i have a 2.0 galaxy which is doing the same i recently took it into my main dealer where i got it from and they said that with it going into limp mode means that the turbo is getting clogged up with soot. so they took it out and drove the car at 4000 rpm doing 60 or 70 come back and it was great like a new car. but recently my engine management light is on and of like a yoyo i was sat idle yesterday for like ten mins got two secs down the rd and went into limp mode. am very disappointed with the car doing this as im beginning to wish i never bought the car. was thinking of maybe contacting ford themselves as its only 3 yrs old.
