Hello everyone.
I just thought i would share this experience with you all because i hope it will help some of you out and prevent this series of events coming your way.
I recently was having issues with my 2.2D X Type where i would have flat spots under acceleration, kangerooing and simply lack of power. When this would happen my car would go into limp mode and i would have the flashing glow plug light come on.
My first point of call was to look for a turbo leak. I had the usual split intercooler pipe coming from the EGR valve. After fitting a new one the fault still existed. So i now replaced the EGR valve in case this was the problem... nope. After some brainstorming i moved on to the MAF sensor, nice and easy job and only £25. Still no change. Clutching at hairs i now aimed for my MAP sensor as the symptoms fit with hard acceleration, turbo pressure gets high etc... After a real struggle i managed to fit a new MAP sensor and believe me that was a struggle there is next to no space down towards the bottom of the intercooler hose. Much to my disappointment this did not solve the problem either... only to find that after all of this work it was my Turbo Actuator that had failed on me! This is apparently a very common fault with the diesel x type, s type and mondeos!
So to all if your car has the symptoms i described in the beginning of this post (loss of power, flat spots, hesitation, or kangerooing around 2 - 3000rpm) then i would try the turbo actuator first before putting yourself out for the rest of the work. The actuator is not a big job at all. Hope this is of some use to people!
