Hi Drifter. Thanks for the reply. The overboost isn't constant, it mainly happens if I accelerate hard between 3to4000 revs. You can hear the revs increasing but the drive doesn't match the rev Increase. You need to tap off a bit and then the drive takes.
I get a service light which goes away...
Hi Nether. Did you ever manage to find the cause of the overboost condition. I have a 2013 kuga and am experiencing the exact same thing. The mechanic seems to think it could be caused by a slipping clutch?
