[B]There seem to be several folks who report errors when trying to connect the OBDII scanners to MB cars. In addition, my local Auto Zone says they can't scan my car because it's a Mercedes (I know this isn't true).

They might not have a scanner that reads European cars, different protocol than US vehicles

Can someone tell us why the OBDII scanners are having trouble interfacing with the MBs?

Some scanners are make specific, as stated above, our I/M emissions testing program went to OBD scanning in Jan 03 and we have a 98% connect rate for 300E's with multi-protocol OBD software, I'm not at work or I could find out what protocol MB uses.
