Citroen C4 Picasso (B78) 2014 - Head Unit configuration file

Post by danlat1415 »

I have a 2014 Citroen C4 Picasso (B78)
VIN - VF7**************[VIN obfuscated, can be read by forum staff]

I updated the SMEG+ head unit system to firmware version 5.43.A.R2 a couple of years ago, and I know that it's meant to be connected to Diagbox by a dealer to have the configuration file updated (via a live connected version of Diagbox)
(I heard it has something to do with Bluetooth, but I don't know).

This is now the only fault remaining on my Diagbox scan - and I was hoping to finally get this fixed/removed.

I try clearing the code but it remains.


Is there any way to permanently remove the fault, or to fix the configuration file that it seems to be requesting?

I don't know what error you have or what code it is throwing up but a configuration file requirement should not throw up an error code. It's similar to setting your new TV to minimise the synchronisation delay between vision and sound. It's a configuration change, not an error.

Mirascripts my be able to change the Bluetooth delay but I have no information on how to do this.

We'd need the actual fault code to determine what the issue is. Pop up the fault from Diagbox.

Ok, so these are both configuration faults of the telematics unit and it needs a dealer configuration in connected mode to either check the configuration or to apply a calibration file. It's basically locked in secure mode which means you can't do it yourself as it needs connected access.

I thought that was the case, but I wanted to check.

It's not causing any issues with the system or the vehicle, so I'll leave it until it needs to go to a dealer (hopefully never).
