Can anyone help me with some info?

 

could be the solenoid that controls the turbo, vacuum pump or a vacuum leak. the rubber hose on the ends of the plastic vacuum pipes tend to split
the vacuum pump could be weak but still seem like it has vacuum.when the car starts the wastegate for the turbo should be pulled closed with the vacuum

 

Hiya, thanks for the reply, I have managed to borrow a "Mityvac" and have checked out the vacuum system and have no leaks anywhere, the wastegate actuator works fine, both on the mityvac and on the vacuum (have checked the vacuum and am getting nearly -30psi) from the car, have checked the vacuum solenoid and that works fine too, but the signal to it is alternating on/off every second or so, together with the signal to the recirc valve (so both solenoids are clicking in and out all of the time whilst the engine is running).

 

Anymore suggestions?

Please

 

Take it to vauxhall and get them to read the codes properly.

 

What makes you think they did not read them correctly when it went to them last week?

 

Any other suggestions, Vauxhall said that was the only fault code, I just need a bit of help in identifying the cause of the fault code.

Thanks in advance.

 

Have just tried a different inlet pressure sensor, with no difference, light flashing, wastegate and recirc both opening and closing, in time with the light flashing.

Any ideas anyone??

 

Take it thats a no then....
