    Default Turbo Problems

    Hi there... this is my first post on here so be gentle with me!

    I've got a Signum 2.0T with a superchip remap... the other day i noticed the bypass valve didn't seem quite right... louder than usual and then yesterday the engine warning light came on and the car has gone in to limp mode... now i've got no turbo boost what so ever.

    After some research it appears it maybe a common problem and a clean of the bypass valve with some carb cleaner should sort it.

    Anyone else experienced this?

    Any help greatly appreciated!

    hi mate,

    highly probable that you have a turbo solenoid issue - there are 2 of these .. one is mounted on the top of the turbo - the other under the ecotec cover - i would start with both of these bad boys - but to confirm it get the fault codes read first -

    did you read the codes first - theres no point changing them if the fault is NOT related
