997.1 Tiptronic

Car went on limp mode. Researched and looks like the Mercedes transmission has issues with the conductor plate. We replaced that and it still didn’t fix it. Code says U0404 and P0715. Live on an island so options are not here. Any help will be greatly appreciated.

Thanks

P0715 is a code for voltage supply from the speed sensors.

Thanks would you know if the speed sensor was part of the solenoids in the valve body? We were able to replace the conductor plate but didn’t replace any solenoid.

No. The Tip uses multiple speed sensors to monitor the rotational speed of different components such and the input and out put shafts, which it reports to the transmission control unit.
