Citroen C8 losing power

"Our Citroen C8 2.2 diesel (2008 model) has developed an intermittent loss of power, which triggers the engine management light to activate and a DPF filter fault to be displayed on the dash. Our local Citroen dealer has recently replaced the fuel sensor and related injector rail; however, the fault has again surfaced and due to daily motorway family commutes this irregular loss of power can be quite alarming. Any idea what's causing this? "
This has an Eolys fuelled DPF so I would guess that the Eolys fluid is depleted and needs replenishing and I can't figure out why this has not been realised by the Citroen dealer.

Faulty used car - can we reject it?

"We bought a used Citroen C8 two weeks ago on the understanding that the cambelt had been changed and that proof of this would be forthcoming. However, the garage has still not provided this, plus the day after car was collected the windscreen washer was found to be not working and garage take no responsibility for the fault as they insist it must have been working on collection. This is going to cost £100 to fix. Can the car reasonably be rejected as faulty or could the garage be forced to repair the fault. "
Yes, the car can be rejected. Law here: The two issues might even be related:

Cambelt failure on Citroen C8 – should dealer pay for repairs?

"I own a 2004 Citroen 2.2-litre C8 HDI, which I bought from my local franchised dealer in 2005. The car recently broke down on the motorway and the dealer told me it had suffered a cam belt failure, which resulted in catastrophic engine damage. I have read the HJ forum about the issue of cam belts failing with C8s and it appears to be common knowledge. Is this something the garage should have checked and reasonably been able to spot as part of the car’s full service? "
This is a well known fault on the C8, so yes, a Citroen francised garage would have checked. See: Your problem is that you have not had it serviced regularly enough, and you had it serviced by an independent garage that probably did not know about this problem area.

Citroen C8 additive warning light

"I have just acquired a Citroen C8 and a warning came up on the panel that the diesel additive needed attention, and to get a local dealer to look at it."
It needs the Eolys fluid that replenishes the DPF topping up. This is in a tank and is injected into the fuel each time you fill up. This is a specialised job.
