Hi
Right... what a mess..
Let me explain... this car had a few parts replaced, some new, or reconditioned shall we say, still, the car still suffering the same problems...
After a bit of diagnosing, found the issue, the problem was, that was the "new" part was at fault...
And that, well, that I was not allows to touch!...
UPDATE AND FOLLOW UP:
The car ended up coming back... 3 months later and not fixed!!!
Ended up, in order to save some money, to do something I so many times criticize... So, I know I have opened myself to some backlash... all of that on the last video on this car...
Here are the videos for it...
And the Audi comes back... let's fix it this time...

A massive thanks to Alex for confirming my suspicions...

Well done and glad you are paid for your time. Couple of thoughts, the original garage have tried to fix the car as cheap as possible. The garage obviously put the wrong parts that don't work, especially with modern electronics. Sometimes you have say no to jobs, and in this case give a written report as supporting evidence. The garage must know who you are and if they see this video, want to fix it properly for the customer!
Don't think they will know me, I am just a car enthusiastic, that's all...
There is a lot of "I know it all" mechanics around here, tha will not listen to someone like me...
But stay tuned...
Thank you for watching and for your comment!
Had a similar problem. Was turbo actuator. ,…..expensive , buy cheaper than new turbo. Good luck to u. ❤
What u did here is something that I always wanted to know. Man u the one the Dr Order. Thank u God bless. Good job
I had the issue where it kept going to limp mode because the dpf wasn't doing what it should be.
Changed turbo actuator, programmed it, gave it a carbon clean and then cleared codes, has been running sweet for the last 3 years now
👍
Thank you for sharing this with us
☺️
👍👍👍
This was so frustrating to find. Not sure how to charge lost time on this.. Great video
Tell me about it...😓
Thank you for watching and for your comment!
👍👍👍
Thank you for another great video!!!
Thank you for watching!
👍👍👍
Why oh why oh why dont people learn to just bring the car to you first. You alwaysdo the right checks and get the issues found
☺️
Stay tuned...😉
👍👍👍
Thats a good catch.
☺️
Thanks!
👍👍👍
That's the problem people should replace like for like would save a lot of time and messing
But as usual you found the problem
Very well done
☺️
Indeed!...
👍👍👍
Absolutely love ur diag vidz. Wondering if it be possible to post you a small PCB to get quote to fix?? It searched online for months to find correct part to solder on to fix it but had no luck and tbh I'm guessing thanks in advance sir
I have a high end autel, sometimes i get stuck as it cant do all cars wouldnt reset a dpf after i cleaned it on a grand vitara last week what second scanner do you have im thinking of buying a launch to hopefully cover a wider range. Thanks
Happy to help if i can Luis....😊
☺️
Thanks Alex!
👍👍👍
Awesome

Good video!
But for new VW cars better to use Odis for diagnose.
And I think (99%sure) that firmware in ECU have switch to change to another sensor. But is really hard to find, without Damos fast imposible.
Thanks!
Agree...
👍👍👍
But lets say you change it and the next time the turbo ge5s changed and the correct turbo is ordered think about the mess that would cause the poor tecnician that tries to repair it. I think there will be a few turbos fitted before anyone will figure it out!
Also true...
I had a similar situation, where a DTC was deleted from the ecu, the car was going into limp mode with no codes... as soon as I flashed an ORI software the problem was immediately highlighted by the trouble code...
👍👍👍
I had the same problem on an old skoda octavia with push and pull actuator difference
☺️
👍👍👍
Brill video and thanks for sharing. Can I ask what size air suspension line coming from the compressor to the struts or each wheel and the size off the threaded push fit that goes to the front legs . Any info would be great . For an Audi A6 2.7 allroad diesel
Never worked on one... but usually those are 6mm or 8mm... but I might be wrong...
👍👍👍
Thanks Luis excellent,, 👌 i like the Autel machine,, Don't have one yet working on it
☺️
👍👍👍
Thanks Luis I need u here by me with ur Autel machine,,my Honda Jazz,,key light flashing non starting,,,🤔
I have videos on that if I recall correctly... just search the channel...
Thanks Luis ,had a new key made,,not that,, checked computer box not that , , can it be fuse box,,no fuses blown,, relays all ,, good,,can it be ,, relearning,,?? Thanks Luis,,,🙏
Luis I had a Honda frv,,last year also key light flashing,,,it was faulty speed sensor,, checked all systems, and found that, 🤔
Get a license and start your own workshop, Luis.
Cant you switch the pins over ? For the turbo would have been interesting in the name of science lololol love your vids man really informative
Not really... but stay tuned...😉
🎉🎉🎉
☺️
👍👍👍
, Yea some scanners dont show fuel pressure and sensor 3 egt
I use the vagcom on vw and audi etc
☺️
👍👍👍
Another posable problem could be the injectors with the engine being replaced are they the original ones swapped over to the replacement engine or did the engine come with injectors and were they coded in and balanced
Could be... buy no...
👍👍👍
I'm betting the replacement engine came with the wrong turbo and got fitted and then the people who changed the turbo just switched it out like for like as you would without knowing.
A very plausible possibly...
I can't however confirm or deny...
I have no info regarding that...
☺️
👍👍👍
@@LMAutoRepairs a good tuner should be able to change the values to make it work
👍👍👍
Does the actuator even move physically? Because if it's not, it may be a common power/ground problem between the actuator and the temperature sensor, as those look to be close together and may be on the same wiring loom.
It's not stuck vanes because the turbo has been changed.
It does move, as you see on the live data...
👍👍👍
My first thoughts with a glow plug light is tandem pump. Just started watching though. Also that coolant tank is overfilled jeez. Interesting that the turbo is different. The part number is the same just the revision of it looks differently. I'm surprised it would affect that much. I don't know how the electronic actuators work, but could the vacuum lines be reversed causing the swapped voltages?
This is not PD engine and do not have Tandem pump!
Can't really reverse the vacuum...
There is only one vacuum line to the actuator, if there is vacuum it works...
👍👍👍👍
@@moldovanandrei7008 no prob:)
@@LMAutoRepairs yeah no worries. I was thinking when I watched the video that there is a vacuum to turbo actuator but couldn't remember if there was another. Seems strange it being an actuator but also very possible too. Nothing surprises with these makes
@RoadRunnerMeep
Stay tuned...😉
Hi Alex great video where do you recommend getting ETKA from like the version you had
I wonder what is wrong with the exhaust temp sensor? Seems like open/short wire because of 999degree pid
Possibly...
Stay tuned...😉
👍👍👍
hi enjoyed ur video on audi a1 1.6 tdi about voltage wrong way round,would know what part no to buy to fix as iam not as good at cars like yourself and iam in glasgow to far to bring car to u,i bought car like this and i kid u not its been in every garage i know and cant fix it ur help b great,
If you know exactly what you need, get an original actuator... unfortunately I don't know the part number..
Or get in touch with some turbo specialists in the area, and explain the situation...
👍👍👍
@@LMAutoRepairs thanks great advice
Hello! I have error on turbo electronic actuator on a Seat Altea XL 1.6Tdi CAYC engine. I was informed that I need to change the actuator and the new one has to be programmed. Also the turbine has to be dismounted and checked. Could somebody let me know what are the steps of the Electronic Actuator replacement? Thank you in advance.
What is wrong with the actual one?
The actuator is a vacuum actuator with a position sensor...
Just remove one and install the new one...
There a procedure with the correct scan tool to program/reset the new actuator...
👍👍👍

Thanks!
👍👍👍
That cover has cay g lol i literally tried to change a cay a to a cayw the thermostat hole in block is diffrent size 4 days ago
☺️
Many times they look the same, but are not...
👍👍👍
what kind of vcds vci ur using ? and is it limited to only 10 VIN's N
Clone... not limited...
👍👍👍
Louis I need your contact info need some help Jaguar XF not starting have rear BCM fault
Couldn't the correct actuator have been modified to fit that turbo. ?
The correct actuator extends the rod rather than retract...
Could probably be possible, with cut and welding... not sure...
But stay tuned...😉
Just flip over the wiring so the signal will be right
Someone already suggested that...
Unfortunately that alone wouldn't work...
The sensor is not a conventional variable resistor...
But stay tuned...😉
👍👍👍
DO you have a hack /way into ETKA - without paying the subscription ?? - Thanks for the video's thya are top class & very usefull to home mechanics
It is an old offline version... but still good for older models...
👍👍👍
@@LMAutoRepairs Ok - thanks for the reply - info used to be free - now its at a price = problem for home mechanics !
Indeed...

Hi
What about if te bottom voltage is 1.3 volts.
I bought new actuator and I can’t set it bellow 1.25V similar as old one and fault code is coming back. I’m trading adaptation but it’s not work
Was the new sensor genuine or aftermarket?
👍👍👍
…aftermarket.
…now I checked genuine (old) working from about 1.3V up to 4.7v and aftermarket 1.16-4.6
Is the turbo lever fully travel to both ends, is it not jamming?
Yes, it doesn't jam. Even when the actuator is removed the lowest voltage is 1.2 and when I unplug actuator completely module showing actual 1.19V
I am guessing you have already tried the learning of the turbo... right?
39:22 Aaaaaah...no more comments 😊
😅☺️
👍👍👍
I mostly refusing to fix the car after someone else...
😊
I should do the same a lot of times... but I always try try to help... and a challenge is always welcome!😋
You need life adaptation Turbo actuator vcds won't help
Does the live adaptations change the way the ecu reads the voltage, by reversing the read?
👍👍👍
@@LMAutoRepairs it will change the way of ECU read .....
I know it adapts the max and min value, as different as not all sensors and turbos will give the exact same voltage read when on max or min position...
But changing completely what the ecu is expecting to see is news to me...
I thought that might be possible with a flash, as already mentioned, with only an adaptation don't know...
Just swap the 2 wires 5v and ground for the potentiometer and LEAVE ecm wiper wire which goes to the ECM alone where it is
FIXED!!!!
It will INVERT the turbo actuator potentiometer logic.
It will switch the ranging of output voltage 5V to 0V output to be change 0V to 5V!!!!!!!!!!!!!!!!!!!
😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡 so simple
FGS
FIXED FOR £0
Is not that simple... but stay tuned...
👍👍👍
@@LMAutoRepairsit is that simple you mentioned the vacuum is moving the actuator in the correct direction (push pull actuator) but the feedback signal the actuator’s potentiometer voltage is reading 4V instead of 1V, and consequently would read 2V for example when it should be 3V etc etc etc so the voltage is moving in the opposite direction……..
So for the 5V potentiometer swapping he power and ground reverses the way wiper voltage
Swap the output wires of the potentiometer for the actuator’s sensor!!!!
It is not that simple... the internals are not a conventional potentiometer... so, humble your comments and consider that not always things are that simple...
Your assumptions are wrong...
As I said, stay tuned... there is more to it, and you will see how mistaken you are...
👍
Did not cheat but it looks like shi tt y mapped vehicle
Don't think it was...

Careful with the camera, you are filming your hands waving across the lens. We can't see through your fingers, so it is very distracting. I know people on youtube have started doing this and it has spread so everyone thinks they need to on videos - but it looks rubbish.
If you are filming something close up and pointing out a part that's fine - if you are standing looking at a car, talking about it and then pointing at it, there is no need to as we know what you are pointing the camera at!
Many youtube people do things for a joke and see how long it takes for others to copy their style.
There was a youtuber that suddenly started using this huge old fashioned 1940s microphone and put it in front of the camera so it was difficult to see his face. Within days, other videos appeared and people had bought replica mics and put them so it blocked their face.
It was a hoax as the person had a clip-on mic.
Counter offer….
Its his video and he can do what he wants and if you dont like it, dont watch?
