It seems that MB can't get the AAM issue resolved. Just got our 01 ML320 out of the shop after experiencing intermitant remote door locking & alarm issues. Using the remote, one key might or might not operate the locks while our second key would work fine. The icing on the cake was the fact that the alarm would start going off for no reason--even IN our garage.

Our service writer told me that MB no longer uses an "AAM". Don't know if these functions have been decentralized or if they are simply calling the module by another name. This is our second M-Class and both have had numerous AAM replacements. I just cannot figure out why MB can't get their act together on this issue.

My question is this: Does the AAM have anything to do with the function of the fuel guage? Since getting our caqr back, the fuel guarge has been acting MORE squirrely than normal. Our last fill-up was 50-75 miles sooner than what has been normal. My wife reported that the guage seem to drop like a rock.

Thanks for any input/suggestions
