Hi all, without using my brain I just messed up my central control unit. I have now several errors and blinking warn lamps inside my speedometer...  How can I undo my changes (see screenshot)? How can I set the old value as new again? Many thanks.   |

Post the history of the changes you want to undo or you can use my website to show the difference between two hex values. (It's in my signature)

I would agree that his tool is very good and i have used it many times. Last week I found that OBD11 Also has a help function in relation to this. From your history view if you click on the coding it takes you to the long coding screen and it highlights in GREEN the Bytes that have been changed. If you then go to that byte you will see the actual bit or bits that have been updated. In this example from my car you can see that Byte 11 has been highlighted in Green and that Bit 4 was the item that was changed.
