They rely on the star system or clones of it or more expensive bi directional scanners.
But the know how is the missing link. Most people don't want to share exact procedures so you have to experiment which could cause more harm than good.
The mechanical part is the same as any other car. There should be clear instructions by people that are familiar with it on how to use the Albrites with or without online. Also how to use star to finalize afterwards. The online can be bought per session it's anywhere between 35 to 70 dollars depends where you buy it.
The rest is easy. Hahaha
All good here my friend is relieved, if it wasn't for me he would have had to take it to a shop where they told him to rebuild the whole tranny. That's what you have to work with now-a-days.




WIS and Xentry is a tiny bit of the much bigger "cake" it seems....for certain task MB don't want outsiders to know.
Those in the know but is outside of MB, will make it their income to sell such services...but it is fair, they learn , they spend time...we got to pay for their time.
Usually those in the know are probably are ex MB staff or work or used to work for the OE of the mechatronics.
Good thing your friend have you to avoid needing the total rebuild.
However, I do see benefit of a total rebuild if wear and tear do occur on other mechanical components of the tranny.
Sometimes one will want to refresh everything if for long keeping, or some will only fix what problem occuring. Whatever suits them.
Some are duped into rebuilding too early.
Oh well!
