Question about 2007 Mercedes-Benz ML 320
I rebild this unit & I still have this code & no up shift, all electric components are new exept the outer harnes
If you have replaced the speed sensor then i would think the problem lies in the wring as you seem to think also, you could try to fault find the problem or just change the wiring harness , both i would imagine are a laborious task , i would start removing the harness , paying close attention where each connector goes and as removing harness check for any damage etc you may find the problem wire/connector before you get harness completely out ,if no visable fault carry on with the new replacement. This code is triggered when NO signal is received by the ECU/PCM , so a close inspection of the speed sensor wiring and mounting would be the first step , good luck
