The intercooler is usually situated in front of the radiator. The inter cooler is connected between the turbo and the air intake into the engine. It is designed to cool the 'compressed' air from the turbo charger. So follow the air pipe from the turbo to the front of the van behind the grill.

There is a diesel inter cooler under the van with fins on it, but they will have small fuel pipes coupled to it. This is coupled to the diesel return pipe to the tank and is to cool the hot diesel before it gets back to the tank.

You need a mechanic that has access to the citroen fault computer codes. The ECU can clear some faults when the fault has been identified and rectified, but some have to be cleared on the computer.  Some will try the old trick of disconecting the battery terminal for 60 secs with the ignition on, but you might have to get the codes cleared at a Citroen Garage.

If you haven't got the engine management code (key/password) then Citroen will get it from France but you will be charged for that service as well.

Robertphil has posted a good suggestion. Bearing failure due to poor lubrication is the most common turbo fault, but as Robertphil has said, turbo failures on the 2.0 are very uncommon.

when you last drove it did you notice the turbo working? some engines you never can feel it or hear it ,others you hear the turbo whistle and feel it  boosting you along

follow up where the exhaust joins the engine the turbo is jus before the engine.its awkward to get to unfortunately

if i was you id find who is your local peugeot citroen breaker and he would tell who is a good fixer . the breaker could also supply your bits cheaply

most towns have at least 1 pug breaker specialist with a yardfull  of bits. 

back when i was a spannerman i changed several of those engines that had gone bang (usually well over 150k mileage or overheated  and cooked ,but i never heard of a turbo blowing on that model

Spruce and Robert, thank you so much for your help and input.
Yes was driving fine before with no noises or loss of power.
I have tried calling a couple of mobile mechanics and left messages but not got back to me as yet.
To be honest I've been stressing out about this since last Tuesday when the obnoxious scrote who was delivering my vehicle back called me , fat lot of use that garage have been as so my insurers at keeping me updated !
Atleast I feel a little more knowledgable now as to questions to ask and things to look for, will just have to wait for vans return now.
If and when this gets sorted will let you know !
Thanks again guys

Just an update
Got my van back last Wednesday on recovery truck, was blowing black smoke when revved but driving ok enough to park it, test drove it Thursday , pulled ok up to 70 and no loss of power, so worked Friday and no problems.
It does have a rattling catalytic converter which I had planned to replace any way so have one on order and a mate to fit it.
 Could be really annoyed with this garage but more of a relief to have my van back and no big bills.
A lesson has been learnt, I won't leave things in the hands of my insurers and their prefferred repair center if I find myself in this situation again.

I have one of these engines fitted in my expert and last year started chucking out black smoke when on high revz. I took it to my local garage and I was fearing the worst and it turned out to be a split turbo hose from intercooler which I replaced and no more smoke and it runs a lot better now. Lots more power.

Worth checking.

Do these engines not have a EGR valve?

It's a common fault on the transits...
