Hi, been a while since I posted, I've been having a good run up to now but it seems that's come to end!
So, the car felt a little down on power at low revs, fine higher up the rev range and the MIL coming on intermittently.
Codes read showing low boost pressure so I changed the turbo boost actuator solenoid, but still had the same problems.
With a vacuum applied by hand directly to the turbo it seems that the actuator rod moves only very slightly and with much more vacuum applied to it than could be generated by the engine. At idle the rod does not return to it's rest position, so I assume that the turbo vanes are always open, not allowing boost at low revs. Does that sound correct?
Is there a way I can confirm this without removing the turbo?
If I need to remove the turbo, is it possible to clean/ de-carbon the mechanism to get the vanes moving again or am I looking at a reconditioned turbo? Also can I remove the turbo with the IRD in place?
Many thanks in advance.
