Hi
Ref that throttle inlet motor , have got some data for that
1) Disconnect the connector, turn the ignition on , then on the connector , check the voltage on pin 6 , Yellow / blue Should read between 4.8 and 5 2 V?
2) With the ign still on , Measure the voltage on pin 1. Is it between 0 and 0.2 V , brown / blue
3) Then with the ign OFF , Measure the resistance between pins 4 and FUSE F17 Is it less than 1 0 red/ orange
Hope that may help

P132B-22
Hi All, since I last posted done a few more jobs and EGRs are now blanked with BAS Remap, however I still occasionaly get the P132B-22 code when flooring it up a long hill. Spoke to Pete at BAS who was very helpful and advise to check the electrical connection plug on the turbo for any signes of corrosion before moving towards a probabl actuator/turbo issue.
Can anyone advise the best way to gain access to the plug please? I am guessing through the side with heatshields removed...?
TIA>

To add some more info...
I followed the process described in the workshop manual to test the actuator...

So this was my reading at Idle...
And this was my reading at 3000RPM
So based on these readings compared to the 95% / 40% that the workshop manual advises there would appear to be an issue. The Actuator Rod is free to move easily So I am guessing it might be the actuator solenoid itself or (hopefully) the electrical connection to it.

TBH that doesn't look too bad Chris, try it at 2500rpm and you should see this or similar!!

I'd ignore the LR manual for this one as they are using different diagnostics so the equipment calibrations may be different. The live values above are from a perfectly running EU4 D3. As for the plug on the actuator it's behind the induction pipe of the turbo. So it's heat shields off and pipes out of the way to access it. You should be able to get at it whilst leaving the boost pipe in place!yµ (idµ - eAµ) ψ=mψ

Hi Prof,
Readings taken at around 2500 rpm... My engine was fully warm when taken so that presumably expains the difference in temp if yours was taken cold ?

Hi Chris
How’s it going mate , know ur in extremely good hands with @prof g , but out of curiosity what’s the live data at tick over for ur “ Boost pressure adjustment Bank 0 and “ Boost pressure actuator Bank 1 plse
Also don’t know if it would assist u by them being the same by changing the Map readings from bar to Kpa as it seems many of us have those settings
Many thks and fingers crossed is a simple fix
Ps, I’ve also been chasing the same kind of errors , hopefully some may assist u
Alas though I’ve still got to get round finishing mine so following urs with interest to what u ultimately find

Finally managed to find a spare turbo actuator connector I’ve got and took some pics for u
Plse don’t think I’m trying to teach u how to suck eggs but on the connector ur see a small rectangular cut out, want a screwdriver that’s flat bladed or pointed , no more than 3mm wide
Looking at the last picture , u just want to carefully raise that rectangular bit off the turbo actuator
Hope there useful to u as indeed understand it’s a right swine to get good access

Hi GS, seems to be the same as Bank 0 but with a decimal point, so 0.6xxx, 0.8xxx, 0.5xxx... etc. I don't think its too relevant.

Hiya
No probs and sorry got these wrong , should have been “ Boost pressure adjustment Bank 0 and “ Boost pressure actuator Bank 1
Only reason I mentioned it as mine came up on on boost pressure actuator Bank 1 N/A
Fingers crossed it’s an easy fix and pics also help u
Plse let us know how u get on

Hi mate, no worries any help or suggestions always welcome, I took off the three heat shields and could see the plug so just used a hook to lift the tab and check the plug, all looks fine with no corrosion. So took another look at the actuator linkage to make sure its free and it still feels nice and smooth, I took the chance to put my boroscope through it's paces so here is a video for you to watch might help anyone looking to do the same in future...
First I taped a bit of tube to the end of the scope and used it to direct some spray oil into the relevant places, then I used a strong magnet on the end of a piece of wire to push and pull the linkage, works really well and easy to feel if there is any resistance... Finally I left the scope pointed at the linkage and then ran the ignition through an on / off cycle to see how it moved.
Looks ok to me, so guess that means something else is F****d
(Apologies for the video I had to screengrab it from my iphone App for the scope as it does not save to my photos)

Boost air temp 44° Where are you the Sahara? That doesn't look right to me Chris!!
If that's the boost air temp from the intercooler there's something wrong in my eyes as I don't ever recall seeing it that high. I'm happy to be corrected but I would have expected to see a figure almost half that value, especially at this time of year.yµ (idµ - eAµ) ψ=mψ
