Hello, after having used the search tool without success, I am contacting you here to share with you my problem.

My Primary Turbo charge properly, either 10Psi (0.7bar), the Secondary has him several problems, as soon as the engine is lukewarm, it loads at 7Psi (0.5bar), but the moment that the engine is warm, the pressure has a tendency to drop a ~4.3Psi (0.3Bar) at the opening of the latter, has 4500rpm so..
At that moment the pressure has trend reassemble, when I kick the gas pedal.

The fault is intermittent of a moment at the other the secondary can load again at 0.5bar, 7Psi (0.5bar).

I therefore have two problem, a pressure already too low has the basis (7psi), which has a tendency to fall through time even more bottom (4psi) when the engine is warm.


I also had another problem which is no longer returned since that i have replaced the Thermostat (the old had been deleted), when i turn on the A/C to turn on the cooling fans. I also had the problem at the secondary, I have not been there faced a new, but may be linked..

Thank's in advance, "Merci"
Sorry for my bad English..

Now here is more than 6 months that I work on this car, a long list of faults repaired. So, I saturate a bit
