Failed vacuum hose?

[Bren]

The actuator moves but is stiff without the hose disconnected.

That acutator looks electronically controlled. If it is, I don't know if I would want to manually move it.

[Bren]

I moved it a few times - after switching off the ignition the actuator moved outward.

[Noel Tidybeard]

you prolly need to uhhook rod off actuator and see how well it moves- it should be reasonably free

[Bren]

As it appears to be electronic I am reluctant to disconnect it in case I make myself more grief.

Mr muscle procured. Downpipe detached from turbo. I have jury rigged a dispenser to the can of cleaner of truly heath robinson proportions. However I have run out of daylight so pics tomorrow.

[Bren]

Removed exhaust. Pumped in oven cleaner. Reassemble and let tick over. Took car for a run - up to 4000 rpm and could not get spanner to illuminate. I even took a picture -

Lol.

 

Actuators can play up on these. Which you may have accidentally cured. Same as Turbo vanes. 

Misfire can be sign of hp pump failing, which is a pig.

Good old Mr Muscle, loves the Vauxhall's you hate

if it's VNT then 4k with no load is probably a totally different position for the blades compared to under load.

On a run to the caravan the light came back on. Tomorrow I will scan the codes with op com and check to see how dirty the boost sensor is - I googled cleaning these - surprising how dirty they get on a diesel.

[Bren]

Update.

 

My op com showed PO235 - Negative boost.

The boost sensor was filthy so I cleaned it and cleared the codes. 200 miles later no spanner light and car runs beautifully.

 

I checked the car for codes - no dtc's saved.

 

Hopefully I have cured it - the op com has already paid for itself.

Sounds good Bren.  The opcom really is worth its weigh in gold, can program keys etc too.

[SiC]

Not sure I'd trust a clone, especially the recent ones, to program keys. They work but can be flaky at times. You really don't want it loosing communication half way through the key programming process!
