So I started seeing messages show up on the dash, similar to what this person experienced in this thread: https://mbworld.org/forums/c-class-w...w203-c240.html

I took the car to the dealership and they state that they need to return the car back to a stock file in order to be able to test the CANBUS properly. Does this make sense?

I have had this tune on my car for two years without issue, but if the car is returned to stock Im sure it will be running rich as hell. And I dont know if Jeremy will have the file from two years ago, which will likely cost me more money to get it re-tuned ( I really like this tune)...

Anyways, is what the dealer saying accurate? DO they need to return the car to a stock file to diagnose?

Is there any way to pull the file off the car or will I be forced to re-tune. Will it be safe to run on a stock file until I can get it re-tuned?

You can send Jeremy your ecu and he can save the file and then return it to you later

I didn't know that, though I really don't want to be down that long.

Email him and see if he still has your file, of he does then obviously no worries but if he doesn't there is no other way

Quite impressed with OE's support. I sent sales an email and they responded within 10 minutes. Jeremy advised that he saves ALL tuned files and once I send the base file to him that the dealer loads he will be able to send back a file that has my current maps etc merged to the new base (in case there is new code in the base file).

I went ahead and purchased the mygenius flashloader which they then overnighted to me so I will be able to flash the car at the dealership once they are done with it.
