OBD2 System is Not Ready". Which means absolutely nothing to me. So now, I don't know how to make the system "ready" or even what to do. Plus, I have no idea what the underlying problem is because no one will tell me.

So...If anyone can help me or has any ideas about what I should do...Please let me know! Thank you so so much!

This post is useless without codes.

Please post the codes. The will look like P0700 ... a P followed by four digits.

They reset the codes but the system is not coming ready for some reason. Until the problem is fixed the system will probably never come ready.

Don't ignore the CEL. It's not just something to fix when you need to do emissions ... often it will cause bigger problems if you leave it.

Did I mention I know nothing about cars/my car? So what you just said makes no sense to me. At least I tried I guess...

So, the check engine light is no longer illuminated? If that's the case then there is still some systems in a pending state. You will not pass, or fail emmisions test until the systems go through their check... I read a little about this in my OBD scanners manual. I guess some systems just take time to become active, but I could be wrong... Again, is the CEL still lit?

Zeet was asking for a list of the codes or the code that caused the CEL to illuminate. You can get these codes for free by taking your vehicle to Autozone, and having it scanned. They will only scan it if the CEL is on.

Arrrgh! Another newbie with a question, and no info.

I'm desperate! My dick gets swollen when I'm around hot chicks, and I don't know what to do with it! ;)

But, just for shits and giggles, check your fuses, and see if the OBD fuse is blown.

If they can at least tell you what OBD2 readiness monitor is not set, you can then tell us and we can suggest what you have to do to make the car ready for emissions. This might help a bit: WikiAnswers - How do you set obd2 readiness monitors

Normally that happens as a part of driving, but if you do a similar process and the Check Engine light comes on, or if it has come on since you posted, we need the codes that will come from an OBD2 scanner. Autozone and other parts stores can rent you one or scan them for you.

Ok amandastar1, here is what happened....

Since the outfit you took the car could not diagnose the problem, they just cleared the DTC (trouble codes) from the car. Dont take you car back to them...ever... Now, the thing is when you clear the trouble codes, it resets the ODB2 readiness cycle also.

ALL THIS MEANS IS that you need to complete a couple of drive cycles before the ODB2 monitor will indicate that all ODB2 functions are ready and functioning properly. TO DO THIS, just drive the car normally for a week or so. That will usually complete the required ODB2 drive cycles.

You can take the car to an Autozone and have them hook up a code reader that will tell you if the readiness cycle has been completed (before you take your car back to emmissions inspection).


This does not address the original issue of what set the trouble codes to begin with, so they may come back. If they do, visit Autozone and get the codes and post them here. We will try to help.
