How to reset the TCU (trans control unit)
Does anyone know how to reset the TCU in a 2016 GLE400?
I already have done it for a 2013 GLK350 by the following steps acquired from this forum;
Steps to Reset the TCU. Resetting the TCU will reset transmission to factory shift points and the car will 'relearn' your driving style.
(1.) Turn the ignition key to the on (not start) position.
(2.) Press the gas pedal to the floor and hold for five seconds.
(3.) Turn the key to the "off" position (don't remove the key), then release the gas pedal.
(4.) Wait at least two minutes for TCU to reset.
Thank you
