I've had all the other updates as said and none affected the performance of the car. I'm guessing they screwed something up with the AMG Drive Unit updates in your case, or possibly the ESP update. If the car had a power failure during the update and they didn't reset it, then it goes into limp mode for example. You can tell by bringing up the engine data screen in the COMAND system. I believe if it's in limp mode it will only show something like 200 possible horsepower instead of the 500+.

​​​​​​I Want to do this update because it would fix the no cold start after 3 days of not starting the car.

I am running a tune and my tune provider has given me a handheld to flash back and forth from stock to tuned.
Can I get the update and flashbit back to the tune?
Will it still flash to the tune after the update?

I spoke with my tuning company and they told me to flash back to stock then get the update from dealer, then to send them the updated ecu file to see if there is any conflict with the new update. If there aren't any conflicts the tune will work otherwise they said they will send me an updated tune that will be compatible with the new ecu update.

I can tell you from my personal experience, it didn’t change anything on my car. Much ado about nothing, but you guys might have different experiences if you’re tuned.

My car has RENNtech exhaust module as well. Again, noticed no difference.

My car has a armytrix downpipes installed and used to sound amazing and also used to preforme great with a lot of pops. Not anymore.

Can someone please advise me on how to get rid of this new software update from my ECU to how it used to be.

My car had no tune on my ECU before, only downpipes .
