Thanks for choosing Just Answer . I'm Wolfgang here to help!!

I am confident we can resolve your problem together. Please
understand that I don't know your skill level. In most cases when you have a problem
with the way the vehicle performs, specialized tooling is required to acquire computer
data/information or engine testing results. We didn’t build these complicated vehicles; we
just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results. Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!! I am also going to direct you with the fastest, easiest and most common things to check first. Please be
patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in
return. I will also continue assisting you after you have rated me, if necessary. If there
is any reason I cannot get a positive rating, please let me know why “in advance”, so I
can go another direction for you. I am sorry you’re having this problem; I’ll help you
through it.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

I do need a vin # to get the factory information to assist!!

looks like a trans code issue. was a total vehicle scan of all modules performed ?

Customer: replied 1 month ago.
cleared codes and roadiest .all P codes
Expert:  Wolfgang replied 1 month ago.

on benz there are other modules like the abs , trans , ignition switch and others. these modules communicate to each other so this total scan is very important to see all modules to isolate if it is trans, abs, engine or another area.

Snap on scanner is a very good scanner but i have seen times the translation from generic code to manufacturer specific code can be skewed and may lead you in the wrong way!!!

MB scan tool is the choice to get the correct info .

i just want the correct info to lead you the correct way in an efficent and logical way!!
