I got the software on Friday, along with the enhanced Mercedes option. I've gotten to the point where I read all the codes that the dealer can, but a regular code reader cannot. Very nice to have this information at my fingertips now, any time i want it.
Looks like I have some work to do to figure out troubleshooting for each of these.
The fuel trims are pending, no engine light yet. This has been a problem child for a while now.
C1140 - not sure, perhaps the steering angle wasnt reset when the battery was last hooked back up.
C1529, C1332- no clue yet
B1858 - not sure, perhaps another screw up from the shop that recently installed a new AAM for me
B1470 - confirms the empty reading whenever I fill up, my guess is the resistor wiper needs cleaned, if not, then the fuel pump/sender needs replaced.
