Hi guys having some problems with a 03 mondeo ghia x 130bhp 90ps tdci estate.

the turbo has stopped working so the car now performs like any non turbo heavy diesel car from the dark ages would.
doesn't hick or splutter when accelerating although mpg is quite down with having to use more throttle, there's no smoke problems out the exhaust, no noises, no warning lights fault codes or anything.

so have a couple of questions to ask

1/ what kind of turbo are they vacuum or electronic
2/ would an egr valve problem cause the turbo not to work (egr has been blanked off for a while)
3/ im checking through hoses for splits but could anything else stop the turbo from working
