    Astra Coupe Turbo Problems

    Hey guys, i was driving about in yarmouth last night as the turbo just stopped working, its seemed once the car was at or above 90 degrees, the turbo would decide not to boost?? took the car for a drive to cool back down to 80 the the turbo gradually started to boost back up again!! basicly it was like driving a 2.0L about for a while. My boost guage would boost from - to 0 but wouldnt go abouve until the car cooled down!!! any sugestion??? some mentioned the recirc valve diaphram could be split??

    Have a look at the position of your wastegate when the car is cold. Then go for a drive until it stops boosting and have another look at the position, it should be in the same place....

    this hapend to another member last week.. the actuator rod was catching the precat clamp.. as said look in that area as it sounds like ur actuator or wastegate is stuck... doubt the temp o engine would caus ethis tho when u think it says 90 thats the engine temp.. ur turbo is well over 300
    The coupe...ITS ALIVE & back from the dead....again!
