I just decoded the CEM-pin on my V60-13, and then made changes to the configuration (Adding remote start for diesel-heater). Would this cause a problem in case the car need to go to a dealer, who will connect it till official Vida and Volvo database? I've understand it may be a problem on newer plattforms, bur what will happen on my P3 in this case?

Anyone have an idea?

@Martin-SE whenever a software update or reload is performed with VIDA, all configuration changes done with vdash will be reverted to the original factory configuration. Keys added with vdash will also be removed.

Thank you!

It depends I suppose. I have friends with remapped cars that went through official dealers and no issues at all.

@joroartcorp Mybe no affected software was updated or reinstalled at the dealer?

@joroartcorp remappings/tunes for the ECM/TCM and changes in the CEM configuration are two completely different pairs of shoes when it comes to software updates with an official VIDA.
Mappings/tunes are only overwritten/deleted when a reload/update for the ECM/TCM is installed.
Changes in the CEM configuration get overwritten with the original configuration known to the volvo servers with every software update/reload that is performed with VIDA for any ecu in the car.
Normal diagnostics or activating service functions does nothing/keeps everything as is.
Additionally most tunes/remaps create a permanent checksum error, which tells the guys working with VIDA that the ECM/TCM was modified, so they won't perform updates/reloads without consent of the owners.
All the above is only valid for P1, P2, P3 cars. On SPA and newer any configuration change/tune is detected whenever VIDA gets connected and can lead to a blacklisting for software and OTA updates until the original software is present in the car.
