power loss

Hi All
I have been an avid reader on Landyzone for quite some time now and have picked up some great tips, thank you all!!
It is now time for me to ask for help!
I have a problem with my 2005 TD4, when the engine is at full temperature the engine management flickers on and off and the engine starts to misfire, intermittently, when I slow down at a junction/roundabout, the engine dies and cuts out (which is frightening - no powersteering or brakes aaaggh!!). I have cleaned the MAF and also tried driving with the MAF disconnected, but no improvement. I have plugged in my mates "CAN OBD 11" diagnostic, but no problems found? Any help would be very welcome

You need to look at the live data. The low pressure pump should be over 350kpa at idle. Much under 320kpa and you'll be needing a new fuel pump and filter.
The high pressure fuel rail should be circa 30,000kpa at idle.
I'd be checking both those pressure readings for starters.

I would start looking at the fuel pump and change the filter as well.

OK thank you very much, I will let you know how I get on.

Hi Thanks for pointing me in that direction, it turned out to be a fault on the low pressure sensor. Stripped and cleaned it, cleaned contacts and hey presto. I have changed the filter as well as it was obvious that had not been changed in a long time. Many thanks for your help
