No. We don’t taking any kind of responsibility when you doing firmware / maps updates on your own. Why?We don’t know what exactly you have done, how did you prepare SD CARDs, how did you perform update or what changes have you applied in hidden green menu. 

Some people has blaming us that after maps updates, their car engine doesn’t work like before 🤦‍♂️
(doesn’t matter that’s completely two different control units..)
ECU & MMI module (5F) are not the same!

So if you are looking for free car service from us, just try somewhere else.. 😉

We only taking responsibility when we are installing those updates in your MMI.
