Ok - I put a vacuum gauge on the vacuum source going to the wastegate and went for a drive and pushed the engine hard trying to get the turbo to engage.

When the engineer first starts there is a moment of vacuum then the needle went to zero. The needle stayed at zero during the entire drive - not moving. Once I stopped and shut the engine off the gauge showed a vacuum which slowly bled away.

Sounds like the EDS not sending the correct signal to the vacuum source?
