Limp Mode 3006-1 and 2027-4
Hello,
I am getting a code on my 2008 e320 bluetec
I have had the mass airflow sensor for a while. But the down stream DPF sensor is a new one. Could that be just the sensor itself bad? Code 3006-1

A CHANCE TO FOCUS
you know it's your own lottery you are playing: now you got a limp mode!
Dont let the engine blowup. Now is your call for action...
current is hot - Stored faults are secondary
Act upon the current code poiting to MAP issues.
May not be the sensor itself... W211 have intake plenum issues.

focus on the obvious first...
look at live MAP data stream at idle. Is it in range or in the weeds?
Somebody may have left the plenum air intake disconnected, so now MAP can not work.
Somebody may use cheapo K&N air filter so MAP sensor is jacked up dirty.
Any other modules faulted?

Now that you have these ECU faults recorded preciously,
Go ahead and clear codes to get a fresh start then rescan to see what else comes back...
we expect MAF only.
It's weird to limp mode from MAF condition only....
You gonna need to read your live data to see what is off.
