Hello . I own a ford focus 1.8 tddi 90hp from 2000 that I mostly use as a beater car . My dad owned the car for like 12 years or so , currently having 320k km . The problem I have is that the car loses power all of a sudden , like the turbo is not kicking in, even if I can hear it working . When I start the car it works very well , but after one km it just cuts my acceleration , and the car will run very slow , like I can't even past 120km/h with full throttle. If I stop the engine and then restart it it will work good for another km and then loses power again. I can feel how the acceleration gets cutted .
Any idea ? I have no intake leaks . 4 years ago the pump broke , but I changed it and now I have no problem with the pump . The car run like it is in limp mode . No dash error. Any ideea ?
