Edit: I picked up my vehicle this afternoon. It was updated to software version 2020/03.58. All my coding was reverted back to original as expected after a dealer software upgrade. No noticeable changes as of yet. Last edited by mandomedic122; 06-24-2020 at 05:46 PM.. Reason: Adding additional comments and picture |

If someone did that and they think its the reason why the OTA isn't coming I suppose you can write the old FA back to the car. If you don't code the ECUs after you do that, you shouldn't lose your VO coding. Last edited by VTENGR; 06-30-2020 at 08:44 AM.. |

I think I was the first who reported this. I had 5AP removed and 8TL added and I swear I tried OTA at least 10 times and always got nothing. Immediately after putting everything back I got OTA. That was like less than 10 minutes after I tried OTA with modified FA. mandomedic122 had the same 07/2019.55 version and modified FA and couldn't OTA and wanted to verify my observation. Unfortunately he had some other more pressing issues with the car with the dealer upgrading his to 03/2020.xx.

For future reference, when you VO code, you do not need to write the modifed FA back to the car's computer. What token master recommends is that you make your FA changes, save the FA on your computer, read SVT/ECU, code the ECUs you need to get your VO coding to work. When you do it this way, you never technically change the FA on the car's computer. You're essentially tricking the car's ECU into thinking it has options it doesn't. This will work just as well as long as you don't code ECUs using the stock FA after you've done your VO coding. However, once you've VO coded, there would be no reason to code ECU. For any future VO coding, just load up your modified FA you saved on your computer and make any necessary edits. Now the question I have is can you take an FA file from 11/2019.70 and use it for 03/2020.40 and still be OK? I wouldn't risk it, but that just means you have to redo all your VO coding - which isn't that hard anyway. Just make sure you do your VO coding before your FDL coding. |

You can check this yourself by comparing your backups. Is there any difference whatsoever, other than if you change build date or options? I don't believe there is. You can even generate and use your own FA from scratch. |

This is exactly what I did. How do you write FA back to the car computer? To restore I read my backup FA xml (I diff'ed it against current with 5AP in it and no 8TL) and did what you mentioned above. I may be doing something wrong so it would be great to know how to do it correctly.

You have different coding options than your FA indicates, but I doubt the OTA pre-req checker would know about that. There are some codes that impact remote services so I guess that could be a possibility. I've changed codes that have prevented CD services from working, but seems unlikely and more likely a co-incidence. |

You asked about taking an FA from an earlier i-step and using it on a car that has since been upgraded. My suggestion was to review the fa xml files and that would answer your question. |

Oh - like a side by side b/w the two FA xml files. I'm not sure how to do that. I've compared NCD files by importing them into excel, but that's pretty tedious. Please be gentle, I'm still a relative NOOB when it comes to this stuff.

It's really simple. Just open them in notepad, and there' not much in there. I posted a framework above.
