Hi don't know where you are but I had a problem when touring the north and was treated like a human being which is very rare in a garage I went to DonaldMacKenzie's in inverness and they repaired my 2009 ducato motorhome

In nw cheshire way, people I have tried have genuinely doing there best but the fault unfortunately still lingers, driving ok for a time then complete loss of revs at engine, no revs at all, can be stranded in middle of road, nightmare

Sorry mate I'm in south west scotland do you have any fault codes coming up

Fault codes, (read by mechanic) seem to vary from turbo pressure sensor (replaced) to fuel reg (replaced), now moved onto wastegate actuator, still losing revs, and power loss, thinking now accy pedal , not sure, potentiometer

This guy is just grasping at straws, don't know anything about cheshire but a quick search shows this:

Thanks for the link but by no means grasping at straws, getting sick of paying out and not fixing the fault, can only go on what mechanics are telling me, desperation possibly, fiat ****e

Wasn't having a go at you, you're mechanic sounds like he's grasping at straws, changing parts without having a clue. Wastegate actuator can be tested with a vacuum pump he should have one. Do you have overboost, underboost? A graph of boost, pedal %, desired fuel pressure, actual fuel pressure would have you on the right track the instant it loses power.

Great advice, but this is precisley my point, need a mechanic to read and understand data from ecu
