New owner, questions about services performed at dealer
I was able to look at its service history thru carfax and get an idea of what's been done before purchase. This brings me to what I'm writing about today. Our local MB dealership serviced the car at about 77K miles, but they did not list any of the items they serviced. Instead they listed the following:
- Recommended maintenance performed
- Maintenance inspection completed
Now as I understand it, the transmission should be serviced at 70k. So, I am curious if they did the transmission, and maybe even the diffs. Unfortunately, they have no interest in disclosing what they did. As such, I am curious what the likelihood is that they would have taken care of that based on their notes?
I will be climbing under the car when it warms up a little and maybe there will be some clues down there as well. Would really love not to do a transmission service if it has just been done.
Thanks for any help,

The dealership (any Mercedes dealership) should be able to tell you if any tranny service has ever been done.

I'll add I go through the Maintenance Manual that was included with the Operators Manual and make sure everything is done. Should be in the glove box.

When they don't find the associated price, perhaps it'll be free.
Plan B: buy some services like oil change wipers and then ask for something free.

The "Mercedes Upgrade" refers to the very early 7G pans that were all square and black overflow tube, then Mercedes changed them to have a beveled end and taller overflow tube (white). I doubt any W204 came with the non-beveled pan, could be wrong. Mercedes would replace the square pan with the updated beveled pan and white overflow tube during trans service.
Then with the "transmission pan upgrade" sold online people will install the 7G+ pans with green overflow tube on pre-2010 models (that originally came with the 7G pan with white overflow tube), but use the same red trans fluid. Mercedes does not perform this, unless you pay them to I'm assuming. My 2010 has the 7G pan and Mercedes did the trans service. My pan is rusting so I recently bought a new pan that has the white overflow tube.
