I guess you have an HDI engine (possibly RHZ) as this fault is very common on that model. Quite possibly it will just disappear. It is not likely to be the turbo. Swap the electrovalve (pneumatic solenoid) which controls the turbo with one of the others (there are three beside each other on the inside of the wing, and see what happens. If the fault moves elsewhere that confirms electrovalve fault - so replace valve it.
If not check the vacuum hoses and test things such as the EGR for vacuum leaks. Another possibility is a faulty (or even just dirty) MAF. This is very easy to remove- it is on air intake - so remove and clean with wWD40 or similar.

It is on the passenger side of the engine compartment under the wiper panel. its deep in because of the body design. you'll see a relay box. It should click on and then quickly off when the key is turned to run without starting the engine
