And now we're back to the original problem that was never fixed - the EGR Data Not Ready.
There was never any error codes neither the check engine light was ever on.
I searched this entire forum as well as the Internet. I asked dozens of mechanics who specializes in Mercedes engines. I can't believe no one can give me a valid advice.
Please help. What else could be wrong with my car?
you didn't get an error code or a check engine light because the components are working properly your problem is in the programming,the data link in the pcm has been turned off, take it to mercedes benz have them hook up their computer and turn it back on and everything will be fine.
