No boost engine malfunction esp

[Luke1982]

Hi sorry for the long post but I'm stuck.
About a month ago was driving and engine malfunction came on.
Took to garage and injector 3 leaked
Changed under warranty as had them all done 2022 had the van back.
Was very under powered like turbo wasn't spinning.(turbo spins freely I've checked)
The usual engine malfunction traction light,no eml light.
Only code was p0299.
Took it back to same garage they changed glowplugs,egr said it was fine but even worse than ever.
Now has a horrible diesel rattle under acceleration.
Managed to take it to a friend who smoked tested it and it had crack on the inlet manifold.
Took it to a local transit breakers yard who also do work aswell.
Power seems back much less rattle but still engine malfunction and esp light which will come on first.
I'm literally stuck and can't keep throwing money away.
There saying possibly injectors still/pilot learn.
One thing I did notice when turning off sounds like a rattle from
Turbo actuator which is a black box type not a vacuum type
Unplugging it doesn't throw a code.
Any help or advice would be great.
It's a mk7 rwd 2.2 euro 5 crew cab tipper 160k

Forgot to add its been remapped and dpf drilled about 4 years ago

Air and fuel in - combustion - exhaust out - power from the process.
Air and fuel in wrong = no/low power.
Combustion wrong = no/low power
Ehaust out wrong = no/low power.

https://www.obd-codes.com/p0299
Forscan live shows FRP. and the readings of other sensors.

Catalytic break down = restriction.
DPF ash build up = restriction.
Internal engine wear can result in crankcase pressure = oil vapour taken in by inlet system = gundge.
Oil vapour + exhaust gas from EGR = lots of gundge after the EGR / inlet connection.

Is the EGR stuck open?
Is the FRP good - is there no inlet exhaust sytem restrictions?

(turbo spins freely I've checked) Do the vanes move freely?

Forgot to add its been remapped and dpf drilled about 4 years ago. - Remapped seems to mean HP output increased - if so usually results in more wear and tear. Deposits build up in the exhaust.
Now has a horrible diesel rattle under acceleration. Likely due to injection timming/qauntity - likely due to remapping.

It's a mk7 rwd 2.2 euro 5 crew cab tipper 160k. - Mk7 2006 to 2014. 2011 changes were made. Need to know vehicle year of manufacture.
Crew cab tipper has a payload of about .9 tonne.

Was very under powered like turbo wasn't spinning.(turbo spins freely I've checked) - Underpowered lots of posts re underpowered/limp mode/ no more than 3000 rpm.
Took it back to same garage they changed glowplugs,egr said it was fine but even worse than ever. - 160000 miles done. Not easy to get at EGR or glow plugs - lots of posts re both.

but still engine malfunction and esp light - ESP electrical stability program. ABS use the same wheel speed sensors ESP also has the steering angle sensor. ABS releases pressure. ESP applies pressure. Check wiring and sensors, reluctor wheel for dirt.

engine malfunction light - MIL multifunction indicator lamp/light - usually a DTC is shown/found when this general/warning indicator lamp shows.

ne thing I did notice when turning off sounds like a rattle from
Turbo actuator which is a black box type not a vacuum type - turbo bearing knackered is a cassette. Take off outlet from turbo - with finger can feel if to much play.

Unplugging it doesn't throw a code. Not easy to get at and unplug. Was it properly in?

There saying possibly injectors still/pilot learn. The 2012 E5 has self learning injectors.

Sorry year is 2013
Lots of that went over my head lol

It is either go to the specialists or learn it and do it yourself.

Buy a newish truck use it for 3 yrs sell it and get another newish one. 15000 for the first one. Bought at 5 yrs old sold at 8 yrs old. So you get 7000 for the now 8 years old one put that to the next 5 yr old which'l cost about 17000.
All pos' tax deductables.

Get a new one sell it after 5 yrs. Get another new one.
Just need the big outlay £40K and earn enough to live on and pay for the new/newish truck. Pay for the one you have - live - save for the next new one.
5 yrs - 8000 per yr. Save 8000 per yr. Live 20000 no hols. Could be done on 40000 per year income - the greed takes 20% of that so you'll need to work more to earn more to pay the 20% or go under.

Lease it ( beware of the small print) change it every 3 yrs. £350 / mth + + +.

Will look at new truck just need another 6 months out of this.
The actuator sounds so bad when you shut engine off
Done live data but not sure of the values
Do they mean anything to you.

I do not know much about reading diagnostic info'.

The turbo acutuator on mine makes noises at engine shut down - the EGR is also a noise source at shut down.

Can see that 80% is desired and that 36% is actual position. Which seems to be the vane position. How it is measured I do not know - could be 100% is closed or open. 36% could be 36% open from closed or 38% closed from open.
The votage reading can indicate the state of the wiring, connectors, actuator.

it would seem from the above that the vanes have not opened as desired - they are not 80% open/closed. Could be resistance on the vanes or and the connecting arm. Could be the voltage is low to/at the actuator. Could be the actuator motor is knackered.

Check on the type of turbo and actuator as fitted - should be the vane type possibly Garret. Some of the info does not apply to what is supposed to be on a 2013 engine.
The older type with a gate valve is pnuematic. The ones for the 2013 should be electronic.

Diagnostic tools need to be for that year make of vehicle engine.

O Riley has lots of vids DPF related. There is related info'.
In this vid can see diagnostic info' similar to your images.

Well hopefully found the problem.
The turbo actuator gearbox was broken,
I see one video that you have to relearn/calibrate it.
Any idea how to do this as I don't think my topdon 800bt does this

[tranmx2]

For a 2013 it could be plug and play.
You may find info' from the turbo manufacturer's web site re' that type of turbo/actuator.

Info ' on the web can be misleading - info' is often none specific.

It would seem that if the actuator gearbox is broken then the vanes are stuck.

It may be cost effective to replace the turbo and the acutator as a unit.

The label on mine is not too difficult to find.

Thanks mate viens move freely now so gonna try cheapest option.
Found a new actuator for free so gonna try that before replacing full turbo

[Luke1982]

Changed actuator full boost back can hear turbo spool properly and full power
Now got maf sensor fault. hopefully it's just where it was running without full boost has confused it

Clear/erase the fault codes and see what comes back.

Bloody saying p00bd now too much air along with p0299 underboost.
Can't win with this van
