The ECU monitors all kinds of data, if it detects a problem, for example "knock" it may "back off" the amount of fuel injected, irrispective of the amount of throttle, It may decide to put the car into "limp home" mode, this is to protect the engine and to keep you going to get you home. The ecu knows how much throttle you use, how many revs Hi, first post of a new member. My daughter's Fiesta 1.4 TDCi 2008 (mark 6 facelift) has some problem that I am hoping someone can help with. When she bought it the car seemed fine but on the way home (motorway driving 70mph) I noticed about 6 times the car would lose power for less than a second and then recover. Focus TDCi 115. Just taken our car to an alternative dealer (OMC Ford, Oldham). The car had an ECU update and now the accelerator is easier to judge and the overall drive is much smoother. OMC said as soon as they plugged the diagnostic equipment into the car, "urgent update required" showed on the screen. I have recently taken my 2014 1.6 tdci to a tuner, they asked me to re-connect the battery after putting the ecu back in, after mapping. The car starts but runs very rough for a couple seconds and cuts out. Fault codes show - Faulty fuel injector driver within the PCM Could this be caused by conn Posted December 9, 2012. The connector is secured by a screw (bolt) with a head that shears off when fitted. To remove the headless bolt it has to be drilled out. The official way is to insert a sleeve into the connector hole with a smaller diameter hole in the centre to guide a drill bit. Maybe you could improvise with a bunch of washers.
Hey Adam, months back when I got my mk6.5 fiesta zetec s 1.6 TDCi it was left on the driveway for 2 months and was driven in and out the garage until my insurance renewal came up for my previous car. At one point the engine light came on and the code was to do with the Egr. Try deleting the code with the diagnostic tool as I deleted the code
Ford Focus TDCi - Ford Focus 2010 TDCi 1.6l Turbo Issues - hardway Have to agree with elekie doc on this one. If the mil lamp has come on then the cars computer (ECU) HAS detected a fault and switched the lamp on so there must be a fault code registered! Has anyone found a solution to this, my 2009 focus CC 2.0 TDCI ( 85,000 miles) is doing the same, "Engine Malfunction" light comes on and the starter motor doesn't operate, fully charged battery. The first thing happened a few days ago, after freewheeling down a 2 mile slope a warning light came on saying " acceleration limited" and the car was These codes do not always indicate a problem, and can be caused by normal diagnostic functions, carried out on the vehicle. ===END PDM DTC U1900-20=== ===DFDM DTC C198F-20=== Code: C198F - Lost Communication with Switch Pack Status: - Previously Set DTC - Not Present at Time of Request - Malfunction Indicator Lamp is Off for this DTC Module NpSffY.
