My 02 c320 is throwing p0705. I thought it was the conductor plate because of the symptoms seemed the same. Changed it and still have the p0705. I can erase it and it will show again just by going through the gears. I think it is pointing to a modul at the base of the shift lever? What is the part #? to order? I've had to replace the servo motors, so I know how to get in there, but I was hoping for some guidance before I dig in. It would also be nice to have the new part on hand.

Is is possible that all I need to do is hook up the laptop code reader and erase the codes??

P0 705 is a code for a defective shifter.

Has any liquid been spilled in the area?

The complete shifter must be replaced.

Thanks Doc,

I took it all apart, New ones are pretty well protected and covered. Seemed in great condition. Aligned the switch and assembly. the code is 2067 ME error, stored in egs control unit (p0705). it shows p# 112-153-08-79. When I try to digital test the EGS w/MB Soft 7.3 a few times it wasn't found or didn't respond, then I got a p240c for p# 030-545-23-32. the carsft doesn't explain what's up. Maybe you can give me some insight. Is it possible the shifter switches are ok but the units the signals go to are broke?

Thanks Doc, Right you are. I got a used shifter and have 50 miles on it w/no new P0705 and the tranny is working nicely. It should with a new conductor plate and fresh ATF.
