A hopefully quick question. This came up on my 2021 DS Express 5.7 Quad Cab about a week ago.
I've searched the 'web and this forum and seen many people stating it is the under seat plugs. I'm going to try those in the next day or so.
The fault comes up randomly and also goes away randomly.
I haven't used AlfaOBD yet as it requires the security patch harness and I didn't want to do that yet until the selling dealer took a look.
So I took it to the dealer last week, they plugged it in and gave me the attached printout and told me it wasn't covered by warranty as the radio isn't original. After me asking why the code only just came up now after the UJQ 8.4" screen has been there since February or thereabouts, and if the original radio had anything to do with the airbag system, and then getting nowhere, I then took the attached photo of the printout and thought I'd ask here. Their argument was it says "radio" under ECU so just thought I'd check that here first.
It is going in for its first dealer service next week, and I have to pull the UJQ out anyway to replace the delaminating screen. So I thought I'd put its original radio back in and see if the errors go away or not. If they don't I then can try to get them to get their head out of their backsides and figure out what the problem is rather than simply fobbing it off as my fault. Unless it is the UJQ's fault? Do I actually have to get into the BCM and change the type of radio installed? It was an easy plug and play radio swap apart from having to change the centre console media hub, as it still has the Infotainment adapter bezel and MTC aircon setup (I haven't changed it out yet to mpgrimm's patch harness and single zone ATC bezel). It has worked flawlessly for 6 months or more other than the screen delaminating slowly.
