This car had excess smoke, lack of power, codes for P0299 Boost pressure regulation control range not reached and P026A Charge air cooler efficiency below threshold. Vag codes 000665 and 000618. - Авто та транспорт
Good job well worth knowing what to look out for with this issue. Always helpful to know the history of the car in question
thanks
great videos, I am learning a lot in your channel. keep em coming, thank you.
thanks for watching
I had a hole somehow happen on the lower intercooler hose and the ALH smoked like a pig!! I was able to spot it while pulling off the exh manifold to clean it and looked down to inspect it w a flashlight and bingo! The psi that develops in that tube is incredible! Good troubleshooting and fix!
Nice daig that you did on your ALH!
sometimes service centers drill a small hole in the lower intercooler plastic pipe to drain oil build up in the pipe.
Thank you for your time to record and upload this useful vodeo
your Welcome. Thanks for watching. I'll check out your channel.
@@CoolAirVw Much appreciated
@@TheKeenMechanic OOH! BMW stuff. I have a few BMW related videos. One more coming. I'm not a BMW expert but I play one on UA-cam. :0
@@CoolAirVw I am not an expert too, but I am keen to learn. We will never know everything, but as long as we learn new things every day I think we will be doing fine. Will have a look at your other videos when I get a chance. Thank you
Thank you for uploading this!
Hey! I know you! Thanks for watching and commenting.
I liked your video. It was helpful for me .
thanks for watching.
Thank you very useful video
thanks for watching.
What side of intercooler pipe was it? Driver side charge pipe?
Excellent video thank you
Thanks for watching.
This is helpful. Especially when the mechanic pointed out, oil around the hose end @ the intercooler. Boost leak
I’m a little dumb on turbo. What is going thru the left & right side hose, attached to intercooler? Air, oil?
They were replacing the original with an upgraded turbo, & showed me the leak. 👍🏽👍🏽
@@josemsm80 Air but all turbos put out trace amounts of oil mist in the air.
A broken brake booster hose will also cause this code and limp mode. Part of the hose is hard plastic and is susceptible to cracking and/or breaking. Ask me how I know.
I don’t like those clip fitting boost pipes, better with a normal hose and clamp but VAG persist in using them. At the end why does boost run above requested at first, because of the tune?
Keep up the great work 👍👌
Lots of vehicles the boost will overshoot then come under control. Some people run a aftermarket valve to "clip" the overboost off. Mostly on performance cars though.
May i ask you how do you see the VC-Scope at 7:26 recorded ? When you are on Meas. Blocks you first press Log and then Graph, and when you got back you see the records or what ? Can you explain me the steps ?
You simply watch the graph and push the pause button, which is part of the vagcom graphing software. Then after that to save it or manipulate it you hit print screen (or alt print screen) to save it to the clipboard. My video in the following link shows how to do so. ua-cam.com/video/02KJxNnYiZk/v-deo.html
@@CoolAirVw Thank you very much!!! I wish i could come to your service, but unfortunately it's too far from me... i am from Europe/Bulgaria :D :D , and that's why i am trying to deal with my problem alone
@@CoolAirVw Hey again, today i bought a vacuum tool and here's what i found, look at the 1st video while the engine is running and then with shutt off engine, when N75 is ON, the gauge is NOT holding still, is that normal(i checked the the valve that controls the vanes and it works perfect, it hold the vacuum)? But when i connect it to Source Vacuum it is holding still. It only moves after the N75 valve, is the mean the it is faulty?

Das war gut! Danke!
Thanks. 10 hours to edit this one. 3 times I edited the video and it wouldn't save. Finally got it on the 4th try.
Hey man need your help, I have a bmw 5 series twin turbo. I have a P0229 “Turbo Underboost” checked everywhere and saw that the left Intercooler is bent and has a hole on the side of it. Do you think replacing this will fix the issue causing underboost P0299
I think so. Its a logical conclusion. A hole in the side of a intercooler will definitely cause a boost leak.
CoolAirVw Rm Thank you, I will replace it and keep you updated whether it fixes the issue.
@@thewiseguy7100 update? I bet it fixed it, yes?
Bonjour monsieur
Magnifique vidéo
S'il vous plaît
Quelles sont les causes qui empêcheront de voir dans le graphe la pression jaune autrement dit la ligne jaune et merci d'avance
My 2006 hjetta tdi had a hole in intercooler pipe. It blew a hole from inside out and melted the plastic hole size of my pinky finger tip. Lots lost boost. The new pipe is $250-380. But I got a plastic welder soldering iron from harbor freight $18. Melted bubbled up plastic back down to fill hole and cured hard again. Boost came back and then I start working on all others problems like a bad door harness, air bag light, abs lights and selling it soon to get a Toyota or lexus. These tdi cars are nothing but money pits and endless repairs.
Love the improvised repair! Good job finding a fix that saves some money. Used one might have been good too.
Thanks you
You are welcome!
thanks for the video , please i have same car but the problem is not from the hose could it be from the geometry turbo variable ?
Yes. I have a couple other videos on boost problems. Not the exact same car but same logic would apply. Watch those videos for diagnosis process.
5:52 i cannot find those clips for the life of me!!
every clip i find online is shaped different.
dealership. Stop in, look at diagram, order part. Take your vin with you.
@@CoolAirVw whats crazy is i did that yesterday.
They gave me a clip that looks like it goes to the older model tdi's and said thats the part for my car.
Even gave them a vin# in advance.
I cant see the clip working but im all for giving it a try.
Will a leak on the exhaust side if the turbo cause p0299? I'm having serious issues with mine and I can't figure it out
pre turbo yes, post turbo no. It would have to be a large leak though.
How did you get the new green seal on the intercooler the one that's on it is black and they're two different seals I tried for an hour and a half to slide the pipe on with the new green o-ring and was getting nowhere
Magic hands!
Magic hands my ass that's not the right seal that's the seal for the boost pipe that's on the outside and not the cjaa that's on the inside

I thought this was genius and I'm going to do it
@@justenfarnsworth625 Car is still on the road! We do oil changes on it regularly. Maybe next time its in we'll take it apart and look. Thanks for commenting.
This is exactly problem having with a 2006 tdi. Cracked plastic pipe.
Wish you has the video how get that plastic pipe off and installed.
Sorry, the main focus of this channel is diagnosis. Not much time to make how-to's for each part that might be replaced. But if you make a video on how to do it I'll link to it.
It's not too hard get pipe off.
Pull off air filter box, battery box.
Then front lower intercooler rubber hose held on with snap clamps under car near radiator.
Then there's 2 bolts on plasic pipe intercooler pipe.
Then need pull off back mass air flow pipe , near the top turbo is a hidden bolt on a hose clamp.
Then there's coolant lines to the engine and intercooler. Pinch those off with hose clamps or stuff clean rags so don't loose too much.
Then go under car to back engine will see the back hose clamp on intercooler pipe.watch how the spring clamps go on and off. Thats what got me when reattaching to make sure the snap clamps lock back in the little ridges so pipe doesn't pop off.
Then you have to do tetris to move the pipe out all the different things. Took about an hour get off.
Take pictures as you go, and have a buckets or bags of where different bolts , screws go.
If need refill coolant use distilled water if don't have the right coolant. Don not mix coolant types can make salts in the coolant system clogging it.
You'll need t27 and think t25 bits for specialty screws.
@@dylano7242 Nice post!
Hello there, great video.
My 06 has no noticeable leaks, Actuator works it holds pressure, n75 working, when I go to the Measuring block and do a test, the boost pressure reading is normal same with the boost actual, the Charge Pressure drops instantly from 98% to 20% I have no visible engine lights but I do have a underboost code which makes my car not move for a good 2 seconds and blows allot of smoke and suddenly turbo finally kicks in and car goes. My fix for this was a zip tie mod... but car often goes to limp when I go uphill on cold engine. ( please do help) if I take the zip tie it will choke again...
a more permanent fix, instead of the zip tie is to adjust the turbo stop.
CoolAirVw Rm is that an easy adjustment? Thank you for the reply
CoolAirVw Rm Please do explain how to adjust it and what the process is
@@Itsarmando416 No. Its not so easy.
@@Itsarmando416 Seems the same info that you found to lead you to zip tie it would show you how to adjust it. Basically you just want the stop to prevent the vanes from going full closed. It tends to stick in the full closed position due to wear and lever angle. I've fixed dozens. most of which someone (dealer and other shops)had allready recommended replacing the turbo.
Nice job man but how did you know that there is a boost leak causing the problem and not the n75?
Initial diagnosis had zero boost and smoke. Zero boost plus massive smoke equals major boost leak. Output test shows quickly whether n75 works or not. I never did a output test on this car but I've shown it in some other videos and it would be the same on this car.
Thank you
@@CoolAirVw what if it makes full boost say 18psi then drops suddenly and holds back to 5ish psi then pulls hard to 18 again and vice Versa during full throttle ? 🤔
i have a 2006 VW jetta Tdi and we have the code p0299 come up. low power and tons of black smoke when driving. we have replaced the intercooler pipe once about two years ago. I took it to a friend who put it up on a lift and when he reved it looking for leaks he saw massive ammount of black smoke coming off the EGR cooler valve. he reccomended replacing the EGR cooler. would that cause the p0299 code? i would just love to bring it to your shop if you were in Utah. Do you know of any shops here in Utah that you would reccomend? your youtube is by far the best i have found for Vw tdi
that code plus black smoke probably equals boost leak.
Push the tool away always not pull towards always good vid tho
smashed my self in the head once!
Where did you connect smoke tester to car? Was it the intake? I have just made a smoke tester to find boost leak
I believe best spot is right at maf sensor.
I f-ing hate VW !!! I have a lack of power and no check engine light on!! I flashed firmware on computer flashed software on it and it still has the same issue!! I can edit hex code to remove torque limiter but that is when I start having problems with clutch dmf etc: I do alot of highway driving and clutch has no slip it just grabs instantly :( OMG I hate this car so much
I'm sorry your having troubles.
