Hello All, As some are already aware here, my car has gone down since July. The TCU has burnt at 500km of my home during holidays ! I bought a new valve body/TCM (VGS2) in order to replace the old one (VGS1) As you can see, valve body are pretty similar and I saw only one difference : No difference on upper side. I made some cleaning and changed one valve : I also changed one solenoid. Unfortanetly, when I refited the whole my benz refused to move. I used DAS and no error code. So i remove one time again the valve body and check again but I found nothing. I will retry tomorrow with other solenoids... Do you have any idea ?
