2010 Jetta Tdi Turbo boost leak P0299 

thanks for watching

thanks

Hey! I know you! Thanks for watching and commenting.

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.

thanks for watching.

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 RU-vid. :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

thanks for watching.

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.

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.

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.

You are welcome!

Love the improvised repair! Good job finding a fix that saves some money. Used one might have been good too.

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.

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-02KJxNnYiZk.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?

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.

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?

smashed my self in the head once!

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

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ac8d3NcHQ_w.html 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.

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

@@Livevideos416 No. Its not so easy.

@@Livevideos416 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.

pre turbo yes, post turbo no. It would have to be a large leak though.

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!

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 ? 🤔

that code plus black smoke probably equals boost leak.

I believe best spot is right at maf sensor.

I'm sorry your having troubles.
