Hi. I'm very new to the forum and Internet in general. Apologies for my ignorance and mistakes. My 2003 S211 is suffering and so I am. I have just not been able to work this out. I have a code that keeps coming up. (P0720) Gearbox is going into limp mode and on occasions will not engage reverse from drive when in limp mode (will from park?). Do I just need to change the connector and then reset the codes or does this reoccurring code related to the conductor plate itself. It will get stuck in gear. Usually 2nd I think. Can reset by turning off, waiting a little while and then start again or by using a very basic code reader to reset. I have access to star but not familiar with it. Friend has a version of it but nothing definitive coming up code wise. I have a few separate issues with the abs sensor(s) on the rear. Changed one but fault was still there. However I do not believe it is causing the gearbox issue. Do I change just the plug with filter, gasket etc or do that plate? Any help greatly appreciated.
