The things you want to do . . . .
I would . . . . read and reset normal code about engine and climatisation
. . . . ok, most scanners can do: ie Palm Scanner
I have some problem about and do the adjustment of automatic transmission.
. . . . can not be done with a Palm Scanner or any OBDII scanner. These require a high end scanner such as the AST Retreiver or equivalent.
My tech just received the new 'module' (5724F) for his Retreiver. I got a chance to use it. WOW! This new version does LIVE data on ALL major modules in the car. You can look at the DI module including all firing voltages (primary and secondary). In the LH-SFI module, you can now easily read and RESET the S/A.
Alberto, any 'adjustments' to the tranny require a high end scanner.
I also do not like OBDII scanners for the same reasons stated by Steve. If you are going to 'stay' with Mercedes, then get a dedicated scanner.
