- How to fix P0299 Code: Turbo / Supercharger Underboost Condition
The boost is the amount of positive pressure that is being created by the turbocharger.
When the pressure is low, an underboost condition will exist, which the computer (ECM/PCM) will receive through sensors and send out a P0299 code.
The computer calculates the parameters with data from sensors such as the mass airflow sensor, ambient air temperature, and manifold absolute pressure sensor
The computer will consider variations but there is a threshold of pressure needed or the computer will send out a P0299 code.
Possible Causes of a P0299 Code
Intake Air Restriction (Dirty Air Filter)
Bad Waste Gate
Bad Hose Connections
Air intake leak
Faulty sensor (BARO/MAP/Boost Pressure Sensor)
Faulty intercooler

I have a 2017 Buick Encore. I got a P0299 code last September. I tried all the checks recommended by various mechanics. I came to the conclusion it has a bad turbo - at less than 40,000 miles. I recently received a letter from GM that if the vehicle has a bad turbo before 10 years or 120,000 miles, GM will replace it. It's been at the dealer 3 weeks now. They have determined it's a bad turbo. They're really dragging their feet, but I hope they will replace it. Obviously, GM has lost a lawsuit.
Update: I just got my car back, after 5 weeks at the dealership. They replaced the turbo and related parts. Cost: $0.00
This is literally what I am hoping for our 2018 Encore that is throwing this P0299 code. ONLY because it will be covered then and not something else to pay for. Thanks for the additional bit of hope for Monday's appointment 🤞🏼
@@ashleygriffin7481 I hope it works out for you.
Where can I find that GM letter? I have tve same come on 2016 Buick with 117000 miles 😅
@@simoncesABCthey should send you that letter in the mail but considering your 3k miles away from voiding the turbo warranty I'd set up an appointment at your local dealer. They most likely gonna make you pay diagnostics fee between $100-$200. Call and tell them your mechanic said your turbo are bad but he told you they are still under manufacturer warranty...
Informative and easy to grasp.. thanks for making this video.. I appreciate it.
Great video...I have that code on my polo 6 GTI 2011
Damn I wish all videos were this informative… awesome job brotha
well explained crystal clear, excellent , well done . time to get my hands dirty. thanks very much
Thank you for an excellent presentation, well made and helped lots - thank you 😊
Can low boost pull oil from the corrugated PCV hose to the intak manifold and ON the oil light?
Fantastic, thanks a lot, THUMBS UP. God Bless.
Great video
good video, are you saying 1 code could be because of 20 different things
I just had this code after fixing my car for timing chain cover leak. The code came together with P227900 Intake Air System Leak. I can hear the air leaking (loud hissing noise) when paddling above 2.4k rpm. This is not common. Need to further checking with the mechanic tomorrow. The mechanic suspect have issue with the N75 air hose vent. Need to further diagnose. I am driving 2013 Jetta. Thanks for your tutorial.
I had a similar issue but it ended up being a turbo clamp for mine. Replaced it myself and my turbo has been boosting normally
If you pos is an Audi, look at your coolant pump and see if the vacuum line is full of coolant.
Just got this code on my wifes 2018 equinox. I got the P0299 and P0132
Permanent
O2 Sensor Circuit High Voltage Bank 1 Sensor 1
Air filter was pretty dirty, would the P0299 code cause the P0132 code? The car only has 38k miles.
Well
Done
I have a 2022 Chevy Trax that has a po299 code coming on I buy the most expensive oil that I can but then I also bought some oil additive for the turbo pretty brand new turbo it's not making any sounds I don't really seem to be having lots of power I don't know what I could be I do feel like I'm having problems with the wastegate controller that would be fairly hard to push an open and close by hand right
Hey thanks for the info. I am searching for the "wastegate sensor" location 2020 Buick encore gx any ideas?
Getting maf sensors replace just hope its a simple issues
Tenho uma Pajero Dakar diesel 2013 - 3.2 - anulei a EGR começou a aparecer esse erro P0299, ativei à EGR e o erro não apareceu mais
Iv got a 2019 Chevy cruise with the p0299 underboost how can I find what to fix with out buying a new turbo .it only reduces power when taking off from stop .an runs fine Untill I stop again it acts like it is sluggish also
is the problem solved
@@bahadrunal7343did anyone figure it out?
My women’s 2017 Honda Civic EXT is having this issue no boost at all
What if the engine light turned off but I used scanner and it still came up and that’s the only code
I see oil on my intercooler hose is this a sign on a leak on my hose?
No its common if there are little drops
I am receiving error code P0299 in my 2020 1.6 Diesel Opel Insignia vehicle. I can't solve it. Turbo was overhauled, Particle filter was overhauled. Turbo hose changed. But the problem did not go away? Maf sensor and egr valve changed. Please can you help me
Simple terms I have ti replace the turbo

Hey, I have this code in combination with a P0101 code..what action should I take ? Is this a sensor problem when combined with the P0101
They likely are separate issues, but I would clean the MAF sensor, clear the codes, and see if they come back.
You ever figure it out?
Hello Sir,
Thanks for the video. How long can I ride with that code before getting it repaired? All the lights in my dash are on. It's running fine. I can't understand how I got a brake job 3 weeks ago then 2 weeks later all the lights in the dash of my 2022 Honda Accord are on. I have 162k miles on it and have taken good care. Now this trouble. They're telling me it's 2400 to repair it at the dealer. In face all the codes state "see dealer "
Same thing happened to me after brake job it’s frustrating. Any updates?
I have a 2005 T1N 2500 van.. I got this P0299 code. I couldn’t find a leak and also I hear the leak only after I drive for an hour or 2 and then all of a sudden I hear it leak and my turbo don’t kick in. I have to turn on and off my engine and then it works fine for 30 to 40 miles and same thing repeats.. any idea what might be the issue?
is the problem solved?
Any estimate on how much it will cost to fix it?
2015 f150 around 2k to fix it.
2100 on my 2017 cruze
I had this error on my Jetta sw, I replaced the boost pressure valve, but I’m still getting the same code. what should be the next thing to look into?
I had the same problem before .Check the bottom hose that is going to the intercooler that's usually gets sucked or loose
2014 kia sportage underboost same code . Sometimes turbo is functioning sometimes not
Bro I get that problem too on my Chevy trax 2018 1.4 lit 4cylinder, it will come on for a little bit then turn off for a while, so I assumed it might be sensor related or something with the waste gate
Very helpful, thank you. Is it ok to drive with this code if your vehicle is running well?
Did you ever get an answer bc mine is doing this an I gotta work .. which is far.. 30 miles one way
@@nae1300I’ve been running mine for about 3 months and I do good delivery, I just clear the code but I’m hoping to fix it this week
Man me too n I sleep in this mfer 😢
@@-2k5 I had to change the turbo out
@Beast-rz9cd
What was the issue specifically? Bad blades? Scratch up housing? Hard to believe the entire turbo needs to be replaced unless you're getting one pulled over your eyes by the mechanic
Idk why I’m getting this code.. my car when I press the gas it don’t respond correctly it’s not getting enough power not sure what it could be
is the problem solved?
