Just wondering if anyone can help me or point me in the general direction.
W reg Astra 1.7 Dti, Izusu engine
No Fault Codes
The turbo will spool up but thats about it, the boost doesnt do anything, well it doesnt go into the engine thats for sure.
I got the car under the impression that the turbo had let go, so i changed the turbo, no difference.
The original problem was diesel leaking into the sump and causing the oil level to rise and causing alot of smoke.
So, that problem was rectified but the issue with no boost remains.
I chexked the vacuum from the pump on the back of the altenator and it seems to be a good vacuum, ( only visual checks) this then supplies the waste gate actuator solenoid (not sure if thats the correct name) and i get absolutly no vacuum coming out so i changed the solenoid for a known good one and this was exactly the same, good vacuum going in, nothing coming out.
Any help is appreciated
