Hi. Well my 1.9 120 2006 multijet has occasional serious loss of power. My fiat garage says injectors but the weird thing is I live in Dover and drive in france a lot. When I fill up in france my engine failure warning light goes of about a mile out of the petrol station. Then back in uk once I fill up about 20 miles later loss of power. I have tried all brands of diesel in uk regular and super. Occasionally weirdly murco, jet and texaco work a bit better. BP ultimate diesel immediately seems to ignite the engine failure light and loss of power. But like I said never a problem with French diesel. Very weird question but does anyone have any ideas.
