No turbo vacuum running to actuator - 1.6 hdi 90 
As title.
Turbo not engaging at any point and it's become a nightmare up hills
Actuator not moving was first sign so put a silicone hose on it and did a basic test to see if it moved and held air and it held so realised that's ok. Pipe to the actuator is not getting any air going through it so i thought is the electrovalve dead on it. Replaced and blew through pipe to actuator to ensure its not blocked. Both made no difference so what next in terms of finding why there is no boost?
It is letting off smoke from that area on a high rev so carbon build up is not helping so makes me wonder if the cat is blocked in some way?
Doesn't help soon as you hit 3.2k revs it bounces back as if it's misfiring each time but i wouldn't know where to look so yeah, any help would be smashing. Thanks. :thumb:
oh and fyi, no fault codes via diagbox.
