Hi All, Quite new to this forum and looking for advise on the following :

I have a 54 reg 525d thats done roughly 79500miles recently it has started to cut out the turbo when the car is warm after about 15 mins roughly
when cold all is fine but once warm it seems like somthing is telling the turbo not to cut in the car is a bit jerky at about 2000-2500 revs but carries on just normally aspirated. Once cooled down turbo again but 15 mins later gone again. any ideas ?
cheers
