Gotta check out part 2 because there's 2 pressure sensors & a few other things that can cause that code.

@@wandameadows5736 will check it asap. Thanks for the heads up. Cause I’m keeping this baby to a million miles lol.

I'm getting same code in my 2011 Jetta 2.5L. I thought I should replace the sensor, but sounds like I should clean it and change the diaphragm before replacing sensor correct?

@@davisgrier5162 Yes I would recommend doing both the sensor and the diaphragm. I replaced just my sensor and had my code come back. Were you able to resolve your issue?

My 13 Passat just had this pop up at 146,000 I'll fix it when I get done with truck driver orientation 🤙🏿

How do the intake bolts go lose if no one worked on the intake? Are these bolts become lose by time with the engine vibrations or expansion and contraction?

@@surefire07 maybe the valve cover gasket?

I just got a 09 jetta it makes a weird sound kinda like an old caravan I got the car for 2000 cash I found a picture of a map sensor with the price of roughly 100 Any advice???

Indeed he did, well explained, no bullshit in between like others do!

Best thing I have done is reset the transmission control... I don't remember exactly how to do that without youtubing but if you get in your car (without turning it on) you'll notice that pressing all the way down the accelerator will click a button. Google after that (because every VW is different) but its something like pressing all the way down on that and clicking the button and then turning the car on (without starting the engine) and holding it for around 30 seconds. And its a reset for the transmission control. Often times resolves awkward transmission shifts.

Did this fix the issue? I would get random pulls thinking it was the trans fluid as well. I just got the check engine light.

@@mauriciopereira7705 Honestly there was nothing wrong with the transmission, it was the MAP sensor getting all oily (which is ridiculous), and my throttle body was extremely dirty/sticky. I feel like the feeling of a 'bad transmission' was coming from the dirty/sticky throttle body. Then, it so happens to turn out the MAP was oily as well. 😕 Does that help?

Looks like you posted this a while ago so I hope you figured it out already but if you haven't... There is no maf sensor on the 2012 2.5L engine. Only a maP sensor (I capitalized the P on purpose!!!) - Manifold absolute pressure sensor. There is no mass airflow sensor. The MAP senor is like $30 so it's a cheap replacement

Fuel system cleaners are not designed to perform that job. They are marketed as a fuel injector and or valve cleaner. The issue is that oil doesn't atomize very well and simply running the car will not get all the oil out. The shape of the plastic intake plenum adds to the chances of oil staying trapped at the bottom, where the MAP sensor resides.

Having the same issue with my 2012 Passat 2.5. Replaced my MAP sensor, cleared the code using a scanner, code came back. Will be replacing the diaphragm and cleaning the MAP sensor to maybe fix the issue. Were you able fix your issue?

@@JoeSmoeDoeLow did you ever resolve the problem?

@@eluna58 yes I solved it. I replaced the map sensor and the diaphragm and then cleared the code using my scanner. I put 15,000 miles on the car and no code has returned.

@@JoeSmoeDoeLow ok, thank I'm going to first try and just change the diaphragm and clean the sensor hopefully that works. Thanks for the reply

I have been driving my Jetta for 3 years with this code appearing about 2 times per month. I deal with it so often that I have a code reader in the passenger seat and I have developed the ability to clear the code while driving! I saw this post at random a few weeks ago. I bought a PCV valve from Rock Auto for a few bucks (less than the cost of the code scanner) and now my problem is solved!!! THANK YOU SOOOOO MUCH!!!!!

You're the man! I just replaced my diaphragm because of this video, Thanks for making this!

Inan Ismailov probably just a different set up for emissions. Regulations change per region not to mention car so it probably something like that.

huggyjd Try to get as much as you can. Normal air flow will clear up any thats left.

Technically, I would say yes. I think it would be rather difficult though. Removal of the components is neither difficult or damaging (no gaskets needed).

An intake leak beyond the mass air flow could cause it. Generally in my experience, the code is more of a product of the air leak caused by the tear in the diaphragm. I'm sure that oil doesn't help the sensor though.

PISTOL PETE the reference to the light being persistant was that, before preforming the fix, it would take a few days to return if I would simply clear the light without doing any work. If you have the code, check the map sensor or intake for oil. If there is any, then you have a pcv torn. Since the fix, the code and tested and passed without issue.

Actually I ended up doing nothing and the code disappeared after a car wash. I wonder what will happen if I try to get a diagnosis test now

PISTOL PETE Thats how mine was at first. The code didn't go away because of the car wash. Like I said in the video, it came and went for me at first. Eventually it stayed on constantly. The code is still in there. 3 key cycles in a row without an issue and the light goes away. The stored code take much longer to clear from the computer.

Hi! I have the same problem and I read about the VW TSB 2034012 but I don't how can I require that upgrade... could you please give a little bit more information about how did you order that upgrade?

You should never neglect car repair, especially check engine light issues. Try to get it looked at and repaired as soon as possible. Second, there are many reasons why your car might have this specific code. This video shows a repair of the most common cause of this code.

Here is a tip for you, check your intake manifold bolts, they may be loose. A loose intake manifold can contribute to a code p0106. Upon doing this, vlean inside the intake manifold, clean out your throttle body, clean out your hoses & check your intake manifold bolts. Throttle body - torx 30 Intake manifold bolts - either a 6mm hex or a torx 40 Clean with throttle/intake cleaner For map sensor, clean with map sensor cleaner..could be bought at walmart. Vlear out your p0206 with an obII reader. Good luck and hope it helps you.

Did you replace the PCV diaphragm?

Mohamad sy just one map sensor like in the video.

Are you sure? Then what is the purpose of the other one that is under the oil cap? It's the same exact sensor. I checked my car and it does have the one you replaced at the same location, but didn't get chance to swipe them. I'm confused now!

Mohamad sy The MAP sensor is simply a pressure sensor. Car makers use the same sensors for multiple things. The MAP sensor is where I described in the video. Any thing else is probably just a pressure sensor for another system. make sure to watch the "whole" video. I did NOT replace the MAP sensor. I replaced the PCV valve and CLEANED the sensor.

Alright thank you! I will do everything you did and tell you how it went. I searched a lot but no one has any post or video about where the sensor is located so I got the wrong one. Thank you again for the videos !

how did it go?

I feel your pain. Having the correct scanner equipment is a must as the years go by. I understand that it is cost prohibitive for most to have supportive scanner hardware let alone the software to accompany it. But it's getting to be impossible to perform work on the vehicles otherwise.

I’m dealing with the code coming back after all the repairs have been made same as you. The car runs great but I do notice the car doesn’t do the cold start with warm up cycle anymore. It just goes straight to normal idle. I’m now getting a too rich at idle error and not sure what to check for next along with the P0106 code that keeps reappearing.

@@Suprasian ricksfreeautorepairadvice.com/vw-p0106/

Hey Eugene, what was the verdict on your problem with your vehicle? I’m having the same problem…

@@Hudsonnblackk On the engine block on the left hand side (by the cooling fluid reservoire, there are two plastic plugs. I'm not sure what is the purpose but I think due to the blowned PCV diaphragm, it create a vacuum inside the engine and sucked in one of those plugs. Anyway, I removed the crankcase cover and I found the plug inside, resting by one of the valve lifters. I could re-install it but I bought new aftermarket ones and installed it. I did apply some RTV sealant on it, just in case. So, the main culpit was the PCV diaphragm, second, I found oil in the throttle intake, (there is a sensor there too), removed the throttle body, cleaned it up, and third issue was the plastic plug on the engine left-hand side. The plug was very dificult to troubleshoot as the engine was running soo rough , I thought there was piston broken or worst. Since then, she runs perfect. All these were induced by the PCV diaphragm which I never replaced it in more than 10 years. Some people are replacing them every few years. They are cheap and easy to replace.

Did you get this issue resolved?

Van Coll no the code keeps coming back every few days after I clear it

The 3078 and the 106 could very much be related. They both can be triggered by intake air leaks possibly caused by a ripped pcv diaphragm. As some other posts have suggested, VW has a campaign out for the P0106 code which involves reprogramming the ECU. I don't think that's gonna fix your issues since you have more then just the 106 code. Secondly, the 322 code is for the engine speed sensor and is most likely intermittently faulting. I say that because the engine speed sensor (aka crank sensor) will prevent the vehicle from starting if bad and will stop the engine immediately if it goes bad while running.

Replaced the MAP sensor and diaphragm, but no luck. The chamber covered by the diaphragm had a thin brown film on it that I cleaned out. The Speed sensor is next. I think this will do it.

i have the same problem did you figure out what's causing that?

@@_DaRobot same problem

I really thought I was the only one haha… was it just the map sensor?

@@_DaRobotdid you figure it out?

There's 2 sensors & several other things that can cause that code. VW made an upgraded Secondary Air Injection Pipe for VW/AUDI part# 07K198125. I have a 2012 VW Jetta 2.5L I bought used & luckily it had already had the upgraded pipe installed. I actually bought the pipe & went to install to realize this. The new pipe has a new sensor "VOLKSWAGEN 07K906051". This pipe & sensor is located on top of the motor just right of the block. The sensor this guy showed in this video is located on the Manifold. It's important to understand how the pvc system functions. The diaphragm separates' the oil & air & when it breaks it causes oil to drain down into the manifold & get burnt & cause carbon buildup on the throttle body. So if the diaphragm was bad it's good idea to replace the 2 sensors that can get contaminated or clean them at least & then see if the throttle body has carbon build up & clean if necessary & then behind then behind the throttle body you can shine a light down into the manifold & look for oil & clean it. There was a bulletin released by VW because the p0106 code was showing up in a lot of shops. Here's the bulletin copied & pasted below. I've been dealing with this code on & off for 2 years. It comes & goes & doesn't cause any major driving issues but so I'm going to pull the manifold cover off & make sure everything is clean before adding new sensor's. Those diaphragm's seem to tear easy & while I love my Jetta this is a stupid design. VW P0106 Diagnose and fix VW P0106 Shops are reporting a high incidence of VW P0106 trouble codes. And VW has issued a service bulletin 24-18-02 to address a VW P0106 or P3078 trouble code on the vehicles listed below. P0106 is Manifold Abs. Pressure or Bar. Pressure Range/Performance and P3078 is Throttle Valve Control Module Air Flow at idle too Low. Vehicles affected by VW service bulletin 24-18-02 2008-2009 Rabbit 2.5L (CBTA, CBUA) l 2008-2014 Jetta, Jetta SportWagen 2.5L (CBTA, CBUA) l 2010-2014 Golf 2.5L (CBTA, CBUA) l 2008-2014 Beetle, Beetle Convertible 2.5L (CBTA, CBUA) l 2012-2014 Passat 2.5L (CBTA, CBUA) l Cause of VW P0106 The VW P0106 code is usually caused VW P0106 cause is carbon buildup in throttle bodyby carbon buildup on the throttle body but the carbon buildup can be caused by a faulty PCV valve that allows excess oil to pool in the intake manifold which then damages the MAP sensor. Do NOT make the rookie mistake of automatically replacing the MAP sensor because this may be a simple case of carbon buildup inside the throttle body. Diagnose root cause of VW P0106 Remove the air intake duct from the air filter. Manually open the throttle plate and check for carbon buildup Next, shine a light into the intake manifold and check for standing oil. If you see standing oil, you’ve got a problem with the positive crankcase ventilation system-see below. If there’s no standing oil, remove the throttle body from the intake (you’ll have to buy a new throttle body gasket) and clean the carbon buildup using a rag and spray throttle body cleaner. DO NOT SPRAY the throttle body cleaner directly onto the throttle plate shaft. The spray can seep into the electronics and damage the throttle body. Always use a rag. Reinstall the cleaned throttle body. Clear the code and test drive. If you find oil in the intake The crankcase ventilation system is designed to remove blowby gasses from the crankcase and route them back into the intake to burn with the air/fuel mixture. The ventilation system on these engines is designed to separate out any oil vapors from the blowby gasses. When the oil separation system fails, oil doesn’t get separated from the blowby and it settles at the bottom of the intake. The MAP sensor is located at a low spot and oil can enter the sensor, causing it to fail. Remove the vacuum line from the MAP sensor and check for the presence of oil. If you find oil, replace the MAP sensor. But you’re not done yet. Perform the following test on the ventilation system With the engine OFF, disconnect the hose running from the engine to the intake manifold Blow into the hose. You should notice air resistance. If so, then the check valve is operating properly. If there’s no air resistance, the check valve has failed. Replace the PCV valve Next, with the engine running, disconnect the hose from the valve cover and plug it. If the idle quality improves, replace the PCV valve. Remove the dipstick while the engine is running. If the idle quality improves, replace the PCV valve Remove the oil filler cap from the valve cover with the engine running Hold a piece of cardboard over the opening. The engine should suck the paper onto the opening. perly. If the engine fails the ventilation test, replace the PCV valve. VW may or may not sell the valve as a separate part. In some cases you may have to replace the entire valve cover to fix the problem. After replacing the PCV valve Make sure you clean the oil from the intake. Then replace the MAP sensor.

@@wandameadows5736 Thank you for providing the service bulletin. I own a 2009 VW Jetta 2.5. I replaced only the pcv valve using the doorman part last year, May 2022. As of today, i've been getting the p0106 code. I've been cleaning the hoses, intake manifold, throttle body & map sensor for the last couple of months which has been resulting in oil residue. I just purchased a new pcv valve, by doorman. Going to replace it again, clean hoses, clean the intake manifold, clean the throttle body and map sensor Sunday, April 16, 2023. Hopefully this works. If not, i am just going to replace the whole valve cover. Maybe the whole valve cover with a new pcv valve needs to be replaced in the first place as stated in your bulletin. I will keep those who interested posted.

@@alfredbernal8603 If your still having the P0106 code I found another bulletin on a software update that's supposed to reset the barometric pressure parameters. It claims the original parameters were to sensitive. I've had the code come on & go away on its own but haven't taken it anywhere to see if its had a software update because beside the mil coming on once a month there's no problems. I've hooked my scan tool up & read the live data before clearing the code hoping I could catch it when it happens but no luck. I read on a VW form that the pvc design was bad on these engines.

Clean it first. If it still acts up, replace it.

Rav Ocean Probably, if you remove the sensor and find oil, then yes.

Skyhook Studios so I ordered the Doorman and replaced it today. I cleaned the sensor that I put new last time, I cleaned everything I was able to. The plastic on the old Doorman was the same color as yours, but it didn't have any cracks tho. I cleared the check engine light, drove today all day and I got the same code again. I'm really getting disappointed. What should I do?

Maybe you didn't clean up all the oil in the intake?

Skyhook Studios I tried to reach as deep as I could to clean it. I couldn't clean it fully though because it was unreachable. Any suggestions for that?

Rav Ocean if you pull the map sensor out again, does it have oil on it again? If it does then you might not have installed the PCV valve properly. are you getting the p0106 code again?

Sergio Valerio 2008, 2009 and 2010 VWs are having the ECM reflashed for the P0106 because of a computer reading error. The video shows oil on the MAP sensor, as many others have found, but never do I say replace it. If you have this code and you have oil on the sensor, then the PCV breather is faulty.

That’s what I got. My transmission is shifting hard and I got the wrench at the gear indicator on the dash. Comes and goes. Car runs fine when the wrench is not there. Check for codes and P0106 is what I got

@@randomghost4385 check your intake manifold, if it's dirty/oily, clean it, then replace your map sensor, check if it have oil on it. if it does it probably means your pcv diaphragm is damaged and leaking oil into the air intake. replace it. many videos on youtube for this for the vw 2.5

@@kumbackquatsta Thank you. I will check and clean before I start throwing money at things

@@randomghost4385 good luck. all my weird shifting has come from those three parts, usually the pcv diaphragm leaking causing oil to get down to the map sensor via the intake/manifold. all parts can be replaced with hand tools at home.

@@randomghost4385 heads up on the hose clamp too. best to get a hose clamp wrench, although can do it with other tools, it's just tedious

You might be able to get away with that if the PCV is torn. The only difference between intermittent and permanent is the failure rates. In order to set a light the code has to fail 2 times in a row. Intermittent means that it has passed atleast once since setting the light.

PIPELINE CONSTRUCTION KZfaq yes, lights been off for almost a year.

Thank you.. and i subscribe

It's not necessary. Just make sure the key is off and out.

It's tucked down in there pretty good. It's unlikely to get properly cleaned without removal.

@@SkyhookStudios I've never really done anything besides headlights, air filters or fuses but I really don't want to pay a shop.

Other then residual oil, the PCV is the only culprit. If these cars had turbos, then I would say turbo seals.

thanks, maybe i'll purchase another PCV valve diapragm and see it stops the leaking.

@@SkyhookStudios I've replaced the PCV cover twice now, haven't seen a tear on the previous one. Oil still getting onto the MAP sensor. I've clean the sensor, the intake manifold and the PCV hose the best that I could. Do you think there is another leak elsewhere or am I destined to replace the Engine Valve Cover at this point?

Tim Tan did you ever get this resolved? I’m having the same issue

Tim Tan did you resolve the issue? Same problem

Get an oil catch can

Did you ever get this issue resolved? Please let me know, I am having the same problem

Van Coll yes it was my valve cover

Yes, it worth trying to clean the sensor first rather then just replacing it.

Yeah ima just clean the sensor first.

Adam NK it's possible that the map is bad. If there was enough oil to mess it up, I would say yes.

I should update this in case anyone comes across a problem similar to mine. So I had a check engine light with 2 related codes: P0106 and P0106 (pending). 1) Followed the video here and replaced the PCV diaphragm and cleaned the intake where the MAP sensor was. MIL light came back. 2) Replaced the MAP sensor since maybe it was ruined by the amount of oil in the intake. MIL light still came back. 3) Took it in to the dealership to have it checked out for me and turned out to be a malfunctioning throttle body. They wanted $1100 to fix, I bought the part for $130 online and replaced it myself instead. Driven > 600 miles on the car since then and the MIL light has not came back. Thank you for the video, I have learned so much more about what's under my hood following this video taking things apart. Much is appreciated and best of luck.

Adam NK What was the part that you replaced for 130? The throttle body?

Yeah, I bought a used TB online. I believe the tag that it came with same it was from a 2009 model. Keeps the Check Engine Light away so I wont complain.
