206 1.4 hdi turbo cutting power fall

First of all hello ... my car is the 206 1.4 hdi van model. My car, which is at 240.000 km, cuts the turbo at serial departures before it comes to 3 thousand cycles. Because even if I suddenly have a muscle in the car, and the gas goes to the type, the car accelerates very hard. At 150km / h, the car cuts off again. What could be the reason?

When I squeeze the turbo pipe with your hand and give gas to someone else, if the sysmyous goes off, it is okay. If it doesn't, there is a problem. Try it. But I did not try it.

I can't get off my ramps with 4-speed ramps for 5th gear 90. I always get a little lifeless at 4 to 70 in the lower speeds, but I don't listen to it when I have one or two people.

Look at the turbocharger hose to see if there is any oil or oil. Bid in turbocharged turbocharger, the size of the vehicle is nearly full, if it is used in 240 thousand straight.

Thank you very much, I will apply what you say
