Did you use the ‘clean my drive’ app on the usb stick before downloading the files? Perhaps you need to try another flash drive to see if that makes any difference!

2. Options
3. System settings
4. System info

I too updated without any issues which was a surprise considering previous attempts from my Mac downloads. The update link straight to my flash drive worked seamlessly this time, I even went for a drive round whilst is was updating!

The app also me to log in but doesn't reco...

Hi, welcome to the forum!
I too am a long time Citroen owner, 2CV Charleston, GS Club, Xantia, ZX, BX, DS3 and my current C3 Aircross. I think my all time favourite is the 2CV Charleston, I wish I'd kept it! I've always wanted to own the Traction Avant.

Hi, It's nothing very important just annoying! It's regards the Citroen App on my iPhone, I keep being unable to log in, it asks for email and password but it doesn't recognise these even though they are correct; I even try and go through the 'forgot password' link and redo it, but it still doesn't ...

Apart from the computer generated reply, I’ve not received a response from any of my queries, which makes me wonder if there’s anyone looking at them!
