hi all I’ve got this proplem where the right side elm comes on at about 2600 revs but only when engine about half way on temp gauge. It’s an 05 td4 had refebished high pressure pump 6 months ago new low pressure pump filter at same time. Injectors replaced with reconditioned about 10 months ago. This has got me stumped. Am trying to retrieve codes but none come up when I scan cheap hand held scanner has any of you clever people got an idea. Am thinking may be crank sensor cheers for any helpful ideas

I'd get codes readbefore spending any more money. Good news is an eml will mean a code has been stored. Not sure what rpm the boost sensor works at but maybe wortha clean. That is the map sensor at front of inlet manifold. Report back with codes !!

Cleaned map sensor and can sensor contacts. Just pulled return feeds of each injector and all ****ing out fuel when fitted just a dribble so think I best get onto refurb company as they have only done 9000 miles. Will try and get codes but think they might just confirm what I think

Problem solved it turned out to be a bad refurbished high pressure pump. Had it tested and on strip down found a burr on pump shaft which was squaring the seals.
Cheers for all your input
