Can anyone shed some light on this matter?
I went to ford dealership to update my cars software but apparently there are no updates available. I have replaced glow plugs. OBD reader showed around 400bar fuel pressure while experiencing the problem. EGR has been replaced a few years back with AliExpress part but no error code.
It seems for some reason the car starts better when I hold the clutch down and 50% throttle.
I have found this on forums which seems to describe my problem.
Car - Ford Mondeo MK3 2.0 TDCI 85kW 115HP 2003.
About 250000km and manual transmission. No codes other then some EATC ones.
TSB 34/2006
Ford service bulletin 34/2006 dated 14 dec 2006
Should a customer express concern about low idle speed (500-700 rpm) and or no throttle repsonse for between 2 second and 3 minutes depending on vehicle, the probable cause is the minimum drive pulse (MDP) of the injectors, which has drifted excessively at low rail pressure (less than 400 bar). This causes a reduction in fuel delivery versus demand and stops the engine reaching the required idle speed in an acceptable time. The PCM does not detect the excessive MDP drift because the strategy does not learn the MDP at the pressures where the problem occurs.
After some time the idle speed will return to normal (800 rpm) and throttle repsonse will be obtained. This concern can occur when the engine is hot or cold. The issue is recurring.
To rectify this concern a new calibration has been released for service which will vary the quantity of fuel demanded during engine cranking in order to reach the idle latch speed in an acceptable time.
I would try to find a Ford dealer that would recalibrate it problem is most of them don't like working on diesels some don't even have guys that know how to do it right
Thank you for the answer.
Since it's not a software issue it's probably the high pressure fuel pump or injectors? Would a pressure test for both be a good next step?
Thanks
