Yesterday when I got into my car it took longer to start up. Thought that was weird but I just started driving as it was not idling weird, looked normal but then the CEL light came on. Nothing seems weird until I tried to hit the gas but the car felt sluggish.

I pulled the code and there were a bunch of them. Coolent sensor, camshaft sensor and also P0641 which I never seen before. Mind you I have never seen any code for the coolest sensor. I checked the coolant and it seems fine. After reading what P0641 is all about; I'm not sure what sensor or where the sensor for the transmission is located as it would seem that this code is sent for a drivetrain sensor.

I'm going to try checking the fuses. Has anyone had this problem and how did you solve it?

Also would anyone have the schematics for the w205/2016?

Thanks for the help.

Well Mercedes is stating that my ME Control Module is gone due to an engine modification. When I asked for more information and they state it's the Fan Module; which I find weird since i know you don't do anything to the fan connection for any kind of mod. Can anyone figure out how they can possible connect or mod the engine to a Fan Module or am I missing something? Reading online it would look like the ECU or whatever it's called can't or possible can't connect the the fan module. The question here would be, what is causing the connection issue. Either way, they state that my warranty will not cover it and I am looking at paying $1925+ Tax and labor for the part and installation. What I find completely weird is this. Why now? Why would the module fail after more than 3 years of any mods that I did to my car - PS. The engine is not modified except for blow-off valves which just vents air but does not do anything else.

So I had my ME replaced and drove around in Sport+ and guess what, I got the P0641 code again but that is the only code then however now I have P061A which is the weirdest code I have even seen.

So the car goes into limp mode but it does not do this if I'm in Comfort or Sport plus I keep loosing my Lane Assist and Blind Spot Assistance. It's a weird things and tiring at the same time.
