since a garage changed the egr on my 1.6 tdci ive had no turbo boost. i have found its being caused by the actuator not working. i changed the boost solenoid at back of engine, no difference. checked the hose going into the actuator and there was no vacuum. i've put a hose from a fiesta on that i got hold of cheap, and now there's vacuum. unfortunately the vacuum doesn't seem strong enough to pull the actuator rod  down. i've felt the vacuum in the hose coming from the the pump on the side of the crankcase and the suction seems about the same there. to my mind it feels very weak, but i have no experience of this or another vehicle to compare it too. 

my brakes are working fine. i believe they are assisted by the vacuum pump too?

is it possible that there is enough vacuum being produced to work the brakes but not the actuator?

the actuator rod is easy to move if i push it down using a screwdriver, so i know it's not stuck

thank you.

 

This might sound stupid but is the rod connected properly at both ends as a chap i know had the same issue when he bought a 1.6 tdci and discovered that the rod wasn't connected properly as one of the clips were missing.

i will have a look, as far as i know the rod hasn't been touched so should be ok.

thanks for the tip.
