Turbo not kicking in

[Czar]

There is a vacuum pressure converter, located and attached to the underside of the inlet manifold, this vacuum pressure converter, controls the turbo wastegate actuation and pressure bleed balance, it is susceptible to oily gummy deposits, and as its a valve, these oily gummy contamination deposits cause the valve to stick and stop working, this situation can cause wastegate to bleed off all building boost pressure, giving the symptom of a turbo that doesn't work.

If in your case the valve was stuck due to the oily gummy contamination deposits, your hard driving will have created full vacuum pressure, therefore freeing up the stuck valve, my advice, would be to change this valve, it's inexpensive, and quite a common fault.

(Never had any fault codes when mine went either)

Any update on this? I'm still having issues, has replacing this worked, or can it be cleaned?
