Hey all,

I was just uploading a revised tune from my tuner, MPT, and while going through the tune process i got this error and the trunk wont start and errors flashing on dash.

tried loading up the previous tune and the stock tune. all of which return the same error.

check if there is some kind of update with RTD connected "RESYNC" A lot of paperwork has been described on this topic since the writing error was very common in the past. Based on various research, I wrote several essays and published them on https://paperap.com/ I hope it helps someone. As a rule, over time, the most common errors become irrelevant and the error of the letter has also already been resolved by many. But I hope the data from my work will help you.
