I just found the cause of the p0299 code that keeps popping up on my wife’s car. It’s the corrugated tube that goes from the intake manifold to the top of the turbo. There is a check valve in the end of the tube just before it connects to the turbo. The check valve gets stuck open once in a while and causes the intermittent code. I just put a new hose in. 80 dollars for the hose and 10 minutes later. No more codes

was it also slugging on power?

First thing you should do is remove that heat shield and check the waste gate arm. There’s a little valve that tends to stick that keeps the waste gate from closing or sealing tight inside the turbo. If ignored that’s when these turbos crack and then need to be replaced. You can check by unbolting from block and try and move it up and down if it’s gummy or sticks that valve is the problem. Also you can remove turbo and check the seal inside. If it leaks then the fan will not turn and that gives the underboost P0299 code

I'm getting p0299 code. How do I diagnose if irs turbo going out

Drive it with a code reader plugged in it will take some highway driving to open all the sensors 8 total. You can watch them clear with green lights one at a time. If check engine light stays off after all sensors have green light problem solved. In most cases. Engine light could come back on after a couple more miles driving. After about 5 more miles no light your good to go. Go to have inspected will now pass emissions.

pcv valve issue? the 1.4T has well-documented issues with a poorly designed PCV valve; could failure of that valve be responsible for the oil finding its way to the air intake? i've also heard that the PCV valve is responsible for the rough idle. not a mechanic here just someone with a P0299 in my 14 sonic rs who's been obsessively googling possible diagnoses lol

Underboost could be indicative of a failing turbo. I just went through replacing the entire turbo and pcv system. The oil feed line on the turbo especially is known to fail. Mine had long failed and everything else failed miserably afterwards. Its easy to get to and replace you need a special torx bit but its worth getting the set if you plan on working on this thing. The oil return line is also known to fail but that is a pain in the ass to get to.

The trick is to to replace the intake manifold and the valve cover at the same time to fix the pcv problem. As they work together. If you only replace one of the two,the problem will be back sooner than later . You must replace both to fix rough idle, code0299, under boost is a direct problem from the pcv when it reaches around 100,000kms. I'm at 300,000 +kms and still going strong.trust me I know .

Did you ever really pinpoint the exact issue. Like you did something and didn't have the issue again? I'm hearing the only real fix for the whole system is a bypass kit for pcv. I must say this car sucks but I kinda like it. I like to tinker. Played with old Hondas when I was in my twenties then drove Camry for a couple of decades and nothing ever goes wrong. It's not my only car so I have that luxury to play with certain things and replace. I've replaced so many things on the Coolant system most of which is brittle plastic. I'm also having the oil in the Turbo intake. I'm pretty sure my Pcv flap in Intake is gone but so black I cannot see. Also probably need a new pcv tube from intake to turbo because I can blow air both ways and supposed to be a check valve in there. I'm also always getting high negative fuel trim. Replaced the evap purge valve but same thing. It's getting extra fuel somewhere causing the negative trim. I think I may have a leaky injector. I've had all the codes one time or another but seem to be a hiccup every now and then, then once cleared don't show up again or very seldom. If you like fixing things that break all the time, get a Cruze. You want to just change fluids and have a car just run, get a Camry. Barring any Catostrophic engine or transmission failure, will try to get 200k + out of the Cruze.... At 130k now but optimistic.

The Doorman Intake Manifold off of Amazon positively fixed the issue, as the check valve on the stock intake had popped. That being said, the engine continued to run rough at idle until the coolant system purged itself, a process that took a few weeks and about 400 miles of driving. I guess in the process of draining and refilling the coolant and air blockage gets in the system. I had to replace the gas cap because the spring in the original gas cap went soft and caused an evap leak code. Right now I have to be sure to run 93 octane chevron gas for best results. Occasionally I’ll still throw a check engine light and it’s will go away as quickly as it comes. There coolant system plumbing you described is also very bad, with the water outlet corroding, the return line breaking at the t junction, and the coolant reservoir leaking as well. I really can’t imagine how GM allowed these cars to roll off the assembly line with this type of quality control issues.

@@BS-fz8td Negative on both. The check valve is actually located IN the intake manifold. Its an integrated design. You can go two routes, either replace the intake manifold with the AC Delco or factory original, or you can utilize the Fix Kit from Cruzekits.com. Either route will get the car serviceable. You check for the presence of the check valve by peering into the port on top of the intake manifold and seeing if you can visually identify the red little nub protruding out. You’ll need a flashlight to determine this. If you can’t see it, it’s either popped, coated in oil to make visual identification difficult, or recessed in with a different style intake manifold to make it impossible to see the nub. Therefore, you should utilize a cheap borescope off of Amazon to 100% identify the presence of the check valve. Another issue is that PCV soot can get on the check valve itself, causing a check engine light to trip, though in my case a dirty check valve caused a MAF code, and not a P0299 code.
