Default TDI is hissing and blowing air

My TDI (2006 Jetta TDI) is making a hissing sound and leaking air. Trying to figure out what I need to replace/fix. Below is a picture of the area/part that is leaking air. It hisses really loud especially when I press on the gas. It hisses a little when idling, but not nearly as bad. The part is kind of behind the engine (towards the rear)

Any help would be greatly appreciated

You’re real near the EGR pipe. Could it be that? If so, you could consider a EGR delete / cooler delete. Will require a tune to remove the check engine but no biggies. Also - maybe a video would be better than pic. Check all of the vacuum lines also the turbo and air intake.

yup. I wonder if its this thing right here.... had mine fail, bought a new EGR pipe. had that one fail very shortly after, so I put in a home made EGR delete kit, wasnt strong enough and that just failed on me last week after 100,000 or so miles. when it gets really bad, your cabin will also stink like diesel fumes... gross and extremely harmful for your health. posting a video would help a ton





IF, its your lower EGR tube, continue reading.

you can see in these pics that my EGR tube has lost that little flex, accordion piece. twice that happened. I bet yours is starting to fail too, starts with a small hole, next thing ya know shes gone and you got NO boost anymore as no gasses are spooling the turbo.


the fix is very simple. note how thin my home made delete piece is?? DO NOT make yours as thin as I did. triple that thickness at least, the real kits are nearly 7mm or 1/4" thick as they are exposed to extreme heat and do not get sandwiched between the tubing like that.

you may also need to make 2 more of those plates for the upper EGR piping also. very easy stuff. a beginner can do it IMO. some bolts are a tad tricky to get at, but overall super easy.

someone please correct me if im wrong.

it looks like everything under there is covered in soot? could that also be hinting towards the EGR tube having a hole?

After a bit more research, I do believe you are right. Some part of the EGR is leaking. If it is just an EGR pipe that is leaking, could I put some sort of high temp gasket seal or QuikSteel on it to seal the hole. Or would that mess it up even more?

Yeah, no.
You need another pipe, or delete it.
Definitely soot all over and you want to light up the back of the engine and take pictures of it to see where it's not covered in soot.
Make sure there's nothing crazy going on with the exhaust otherwise spewing soot as well. It's possible to have a boost leak and exhaust leak. That really does look like the EGR system is done though

No silicone. I believe those gasses going through the egt are over 1000f and possibly a little pressurized. The delete is incredibly easy

Not that high unless you're running really hard, generally between 300 and 800

ohh ok. good to know.. I was just going off the EGT gauge on my 5.9L cummins which was pre turbo and would hit 1300-1800F depending how hard you were on er. either way, shes hot in there!! hot enough to melt a hole in my little 1/16th inch piece of tin siding! silicone is not the fix for this.


I personally wouldnt recommend another pipe. I went that route and within 6 months was back at square 1, hours from home, and $150 pipe ruined again. theyre famous for it. theyre junk, just delete it and never worry again.


there is VERY minimal downsides to deleting your EGR, and TONS of positives. one of the biggest downside is it wont warm up quite as quick in the winter... might take an extra 30 seconds, no big deal at all. I believe its mainly there to clean up your exhaust gasses a tiny bit more.. its an environmental, emissions thing but comes with a LOT of headaches and isnt worth it in the end. get rid of er!


little extra reading in here if ya want. general consensus is to delete the EGR, it does more harm than good: http://forums.tdiclub.com/showthread.php?t=495449

Thanks for all the very helpful info. I really want to do the EGR delete, but worried it won't pass emissions. Where would I take it to have the the CEL tuned out? If I wanted to just replace the whole EGR Cooler, how hard is that? Dealership quoted me $1100 which is a lot.

Also, here is a video. Excuse my yelling in the video.

ok maybe its not the tube, but rather that little EGR cooler valve... just like this guys:

you were right, I was wrong. sorry!

some good info here regarding the cooler valve: http://forums.tdiclub.com/showthread.php?t=283909


not too sure what the emissions test all consists of, if they can actually tell its deleted just by your cars fumes or not, but as far as the block off plates go and a visual... if you sneak some plates (thicker than mine) in between your EGR pipe flange and the header, no one would ever know

A very common problem on the BRM engines. The shaft for the the EGR cooler butterfly valve is leaking. Mine showed signs of exhaust leaking at 55K miles and at 185K miles It would hiss and was effecting drivabiity.
Frank Irving (Franko6) has a permanent fix that will not effect emission testing results.

Thank you for the referral, Ol'Rattler. I appreciate it.

I have a problem with this 'block off plate' fix. You may have blocked off the exhaust gasses from the manifold to EGR pipe, but you have done nothing to stop the boost leak coming from the other way. You will still leak boost through both the EGR to manifold pipe and the leaking seal from on the EGR cooler's butterfly valve, which is the main culprit. We know that a major portion of the boost leak will still happen, which is degrading your engine performance. BTW: The circles in Fouillard's pictures, showing the areas of exhaust gas leaks are 1/2 right. The Bellow on the manifold pipe are broken, but the other circle, showing the vacuum diaphragm, is incorrect. The exhaust gasses are leaking on the butterfly valve, directly under the exhaust pipe. So, Fouillard, I'm thinking you are wrong.

I am also going to guess that the reason the exhaust to EGR pipe broke is because not all the screws connecting the EGR cooler to the back of the block are tight. If the EGR cooler is shaking, that is the usual reason the pipe's bellows on one side or the other, fail.

We can get a replacement exhaust pipe and make a repair to the EGR cooler and that fixes the problem and restores the operation of the engine. The reason we make the EGR cooler operate; it heats the antifreeze, helping your engine to warm up more efficiently. We think that is a good idea in Denver, as it can get very cold. You'll need the EGR's ability to heat the engine's coolant.

We keep a steady supply of our repaired EGR coolers in stock, with the proper installation parts. We also buy back your broken EGR cooler, if it is a repairable core.

Questions? Feel free to call.
