Please is there anyone out there who could provide me with a detailed diagram of where all thee vacuum pipes from the anti shudder valves and the turbo including the black box under the twin anti shudder valve. I have a ford focus mk 2 2ltr tdci on a 2007 plate . I have 3 electronic vacuum valves. One on the right of the head, i know that is for the turbo actuator i think. And two clumped together near the air con compressor.

I need to know know where all the pipes go starting from the main vacuum pipe to ? and so on. Also i need to know how these work. I assume when the engine starts the vacuum draws on the turbo actuator to open. How does the twin anti shudder valve work. left goes to the left side of the inter cooler and the right goes to the right side and the turbo. the left is open all of the time and the right is closed all of the time.

I would really appreciate some explanation and maybe a diagram as i cant find any literature on it.

Thank you!
