Hi,
I am trying to change an 5Q0919298K ECU (PLA2) to an 5QA919298B , which implements PLA3 and Maneuver Assist.
After changing the hardware, I am sure I have to adapt several codings in the ECU. Sadly, I am unable to see codings, adaptions and so on for said ECU. Info and Faults are perfectly read, log in is granted too, everythings else is giving me an general error (try again). History is working too - showing the old ECUs history and an obvious coding change form the old ecu to the new one, so the coding has been successfully read, too.
I am assuming that the ECU which is saved on the obd11 cloud does not match the ECU in the car (for sure it doesn't) - and this mismatch is causing this error.
Is there any possibility to reset an ecu on the obd11 servers?

Pushing this with some new Info: When tampering around, I was able to code the ECU blindly, so with old plaintexts:
Old ECU installed: IGN on. Start up OBD11. Connect to ECU 76, enter long coding (coding will show up) IGN off, remove old ECU, insert new ECU. IGN on. Change coding, commit changes. This works (also, most labels are still fitting the new ecu), but is not how it's designed. The list of adaptions is kept from the old ecu, so quite useless or even dangerous, as channel ids do not match.
As I have seen that it is not possible to delete and readd cars (with no history), this might be as complicated as the "whole car removal"

Solved: Deleting all Data and giving Obd11 a fresh start fixed it.

Let me get this straight....
...You swapped ECUs and didn't have to do any tampering with the immobilizer to get the car to start?

No. Not really. Just Changed the Parkassist Module If I am translating wrong - let me know which general Terms fits better than ECU...

I didn't read the title of this thread. At first, I thought you changed the actual ECU that controls Address #01 (engine) for which you would have to have a matching immobilizer. What you changed was just a module for your Park Assist, not the ECU. In either case, it is good to know that I understand what you meant , and happy that your issue was resolved.

I'm new to the Forum thing I am trying to reset my computer in my 2008 Passat back to factory settings across the board I hit something by mistake and is not starting only turning over can somebody lead me in the right direction? Possibly disconnect the battery? Not sure if that's going to do what I'm looking for

Hold on there. Post your complete scan of your car as it is NOW.
Then look at your first coding history for your ECU at address #1. This would have the configuration for you to restore to.
If you played around with the airbag setting (did an output test), then your car is bricked until it can be taken to the dealer to be reprogrammed and the airbag module changed. Also, I hope you haven't been playing with the immobilizer options and deleted any keys.
Your issue is a simple fix once you didn't touch the airbag module or immobilizer.
Please post a complete scan of your car with all uncleared fault codes.
