hello I have a vauxhall zafira tourer 2.0cdti A20DTH 165HP. I have a problem with the vacuum system for some time. When I start it, the turbo vacuum valve is open and after some time, as the engine warms up, the valve closes and cuts off my turbo, what is the reason for this? Here are the errors that popped up on my computer P2263-5B and P2263-61 Has anyone had such problems?
