Wondering if anyone can help me, I am bringing my 2019 E63 in for service tomorrow morning and I need to revert it back to the stock file on mygenius, I thought it would be the same process as flashing the tune however there is no option under the work menu to write files. Anyone have any ideas ?

Yeah, buy a bone stock ecu for trips to the dealership.

Where can you buy a stock ecu?

MuffinFlavored

you need somebody (like a crooked advisor) to flash it for you

and there’s a chance tune flashes are stored in multiple modules

any mercedes part retailer (online)

mercedes parts of miami for example, great prices

I think you'll need to call or email them. They save your stock file and can re-load it for you just like they did with the modified version.

The Mercedes dealership.that's where I bought mine.

it doesn't matter will you flash it back before going to dealer or keep it tuned, a dealer can read logs of ECU flashing. As soon as you completed a flash tune you can't hide it except you bought new ECU.

Try to talk to your dealer and find out if they are tune-friendly.
