Hi
This car came to me with an issue related to the turbo.
The car was low on power, and when under load would light up the engine light and would go into limp mode.
The car had the codes cleared before came to me, and I did not went to a test drive, so not sure which codes were being triggered....
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

Your work is fantastic. I have watched you repair Renaults, Mercedes and Toyota vehicles. Absolutely fantastic. The way you remove Eeprom chips as if they are batteries is unbelievable. You are one of the best vehicle electronic repairers I've ever seen.
😊
Comment really appreciated!
Thank you very much!
👍👍👍👍👍
Thanks to your awesome video I was able to do the job myself, the most difficult was, like you have said, taking down the damn 10mm nut, I did it like you explained!
Thanks again!
That's great!
Well done!
Thank you for watching and for the feedback!
👍👍👍
Another great video Louis. I'm always learning watching your channel, thanks
Hi
That's great!
Thank you for watching and for your comment!
The lack of space to remove those is unbelievable, nice find and replacing the bad part saved quite a bit of $$$ cheers mate 👍👍👍
It is indeed quite difficult...
Thank you for watching Igor!
👍👍👍
Good video, I learned something. Need to become more familiar with the 2.0 since we started using them in our cars. 👍🏻
That's great...
Thank you for watching and for your comment!

Great video!! I have the same problem on my VW golf Mk6 2.0TDI. changed the N75 solenoid but the same limp mode issue keeps coming on.
Thanks!
Hope you get yours sorted!
👍👍👍
@@LMAutoRepairs Hopefully, Thanks budd
Nice video!

Good job my friend. I don’t have enough experience with turbo engines this helps a lot. Cheers 👍👍
No worries...
Thank you for watching!
Nice post 👌👌
Thanks!

I am not a VW tech but I think your adjustment could go a little more to produce a little more boost so the blue and the green like match more exactly, with some wear and tear in the near future maybe the car might come back with an under boost code? Thank you very much for the great video.
Did not came back yet...😋
But I know what you mean...
Thank you for watching and for your comment!
Hi, smart thinking, not take out turbo,.
Was too much work... lol
Thank you for watching!
Hi sir, great videos as usual from you! Really appreciate them
Was hoping you would help me. I'm trying to figure out what's happening with the A/C on a Holden Commodore. Similar to the Chevrolet. At the relay it has two powers and two grounds if I'm not mistaken and when I jump the switcht the side of the relay, the A/C clutch engages but when you press the switch on the inside it doesn't engage.
Could it be high resistance in the circuit or a failing A/C compressor? Or what else can u check?
Thank you
Hi
I am not sure if got it correctly...
But check the control side... wiring from the switch...if you can force the AC compressor to run, and runs ok, then is going to be something on the control side.
Make sure that there is no other parameters disabling the AC from turning on... like a bad temp sensor etc...
Thank you for watching and for your comment
U should check for gas presence... If the system doesn't have gas it will not turn on.
Thanks for your help guys. Yes there isn't any gas in the system.
I knew the air wouldn't be cold without it but I didn't know that the clutch wouldn't engage without the refrigerant present.
Thanks again guys!
@@konquerorx
That's correct for some systems...
Some systems, will run even with no gas... but some other do not... so you might have one of those...
👍👍👍
Thank you for watching!
Hi, I have 2010 Polo 1.2. I got the headgasket changed and now the engine won't rev past 3000rmp.
And the scan tools tell me fault of "Glow plug control Module" P067000.
No warning lights on Dash 🙁 plz help
I need assistance with the repairs of a 2008 Mini Cooper Clubman S(right-hand drive) this car runs for about 5 seconds then shuts off. Checked
1. Checked fuel pump. Did not hear pump operating when tried to start and no voltage received at the pump. Please advise on next thing to check.
I'm stranded in Bahamas.
Well, if you are stranded in the Bahamas, you are not too bad!... lol
Start by checking fuses, relays etc...
If you apply 12v directly to the pump, does it runs?
Thank you for watching!
to turn off rpm limiter when stationary, deactivate DSC and press clutch pedal
Thanks!
👍👍👍
Do you tighten the nuts on the actuator rod before or after you set the position sensor? Did you count the threads or was it a lucky shot?
Hi
I have avoided to touch the top nut... so I could use is as reference... and worked quite well...😋
Thank you for watching and for your comment!
what's the cost of a new actuator?
Awesome video :). Any help for my problem please. I have a 2.0 touran DSG 2007 tdi pd and same problem. It had a recon turbo because blue smoke and new solenoid valve block unit after a week at the back of engine bay. But every time on motorway going up steeper road it dies and goes to limp mode with restricted power. No boost pipe leaks. Switch off and back on and it is okay for until happens again. This happens more when it engine gets hot. P0299 turbo charge underboost fault. What could it be ? Any help much appreciated:)
If no leaks... check the sensor itself...
Check dpf if fitted an cat... make sure is not blocked preventing the turbo from spooling...
Thank you for watching!
Did you solve your issue mate?
@@shibarmyburnz1978 Fitted new turbo sorted it
THERE IS A REPAIR SET FOR THIS I BELIEVE HOPE U CHECK IT OUT..
Probably... I didn't check...
Thank!
Your lucky you had no error codes after installing the new one. Normally they need setting up properly
😊🤪
👍👍👍
Hi I have a 2013 bmw x6 40d, fault code P4530, with intermittent limp mode, have had all vac pipes smoked checked with no leaks, also changed boost sensor, and also changed throttle body as had it checked and was dropping pressure. Garage dont know what else to do? Can you help..
Hi
You say you checked vaccum lines... what about the actually air intake system?
Check also that the turbo is moving freely, and that there is no air restrictions before and after the turbo...
Thank you for watching and for your comment!
@@LMAutoRepairs hi thanks also is coming up with a LIN BUS Error will that clear this fault also.
@@SKhan-fy7vz
Possibly no...
LIN bus is a communication line...
I also can not apply vacuum, but when I reconnect the hose to N75, I can see the rod of the actuator moving. So why does it do that?
How far is the rod moving?
It might has a small leak, that the engine vacuum manages to move the rod a bit, but makes it difficult to do it by hand... if that makes sense...
What is the issue you are having?
Thank you for watching!
@@LMAutoRepairs while running the test on the N75 from vcds the rod moves about 1.5cm, and does not drop.
I'm getting intermittent P2563 error when applying 3-4 times the brake pedal. While driving I do not see any issues, the car does not enter limp mode.
I also tried disconnecting the hose from the vnt actuator and I plugged the hole of the hose, I pumped the brakes and it does not throw the error code, so I do suspect the the vacuum is lost throughout the vnt actuator.
I must also mention that I have a broken, loose glow plug(nr4) in the engine, but I guess does not have to do with vacuum.
I would say that the glow plug would not influence the vacuum... just as you said...
It looks indeed that you either have a vacuum leak, or poor vacuum from the engine/pump...
Because it happens when you press the brake, it makes sense, applying brake means usage of vacuum, when you press the brake few times in a row, the vacuum drops that low that the turbo actuator fails to maintain its position... throwing the code...
Ideally you would do a smoke test, see if any leaks... also measure the vacuum that the engine/pump is producing...
Hope that helps.
Thank you for watching!
@@LMAutoRepairs thank you, both of your replys make sence, on point and helpful, will do the test tomorrow.

What scanner are you using?? Thankyou

Can you help me please I've got a vw tiguan 2.0 tdi it's coming up low fuel pressure
I've had New injectors new fuel pump new fuel pressure regulator New fuel pressure sensor new intank fuel pump it runs but when you drive it goes into limp mode
I'm not sure what to try next
I have p00af00 with new turbocharger in 1.4 TDI CUS SEAT IBIZA
THE FAULT IS sporadic
THE DEPRESSION IS OK, VALVE N75 IS OK
CAN YOU HELP ME ?
Hi
What about the turbo actuator?
Is the turbo position sensor on the actuator also working?
Thank you for watching!
@@LMAutoRepairs wastegate with position sensor is new !!
I’ve got the same engine same problem low rpm low power code p299
Garage could find the fault wonder if it’s the same thing
As you can see, easy to check...😉
Hope you get it sorted!
Thank you for watching!
Hi tried a vacuum pump unable to build and pressure
So looks like the same thing
Keep hearing about diversion valve I maybe wrong but don’t think this has one
Users this instead
@@marksmith8663
Even if there is a problem with the diverter valve, you need to resolve this first....
it's time to offer cruise control and multifunctional steering for the customer!
Lol
Soon will be a video on that on a trafic 3...
(Already on patreon... )
Thank you for watching and for your comment!
@@LMAutoRepairs You are planning to add cruise control? That would be a great video!! Looking forward to that for sure.
@@keitho77
Hi
Not on this car... this was not mine...
But I was requested to do it on a Renault Trafic 3 from 2014...
The video is already on patreon...
😉
You change the actuator valve and you dont clean the turbo variable geometry?
Not such a good idea, if you want to fix all the problems you need to clean turbo geometry.
And then you have to make basic adjustment of that valve with VCDS like ElsaWin say, top and bottom voltage read by ecu.Cheers.
Robermon YT its the rubber diaphragm inside the actuator that gets broken, why you have to clean the VGT?
No sense to take all apart for the actuator
@@armandonika and why do you think the rubber get broken?
Is quite new car to have this issue, dont you think?
@@patriciomunoz2830 belive me is make sense, in time.
@@MrFluorescentify
Hi
I actually showed the broken membrane inside the actuator...
You might have not watched the whole video...
I have also calibrated the new position sensor... again showed that on the video...
The lever on the turbo was moving freely... as already said by other people, pointless to remove the entire turbo to clean the geometry, when the only problem I could found was the broken membrane on the actuator...
Would probably not be a bad idea to do the cleaning... just don't think would worth the extra costs...
Thank you for watching and for your comment...
Not very good indeed cause you skipping a lot! Thanks anyway
Well... if you need the ABC, then leave it for someone that knows, or practice before touch something like this...
This is for someone with minimum knowledge on this area...

Can you help me please I've got a vw tiguan 2.0 tdi it's coming up low fuel pressure
Hi
PD or CR?
Not sure
It runs fine but when you put your foot down it goes into limp mode
Had new injectors new fuel pressure regulator New fuel pressure sensor new intank fuel pump new high pressure fuel pump
Can it be the fuel control module
