Mercedes-Benz Turbo Actuator

[CarTuning]

Does anyone know if I need to calibrate after replacing the turbo actuator or just install and drive? Thanks.

If it is not a third party product but an original one with the same number then it may not be necessary. Some models have the ability to detect boost position using Xentry.

What motor? Do you mean the electronic variable vane actuator or the actual wastegate vacuum diaphragm assembly?
Electronic variable vane actuators typically have a teach-in process via DAS/Xentry, and this makes sense.
A wastegate vacuum diaphragm does not have any teach-in procedures.

This is probably a VTG turbine with electronic drive. There are NO adaptations of this in DAS or Xentry. Just pay attention to the correct actuator number (for OM642 G277) when ordering on AliExpress and the ease of movement of the turbine blade drive. Install and use. We have installed it several times and it works great.

I also replaced the VTG actuator from HELLA to a Chinese model.
I bought it from a turbo specialist who programmed the actuator using the original codes.
It seems important that the maximum and minimum angles are identical.
That's right, programming from Xentry is not possible.
Hope this helps.
