Have you tried just clearing them and seeing if they come back?

I did , they alomst come back immediately. I am clueless. Did the plug on the Thermosatat come off and is causing this, Is there some plug thing in the door module that might have come undone?

No change in the ride quality or the MPGs drives super smooth, no hesitation or rough idle...

this is so confusing...

Javvy, to rule-out the battery, fully recharge the battery and have it load-tested [at AutoZone/PepBoys/AdvanceAuto/ etc.]

Look around the parts that were replaced and see if there is any connector/wire that hasn't been plugged in. Check if the O2 sensors are plugged in properly. Did you check the electrical connector on the thermostat?

Checked all hoses and connectors, all look fine to me. Please any one give me some direction of what should be my next steps in diagnosing this problem.

I feel your frustration...
Other than battery voltage, I am not sure what is common among all those errors. I wouldn't start replacing parts...

So, here is what I would do - take the car to MB dealer, have them diagnose. They probably will charge an hour diagnostic fee. Their star diagnostics may reveal the culprit. Get the printout from them and decide if you want them to replace the relevant part or not.

thanks you PCY...that was what I was thinking too.....Let me do a final check one more time; take the air box out and check for any hoses that might have come undone when I was doing the thermostat......if I find nothing then I will have to take it to the dealer for diagnosis only...lol
