2001 S500 question on self adaptation

[engatwork]

I'm working on the above listed car and am getting the following:

Self adaptation in lower partial load range, R bank/L bank.
Self adaptation in upper partial load range, R bank/L bank.

The actual values were all over 1.3. In addition, I'm getting a reading of 150dF on the intake air temperature sensor. Based on what I've been reading the temp sensor is integral to the AMM. The car has a little over 104k miles on it and is still on the original AMM.

I'm suspecting the AMM needs to be replaced. Any thoughts/comments are appreciated.

Oh yea, I'm seeing a slightly rough idle along with poor fuel economy. Check engine light comes on after a while. Plans are to test the AMM tomorrow.
