iv been having a few problems with the turbo on my car when you are driving along and hold the car at 3000 rpm for a while all the turbo power dies and i need to restart the car to get it back. was wondering if anyone could give me some advice on what it could be?
Get the ECU read with VAG COM to ensure that all the engine sensors are functioning correctly and there are no fault codes saved on the ECU before you start buying any parts.
Possibly sticking vanes on the VNG turbo. If the ECU sees an overboost condition it will go into a "limp home" state. Getting the fault codes read should point you in the right direction.
