So what would be the solution for this fault? I have exactly the same issue, and hoping not to be ripped off by those that, as you say, pull out the parts catalogue and go crazy
Did the vacuum pump cure the issue on this car as I have the exact same symptoms with a car I have in Spain and I’m working with a limited tool kit and no miti vac but it does have positive pressure from the solinoid supply and negative from the brakes
The customer declined the repair as the vehicle was not worth much to him. The diagnostic was sound. Proof would be substituting the component vacuum with the servo vacuum, you should then get boost back
Hi changed the vacuum pump this sorted out the boost problem at low boost it still seems to have quite a bit of lag then at about 3k revs 4th gear on the motorway it will shut down in limp home with a low boost pressure fault then clear with ignition recycling the egr cooler seems sticky would this cause this sorry to hijack your post but I’m trying to sort this car while I’m over on holiday as I can’t get a mechanic over here who doesn’t want to just throw parts at it
You deserve a lot more views. Your a really good diagnostic technician
Good to see you back very good diagnostic and more videos 🙏
Good diag

This vehicle required a replacement vacuum pump, not to say that yours does with out carrying out a diagnosis first
Of course. Thank you, my friend.
