what is the exact error message? Have you looked at the records in History to confirm that the reversion back to the original values were done correctly?

hmmm.......... yes, I understand the general nature of your problem - but I can't help without specific error data (those faults could be caused by any number of reasons). Please provide EXACT error message that appears on the scan report  |

well....... as clearly noted in your scan report, both the central electrics module and the hex55 module are complaining that their long-code strings are incorrectly set-up.
So, now I need to see what changes were made

Wow- I have no idea what was being attempted with the changes in your History records and I can't follow the sequence.
But for the long-code strings on the 2 x problematic modules, I compare below the oldest Old value with the newest New value entries in the change records.
My suggestion: where you see a difference in Byte values - align your modules to old hex09/5F. This SHOULD fix the Control module- incorrectly coded messages.
Then clear the errors and re-scan

donHow do you get the list old and new value in your post? I only see the long coding in the obdeleven app. Are you used a hex to binary tool? Greats Daan

I don't understand. Here's an extract from OP's history file showing old/new value
--------------------------------------------------------------- Long coding Control unit: 5F Multimedia Old value: 1F7393010000000021110002000A02109F000125010001009E New value: 9F7393010000000021110002000A02109F000125010001009E Mileage: 125502 km Date: 2021-04-25 21:42:59 ---------------------------------------------------------------
Simply convert each Byte to Binary and arrange values in a table so it's easy to compare - not rocket science!!

You can also use my website to compare long coding values ( obd.itsezz.de/cc.html) It shows you the differences two long coding values in byte and bit. Below you can see the output for the long coding values of dv52 (Australia) 's post.  |
