What model turbo is that (not MB model but manufacturer model)?
That might help.
According to
http://www.turbo-product.com/Mercedes-Benz/
It is a Garrett TB2550. Other OM602s were equipped with Garrett TB2510 equipment as well.
This information was previously located by gsxr as well.

Garrett TB2510:

Both of which carry the same part number wastegate actuator:
432340-0004
I shot an email off to Garrett.

Hello,
I have a question regarding a wastegate actuator for the turbo installed on my 1991 Mercedes-Benz 300D 2.5 Turbo. The factory system from Mercedes uses a vacuum controlled wastegate actuator. I would like to eliminate this and return to the traditional pressure controlled actuator. However I am having difficulty find the actuator I need. I believe it is 433489-12. However that seems to be out of stock in most places so I was looking for an alternative. I was told that the TB2510 or TB2550 units might have a suitable pressure actuator that I can install on my current turbo, its part number is 432340-0004. I was hoping you could clear this up for me and perhaps provide me with some mechanical drawings of the actuators as well as put me in touch with someone I might purchase a unit from .
Thank You.
-Kris
