Have a 1.6 Grand C4 Exc, and exactly the same problem. Get warning messages for almost everything, and the car loses power completely. Infuriating that Citroen want £100 each time just to give their diagnostic, which tends not to be correct anyway.

Having the same problem with my C4 Grand Picasso Exclusive. Just put some DPF cleaner in, but the light still comes on and it loses power, but turn it off and back on and it drives normal again. I am at my wits end with this car; just one problem after another.

I have just bought a Citroen C4 Grand Picasso 1.6 diesel, and I will be contacting Watchdog, as I am experiencing the same problems as the last post.
I feel driving this car with the unknown fault is dangerous and worrying, and Citroen should be doing something about it.
The car lost power 5 times in 3 miles, and had the de-pollution system faulty message and light on dash.
Took it to a local garage who said it just needed a new fuel filter. 5 days later this happened. Not happy at all.
