TDI BEW Vacuum Leak Fix & Explanation

Experienced weak brakes and no turbo boost, so I went down the path of diagnosing a presumed vacuum leak. The leak ended up being the nipple on the vacuum pump weakening over time and leaking. A gob a JB weld saves the day.

Thank you Mate, you just saved my weekend, I was just ready to hit the road when the power brakes failed, I have exactly the same jetta, including the supports for the turbo hose, and it failed exactly the same way, THANK YOU

Thx! I'm going to go threw this whole vacuum system, again! I do have intermittent boost leak. I will find it.

Dude i was diagnosed with a hard brake & failed, but I've got the exact same issue it's lose & can't tell if air is escaping I'm gonna give this a try as it could be a cheap fix ✌️☘️🇮🇪

Same problem here on a 2005 2.0 TDI Passat. Thanks for posting. Not sure if JB weld is flexible enough for this repair. There are some flexible epoxies on the market now or perhaps high temperature RTV (silicon seal). I’m going to sleep on that question.

Great video, I'm having the same problems, ABS kicks in randomly, and car slows poorly every now and then, turbo actuator stopped working too, thankyou, will update when i do it 👍

Any update I’m having same problem and I see the same bit is loose on my Skoda (1.9tdi same engines )

@@jordanstanley4623 I'm not sure about the ABS randomly kicking in, but if that vacuum connection is loose at the tandem pump you'll likely have vacuum leaks. My JB weld attempt with the pump still on the car eventually failed. Fortunately I had to remove the pump when doing a camshaft swap. With the pump off the car you have much better access to properly goop on the JB weld and get a strong weld.

Great video! I have a 04 BEW 1.9 Jetta wagon and I’ve replaced the turbo actuator along with some lines and still have same issue. I know my nipple is loose so maybe I’ll give that jb weld a go. I also did the doggie collar as well. I even used 6 inch heat shrink to go over my intake hoses because those connection style wears and makes them leak air too.

I ended up having to goop on the jb weld with the tandem pump off the car (was doing a camshaft change so it worked out nicely). It was too hard to get a god strong seal on the bottom of the footing with on the car.

Hi, can silicone sealant work on this? Same used for oil sump/pan etc.

@jeffreyprice9315 2 жыл бұрын

Which JBWeld line of products did u use to seal it?

@Stewbaru 8 ай бұрын

Would that cause fuel to come out of that area? I have a fuel leak around that area and cant figure it out

colleague, you have oil on the vacuum path, which I don't think has anything to look for there

could that wiggle of the vacum fail brake booster to brake(work correctly)?

@jmvoltrino 3 жыл бұрын

Yes. If you have a vacuum leak it will severely degrade the performance of the brake booster, depending on the severity of the vacuum leak. Sometimes the leak is minor and it’s able to “store” enough vacuum in the vacuum reservoir in between brake applications, so the booster will only fail to work sometimes.

@@jmvoltrino i was cleaning out my intake manifold, and on reinstallation of the manifold and egr cooler, i accidentally broke the arm of the intake manifold vacuum actuator. it’s located on the passenger side of the engine, shaped like a little circular plunger with an arm (pointing towards the front of the car) going to a pivoting bracket on the intake manifold. it’s just below your “doggie collar fix” and is made of plastic. when i reinstalled the intake system, i took it for a drive and under high boost, high load, up until VGT actuation i get a very loud squeal and a “flat spot” in my power curve. i have no clue what creates this, and i’m not sure if that broken arm on that actuator could create that noise. i have a new one on the way but it’s not gonna be here for a week or so and i’m kind of scared to drive my car because this noise did not happen before and i don’t want to damage anything further. any thoughts? i thought it could be that intake manifold vacuum actuator arm being broken but i don’t know what to do anymore. thanks in advance
