| Post subject: | Kid with gremlin p0299 again… |
Sorry for asking so much recently, I don’t want to do this too. But the day after I thought I fixed my turbo issues by replacing a broken vac tube the p0299 came back >:( albeit this time my car was actually very much driveable and smoked more than normal but a LOT less than before that was until I encountered my first steep hill in which the CRD was slower than a yugo up hill. I replaced the rest of my vac lines today and all seemed fine anyways. I’m bringing it to a more affordable Cummins shop to get the vac modulator and vac regulator tested. Is this the next thing I should do? update on the parts I’ve dumped Sasquatch turbo Mishimoto hoses eBay egr delete Silicone vac lines Oem turbo install kit New 5v plugs(if they matter) |

I would check that one of your mishimotos hasn't popped off. Since you were doing some work in that area, I mean. Once my intercooler hose popped off the engine inlet on the driver side. At a glance it looked like it was on, but it was just resting against the mouth of the aluminum inlet tube and any boost pressure at all would lift it away and lose all boost. So yea, black smoke and no power. |

Update: I did the vaccum bypass test every says to do and the car drove the same. Made a hissing sound from the vaccum modulator when it was unplugged |

If you performed the bypass test correctly, there should be no ports left unconnected on the modulator valve to make any noise unless there is something wrong with the valve. If the modulator valve is making a hissing sound with both hoses connected, then I would suspect the modulator valve is bad.

I did exactly as you pictured, I just replaced the vacuum modulator and filter with a used one from offer up, there was a guy parting out an engine somewhat nearby… same p0299 after putting it on… at least it was only $30. I’m on my own again cause the shop don’t want to touch my car. Last resort is to bring it to the shop I got my electrical work done but thatd cost near $1000 to figure it out according to the advisor |

I think I fixed my issue… I will right a post in 3 days if it stays that way I think others may make the same mistake I did. Long story there are 2 short vac tubes that are easily accessible and are two different sizes on each side. Basically I put the larger size on both and I guess vacuum was leaking out of the connecting points. Will have pictures if this is the issue. Fixed by putting the old ones back on |

Fixed by putting the old ones back on Yes, you have got to definitely use the correct size vacuum hose, there are two different sizes used on this engine. 3mm & 5mm, and the big one 3/8" from the engine over to the vacuum brake booster where the small supply line connects going to the turbo controller and HVAC inside the dash. |

Update: I still get a pending p0299 car drives pretty much normal with no smoke though. I’m gonna replace the vaccum modulator, solenoid and the big rectangle thing that doesn’t usually break. Found a couple guys on eBay selling the whole assmbly with all of them including the filter for $30 if that doesn’t work I’m going to bring it to the guy in kenewick. Thanks for the help again guys. |

I also am getting a P0299 code with intermittent P0110 & P0105 codes. I pulled the CAC hoses and will replace. I checked the turbo wheel and it spins freely with little movement. I checked the turbo vane actuator and it barely moves 1/4 inch. I will perform the bypass test tomorrow. I am going replace the MAP sensor also. Jerryfluffy - let me know if you solve your issue. |

I have not fixed my issue yet but your issue may be the Mercedes sensor that’s located next to the maf sensor. I left mine unplugged once and got the same codes. |

I have the same problem has you. I suspect it is an electrical thing because sometimes the boost cure by itself...and then after a while it return with low boost and p0299. |
