Today we are continuing the Tuesday episodes where we look at a failed VW or Audi part. This is like the podcast and Shop Shots piled into one. The response to last weeks show about failed VW 2.0t water pumps was awesome. I am thrilled that you guys like these shows. So be sure to remember that Tuesdays are failed part analysis days.

We look closer at the 2.0t intake manifold

How it fails
Faults that may show intake manifold failure
Drive-ability issues with a failed intake manifold
How it fails
Intake manifold runner sticks
Intake manifold solenoid fails
Connecting rod for runner breaks
Sensor fails
Ways to test the intake manifold

  • TY so much for posting this video. I was pulling my hair out trying to figure out a misfire on Cyl 4. I replaced the usual suspects, ignition coil and spark plug, with no effect. After watching your video I checked and discovered the arm had popped out. Popping it back in fixed the misfire. I guess I will be replacing the entire manifold with the new version eventually, but for now I'm back on the road.😃

    Mr Humble: I cannot thank you enough for your video. I have had three manifolds on my Volkswagen CC, and the third has failed. I have to drive for my job-I need my car!!, I have no time due to my two small kids, and I have other car expenses due to being hit by an uninsured driver. I loather the prospect of paying out for a new manifold. I just snapped back in the little are you described and my car is running great!!! No fast slow idle, but now a smooth idle. I cant thank you enough!!!

    FYI... the solenoid and the arm are parts you can buy individually at places like Rock Auto so the intake manifold can be repaired at a lower cost now.
  • @sweeneyryan987
    Even though I don't own a VW, I still watch all your videos and I find them fascinating. Really quality information, and I think a lot of things can carry over to other makes. Just wish you worked at a nissan dealership! :)

    Failed part. Both my fuel pump 1800.00 and my water pump 3000.00 failed 15,000 miles apart. Intake fail was what I put in shop for. Mechanic said just a vacuum hose was off, but my water pump was leaking, needs r&r. $3000. later I pick up, drive 10 miles and engine light comes on. Return to shop, they are putting on new intake today. Then I looked you up! Thank you, Man! A real answer in about 3 minutes.

    Just as I was thinking "would be nice to see a DIY removal video" I hear you say there's a link in the description! Guess where I'm going now!? Great series, looking forward to next week's video.
  • @brianhayes6752
    Thanks for the great info. The car was flagging the 2015 and 2187 codes. After watching this video I found the input shaft had backed out. I put a little pressure on it and moved the vacuum shaft and it popped right back in. Now it has a very smooth idle.

    Great to see these videos, great to know what is going on within the car, and why. Thank you so much, I can diagnose issues and save money so it can go to buying diapers and save some money, unfortunately I do not have so much money I can bring the shop in to fix all the time. appreciated!!!
  • @Vis-Light
    Me epc and check engine light turned on and the rpms would rise so I having a drive ability issue at a stoplight..this video prevented me form buying an intake manifold and found out the part that’s attached to the actuator was loose thank you so much for this video you just gained a sub
  • Thanks for the video! What performance impact will it have on your vehicle and can you continue driving with these fails?
  • Cheers mate, a very clear concise video, just what I was looking for. Very helpful, thanks.
  • @XXGunzNClipzXx
    I remember hooking up the scanner and getting a code for the intake flap, thankfully it had a test plan and life is easier :D
  • Humble Mechanic, thank you for sharing your expertise... I viewed you video on removing the manifold. What experience with my CC one day was I started my car and it stalled which never happened, with a flashing CE light. Then I stayed it again and it had a rough idle, drove successfully with no light. Started in the morning with a CE light... throwing all codes 2015 and misfires, etc. checked out your video on replacing the manifold. CE Light is still one. No rough idle, smooth ride, maybe slight less power but nothing significant... do I need to erase CE? Thank you sir.
  • @ftschembari254
    Thank you for the information! I have an '09 Passat 2.0T TSI, it has 121k miles so of course it is 1k miles over the extended warranty that VW issued out for the intake manifold.
  • @andymendez7710
    thanks for the video. I found it while troubleshooting P2014 fault on my 2015 Audi A3 (8V) (manifold runner position sensor). Car is running fine, but I would guess I need to get new manifold to clear this fault, although I may try to replace the sensor first.
  • @Joebus100
    I really like all your videos. Thank you so much for putting them together. This one saved me a bunch of time and money as the little flap rotator thingy was popped out on mine making the car nearly undriveable. Brought to a VW mechanic and $400 dollars later nothing changed. I've managed to pop it back in but when I put my thumb over the end it's still pulling a small vacuum on my thumb. I'm guessing this isn't normal and the manifold should be replaced?
  • My intake didn't fail but when it came time to do another valve cleaning I decided to change it since the car now has 160K miles. The actuator and flapper were all nice and tight. Boy were those valves and injectors gunked up ugly. I'm not surprised it was running so poorly after seeing that. Thanks for the video..
  • @mischief007
    Have been watching some of your videos and subscribed.  I work at a VW dealership but not as a tech.  I enjoy your honesty and nice to see that you are a car guy :).

    I had a newer tiguan at work a while ago. Brought it in had misfires across all cylinders,random miss,boost code,and some lean conditions and drivability complaint. The peice popped out like you said I sent customer to the dealer for warrenty extension once I had diagnosed. Cool video thanks. suscribed
