davd Posted July 12, 2011 Share Posted July 12, 2011 few problems i think! on starting cold, its spitting and farting, missing ! once warmed up idles ok , but missing a bit! knocking sound when pulling off, not the tensioner noise! sounds like injector knocking! and 2nd problem is, boost pressure i think! got the code read and it was boost pressure problem! when im driving from cold and have the turbo come in ,power comes through then suddenly into limp mode,glow plug lite comes on! i switch off and on again and lite goes out and carry on but got to be careful not to build up high revs whilst driving because once turbo kiks in if i carry on accelerating to high revs turbo cuts out and goes into limp mode????thus im not utilising the full revs and power! but once the motor is properly warmed up i have no problems at all??? the injector knocking is always there but is reduced once the car is warm! how do i know or test which injector is gone??? and is it a common problem associated with a certain number injector,be it 1 ,2 ,3 or number 4 injector? with regards to the turbo cutting out,iv been told it could be a gummy turbo or it could even be a leak or it could be a sensor??? how do i nail this problem or narrow down the fault finding, please help!!! david Quote Link to comment Share on other sites More sharing options...
mintalkin Posted July 13, 2011 Share Posted July 13, 2011 check and clean if required the egr valve,also check the intercooler pipe on the bottom of the valve for splits. if you have an electronic acuator on the turbo check to see if the arm moves back and forth when started.

mintalkin Posted July 18, 2011 Share Posted July 18, 2011 it could be a clogged up manifold some good info here, http://www.google.co.uk/search?btnG=Google+Search&q=mondeo+tdci+manifold+clean] if you think its an injector you could try recoding them as the delphi injectors can loose there codes, NOTE: The injectors on the label are in firing order, NOT physical order. The top left code is Injector 1 (Cyl.1), the top right code is Injector 2 (Cyl.3), the bottom left is Injector 3 (Cyl.4) and the bottom right is Injector 4 (Cyl.2). Where Injector is the firing number, Cylinder is the physical number. When replacing an Injector the code stamped on the body of the new Injector must be programmed into the PCM, NOT the code on the label. also if the noise improves with the engine warming up it could also be an injector with a low load fuel delivery problem, but this can only be tested by removing the injectors.
