[Engine] Fuel issue
#1
2ltr HDI 2006 van. Whilst driving the other day the van suddenly would not rev beyond about 2K revs without dying as if about to stall. I decelerated and it ran fine below 2k revs. I thought it seemed like fuel starvation issue. Fitted new air and fuel filter next day but problem continued. The van starts and ticks over like a dream drives perfectly until you take the engine above the 2K revolution threshhold thats when is starts dying and surging. Yesterday I drove home on a fast stretch of road and booted it to see if it was a blockage. The engine struggled (dying/surging) at the 2K rev mark but suddenly the engine began to perform normally. Thought Id cleared it. Soon after I could smell diesel. Got home to find Id left a trail of diesel behind me that I discovered was coming from a fuel return pipe that appeared to have blown off a sensor on the return fuel line. Pushed it back on (its just a fricton tight pipe onto a spigot with no coupling) and it cured the leak but the engine was the same again (dying then surging then dying again beyond 2K revs).
I dont know what this sensor does or indeed if its anything to do with the problem but it seems that way. Any help from you expert gents as to what this sensor does might lead me to fathom it out.

Find lexia and plug it in.Read error codes.
If no errors than you have fuel line blocked somewhere.

Update: Local garage whilst doing MOT said my engine dying at 2K revs and surging dying is an EGR problem. They havent had it on a diagnostics machine just told me in conversation with the mechanic. He knows more than me about vehicles but it seemed a convenient thing for him to say as it was nearly closing time for the garage. Anyone got any tips on changing or cleaning the EGR on this 2ltr HDI 2006 van? Whats it like to get off anyone?

Seems that you can remove the EGR without too much bother, there are a few threads about how to, and a quick description about what it does here.

From what I've read elsewhere, the re-map is not actually needed. Might be a quick test to see if it's causing your problem. Although the fuel feed & MAF also seem likely culprits.

Thanks Cancunia
Good paragraphs. This might sound like a stupid question but whats the MAF?
What is so annoying with this fault is that it occurs most of the time but not all of the time. Drove the van today and it was doing it from the off then later it drove fine for five minutes then went back to being a pain. I think Ill just take the EGR off and give it an inspection and clean.
Thanks

MAF stands for Mass Airflow Meter like this but not necessarily the one for your motor but it gives you an idea what you are looking at http://www.ebay.co.uk/itm/Citroen-Berlin...7fPzpQ0RDA
