Yet another problem with the Astra as always, over a week ago i had a new turbo put on, i drove it for about 500-600 miles on minimal boost, then i was out in it on Friday night, the car must have been on for about 3 hours then i let it rip.
It went how it should then when i powered on, i seemed to lose most boost. The car will still accelerate but without the turbo. (No warning lights came on)
Then when the car was left to cool down, then ripped again it went fine, then after a short time it went back to not allowing to use the turbo.
We put it on the tech2 last night, wiped all other codes (nothing relating to this fault), then i took it back out, boosted it and the engine warning light came on when i got to about 4k in 3rd gear.
Back to the garage and we change the MAF, the Sensor on the Turbo, and the Sensor on the top of the Intercooler / Bottom of the Power pipe.
The P1106 code still comes up with the error of boost pressure signal out of range.
Has anyone had anything like this before?
