One day I will get to the bottom of this problem!!
Last week my Shogun, after limping into p0299 yet again, it went to a turbo specialist, who diagnosed low voltage to the actuator solenoid but as his system didn't have the wiring schematics for this model, he couldnt be any more help and recommended I take it to an auto electrician and maybe get the ecu checked too. The eml had gone off when I picked it up from him.
So promptly arranged for an auto electrician to look at it who checked it over. As the eml had gone off, he asked me to drive it round a few miles to try and get it to come on but it wouldnt!It did show a p0047 turbo/super charger boost control solenoid circuit low. All wiring is good to the solenoid and the ecu. He said I should try a vacuum test on the turbo first. Then I should replace the solenoid if that dont work. Then finally if they both fail, I should have the ecu cloned but this would be tricky because of the location and security plate on the ecu.
i have tried searching for the solenoid but have drawn a blank , is it called something else? what do I search for ?

Well it pains me to admit defeat but Ive booked my Shogun in at the dealers Sad  Sad

So far it  has cost me-

visit to diesel specialist who diagnosed blocked map sensor pipe from error code p0299- £90
visit to another diesel specialist who told me to add some turbo cleaner- £45
2 x forte turbo cleaner £24
1 x forte intake cleaner £12
1 x wynns egr cleaner £8
1x new map sensor-£40
visit to local guy who showed me how to unblock map sensor pipe and cleared p0299 again-£40
visit to turbo specialist who diagnosed low voltage to/from actuator solenoid-£72
visit from auto-electrician/diagnostics who checked and passed the wiring from solenoid, ecu, map sensor, maf sensor-£100

It has been recovered a total of 7 times and not really sure what else I can do but let the dealership look into it as we use it to tow my daughters horse and box (which we havent been able to do since it dropped into limp mode with the horse and box on, in the hot weather, on a single track farm road!! Not a nice experience for my mrs and daughter!!)

This is our 2nd Shogun, the first one was 2.8 manual that we had for 6 years and never let us down, sold it with 260k !
This one we bought in Jan this year and for the past 2 months has been a total nightmare!

Skint Nathan

ps anyone got a petrol can and a zippo..........

Took Shogun to Stoneacre Nottingham, recovered to them with eml on and p0299.
stoneacre had the car for 3 days and called to say issue located and resolved, watch the video we have sent you, £230 please.
Turns out the issue they located was called something different to blocked map sensor pipe but thats what they did, poke a drill bit into the inlet manifold!
Car ran for 24 hrs and died again.
Replaced inlet manifold with a clean one. Died again.
Replaced boost solenoid. died again.

Any clues anyone cos Im about to burn the mf.... Crying or Very sad

You have learned the hard (and expensive) way that the dealers are not very good at doing anything but servicing.

Try giving Bullivants a ring on 01332 671000 and see if they can help.

They are very good at mending MkIIs and not overly expensive but I am not sure how good they are at the later models. They have been mending Pajeros/Shoguns for many years.

They are in Chaddesden, Derby

does anyone know if some sort of ecu remap, meddling or deleting would cause these issues?
would a dpf delete for instance start to show these problems over time if not done correctly, the egr has not been blanked tho..
really clutching at straws now..

No expert but as the blocked map sensor pipe keeps coming up what is the sensor that picks up this fault and can it be replaced or at a minimum the electrical contacts cleaned

Take the inlet manifold and EGR off, soak in petrol, clean with bushes,scraper,screwdriver etc internally. Clean out the MAP pipe and the fitting where it goes into the manifold, block off the EGR with a solid gasket.

Hi!
Have you eventually found the source of the problem? I experience the same thing and have been messing around with it for 10 months.

Replaced inlet, couple of sensors, renovated turbo… keeps coming back.

What Inexperience is that it losts lower when the rpm is low for a couple of minutes, when Indrive smoothly.

If you could solve the problem please share it!!! Smile

Thank you in advance!

PostPosted: Tue May 23, 2023 14:58    Post subject: Drilling the inlet butterfly valve Reply with quote

Hi,

I have been suffering from regular ~500 miles P0299 faults. I also suffered other faults that were solved by cleaning the intake and replacing the MAP & MAF sensors.
I have blanked the EGR and had the EGR mapped out at the same time as a 'stage 1' remap about 3 years ago.
The issues started some time after that.

I have found some links on the au pajeroforum (which I can't post because I'm too new), but they are quite old. I wonder if they are still relevant?


Drilling the inlet butterfly valve seems a bit drastic. Has anyone tried it?
