That's correct. Once the latest firmware has been updated 2.86 onwards the vehicle will need a calibration file applying and this is generally only something a dealer can do - you can't do it using Diagbox as it needs to be downloaded from PSA servers directly.

Hi,

Can I ask you where can I find this calibration file on the SD card ?

For context:
The SD card of the RT6 of my DS4 1.6 HDI was faulty so I replaced it, I then installed back the 2.86 software and injected a user profile (found on the net) via mirascripts, everything seems working exept for the sound (cant even hear my radar warnings)
Meanwhile I managed to extract the files from the faulty SD with diskdrill and tried to inject my user profile with mirascripts but still no sound
I tried to mess with the audio config (set on HifiCAN by default) but still no results
But maybe I can find this calibration file you mentioned somwhere on the files I extracted from the faulty sd
+ HifiCAN could actually need a calibration file for it to work

Thanks for your help

The calibration file for Bluetooth echo is downloaded from PSA servers, I don't have any such calibration file, sorry. It's generally done by the dealerships. You may be able to contact your local dealer and see if they still have a separate copy they have kept from previous calibration work.

Thanks alot for the reply

Sorry my english isnt perfect I was unclear
Do you know where this file is stored once it's downloaded ? Or just the name of the file ?
Maybe I can find it in all the data recovered from the original SD card

No, the file is not stored anywhere. The file applies some calibration parameter updates to the unit software.
