Irieite… weather is sounds right or not this is just the way it is done. I’ve been fixing MBZ for almost 25 years and go to update classes yearly. I learn something new every time and this was one of the things I learned at one of them. In fact this must be done when you replace the crank sensor, motor mounts, flywheel, ME controller and in some cases to cure misfires.

Iacombe… disconnecting the battery cables will not re-set the Sensor Gear Adaptation. It must be done with a scanner then a certain drive cycle must be done to perform adaptation. Drive the car in 3rd gear at 2,100RPM with 50% load on the motor. Now you can see why you need a scanner to do this. The only way to tell if you have 50% load is with the scanner.
