2012 Mercedes R-Class R350 CDI 265HP Long
Thank you, I already did everything on the list this fall, including changing the Brake Fluid (right rear came out as black gunk) and I did a transmission flush with filter change in the spring.
Only fluid I have not changed is for the servo.
Anyone have specs on the servo fluid, and is there a filter in the tank/system for the servo on these? Just regular ATF?

You know you are not just dealing with a GOOD mechanic, but a real life GREAT mechanic when they manage to replace the sparkplugs on your Diesel engine.

I realized after it was a diesel car. I ment glow plugs. Spark plugs would be something. I actually forgot the R class even had a Blutech and CDI model.

Friend of mine had a Jeep Commander with the same engine.
265 hp in the highest power version, mine, luckily does not have AdBlue//DEF. It is also soft tuned to 305hp/700nm. Happens to be the same power I had stock in my old Truck, a 2003 GMC Sierra LB7 Duramax, with 6.6l of izuzu power. It was tuned to 460hp/1150nm.
The car really pulls with this engine.

Yes, the 350 CDI = OM642 = Same 3 liter v6 engine that was used in many Jeeps.

https://www.dimsport.us/en/race/my-genius/ <-- That is the same software I use. The tune was developed in Germany for my car, anyway.
It downloads the factory firmware and they modify it with the tune. They can also disable EGR via software, or remove the DPF (you can physically remove them afterwards without any errors)
It also tunes the gearbox at the same time.
