Engine diagnostic codes $7EB, $7E8 and $7E9

My check engine light recently came on and I got the following codes from my diagnostic tool. $7EB, $7E8 and $7E9. Can someone tell me what these codes are for?

Did you find out what they meant and how you got rid of them?

Designations $7E8 and $7E9 are not what one would traditionally refer to as fault codes.
These alphanumeric designations are actually nothing more than menu tabs for accessing data stored on various vehicle-mounted modules.
Can These Codes Be Fixed?
Because of the fact that menu designations such as $7E9, $7E8, and $7EA are not actual fault codes, but rather data subsets, they cannot be cleared.

How does one delete the illuminated check engine symbol if these designations are not actual error codes.
They also appear to be recorded as as an actual error code?

Right, I have the same issue. Codes $7EB, $7E8 and $7E9 and CEL on. If they are not actual error codes. Does it mean I need to use a mercedes specific scanner to scan all modules (instead of just OBD scanner) to find the codes?
offcrusin, did you find out the problem and or a solution?

Yes need a scanner with MB specific capability.
