No, there are major issues at present with the PSA Updates - as in they are not working properly.

You can either wait, or provide your VIN here (Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff) and I'll provide the links for you to download directly.

By the way, your C3 has an outstanding After Sales Campaign that requires the Engine Management ECU to have a software update, so I suggest you get it booked into Citroen to have it done. The work is free of charge. Quote reference HTM:
HTM - Engine software
The operation involves downloading a new software version into the engine control unit.
RCC Firmware

When you have extracted the firmware files to the USB there should only be one folder in the route called SWL and a single file in the route of the USB. All the firmware files are stored in the SWL folder. Do not allow your zip file utility to create the long firmware folder name on the USB to extract the files to or the update will fail.

However, as your C3 doesn't have on-board WiFi, you will need a licence file before the unit will allow itself to be updated. When you have completed the above, create a new folder on the USB called licence. Extract the content of the licence file download into this folder.

Hi, thank you for the link, do you have anymore information on the Engine Management ECU software update as this is news to me? Is it 100% free? How is it effecting the vehicle?

Hi again and thanks for the link, I downloaded both the licence and RCC firmware from the links you provided, I extracted RCC Firmware zip file, there is a folder named rcc_update and another named UpdateInfo, I take it these two need to be on the root of the USB pen drive along with a folder named licence with the licence file inside, is this correct?

Or do I actually crate a folder named SWL and copy the content of the rcc_update folder into the SWL folder I created?

Thank you.

Ok, so on the root of the USB stick I now have two folders and one file named UpdateInfo, one of the folders is named licence that I placed the ATOJAR Licence file in and the other folder is named SWL, this folder contains twelve .bin files, one .cms file and one .xml file.

I hope this is correct.

Thank you.

Yes that's it.

No further details on the after sales campaign - it's when they detect an issue with some vehicles and have updated the software to account of this, so should be updated as soon as you can to prevent any issues. Yes it is free.

Thanks for the heads up on the ECU software update, I would have had no idea otherwise, I contacted my local Citroen dealer and they where super helpful, my car is booked in to get the free ECU software update early next month, Thanks again.

I will be updating the touch screen in the car over the next couple of days so I will repost back how it went. Thanks again.

You mean you have a blue screen? Where? On the instrument panel or the large touchscreen display?

You shouldn't have a bluescreen and if you have, take it back to the dealer as it will be under warranty. I doubt a firmware will fix this issue....

That means it is in the middle of an update already - so I would not interfere with it or switch the vehicle off during the update!
