For anyone else who has this problem, P0705 is a fault code for the Transmission Range Sensor. This is located in the gearshifter module. Make sure you pull your GSM and get the EXACT part#. I went to eBay and entered it and got six. I bought one for $98 from a 05' C230 and it did the trick. Went in and cleared all my transmission codes and everything is fine. If you need help email me and get contact info and I will guide you.

I thought he just changed the transmission range sensor?
Wait, I thought OP, guyszoo said that it was the transmission range sensor, and the post # 10 implies that he just changed that? Or do I need a transmission range sensor PLUS and ESM? I don't even know what an ESM is. You have the link for that? I am not mechanical at all, I probably just need to buy the parts and let my mechanic put it together. I was in the same position as OP, had some rain, then all of a sudden the sporadic limp modes. Now it's more permanent in limp mode. I got the same engine code by the way.
You need a 'new' ESM which is the whole shifter, though it's typically only the electronics that
are bad, they don't sell just the sensor. New is like $700, so definitely go for a used one.
Get the pn from your local mercedes dealer, call and ask for a quote on the shifter (which from the dealer will be like insane) and then ask for the pn based on your VIN.
Since you can't align it I would recommend replacing the whole shifter. Don't attempt to swap the sensors.
I have a thread here somewhere with instructions from when I went through this.
Don't wait till it fails completely. You will be stuck where ever it decides to die with 2nd gear only.
Here's some sample part numbers (not necessarily correct for your vehicle!! There are different ones,
as I found out, with different connectors)
2032678824
2032672124 , 2032672724 , and 2032674924
