Good day together, I hope for your support, because I have a problem with my Mercedes G-Class 400 CDI, built in 2006, 5-speed automatic. The vehicle starts normal and runs at full power. But after about 15 minutes the acceleration remains, although the gear D is inserted. The engine turns up, but the vehicle no longer moves. After you turn it off, and you let it cool down passes the same problem again. The following has already been tested and out chlossen: Gear sensor has already been replaced Gear oil level is in order Automatic gear control unit has been tested and works perfectly Does anyone have an idea what this might be about? I am grateful for any hint! Best regards
