Help! P0246

[Heretic102]

Hi guys, new to the forum, I'm Martin.

 

Recently purchased a 2002 Citroen c5 hdi 110 with 65k on the clock, which to me was a bargain considering I got it for £1200

 

Having issues with it quite recently, first and most important is the turbo, the turbo doesn't seem to work when it's supposed to, the boost is there it's fine and more than less often it works on short distance drives, anywhere over 15-20 miles journey the turbo cuts out and stays out until the engine cools down over time(mystery), no strange noises or smoke. I had it diagnosed which showed up p0246 which supposedly is turbo pressure, not sure if I can provide anyone with more details but does anybody have any clues as to where I should start the investigation as I am a total newbie and have no idea what to look for, a bloke at the local garage has offered to inspect the pipes and "stuff"(his words) for £100 +vat afterwich he also said that it is more than likely that I will need to get a new turbo, but without investigating how the hell did he come up with that.

 

Thanks for any replies and help

turbo boost solonoid. as u look at the engine right hand side next to scuttle panel. black plastic cover held on with 2 clips. lift it up and youl see the solinoid. remove it and shake it if you hear a rattle its working and if theres no rattle its broke. check the rubber pipes going to it and the turbo

There is 3 of them solenoid valves, which one is it and how do you remove them from the mounting? Seems like a job

Took it on myself checked all the wiring I could access from top and bottom, bought a second hand selonoid valve which seemed to have a "rattle" in it, fitted it and still no success...what's next?

 

Cheers

Haven't posted in a while, jus an update, after having a Citroen specialist work on it a whole day with no success, whilst he was working on it trying to sell me a turbo, with the tip of my finger I felt a nail thin split in the solonoid valve pipe, changed the pipe and the turbo works like new again. The chap gave me back the £120 that he charged me for nothing and put the turbo which he had ready to sell to me back in the shed.
