Golf V R32 :: Exhaust Leak - DSG Rattle?
Mar 31, 2012
I did some searching and found someone with the same dsg rattle chatter noise I am getting from my R (check link below)
My R has 102,000 miles, runs excellent but the dsg makes a noise mostly when I am in gear stopped with my foot on the brake. While I was under the car checking out the chatter noise I noticed a faint exhaust leak somewhere in the headers near the flex pipe. I want to fix it and I plan to put on a cat back exhaust very soon but I really don't want to spend the money on a set of headers.

I recently purchased this truck and have towed a couple of times with it. It has 98,000 miles and I do not know if the automatic transmission fluid has been changed. Should I have it flushed or drop the pan and change it? I have a lift so doing the change is no problem, although it might be worth it to pay a transmission shop to do it.
Also, I hear what appears to be like a heat shield rattle or something that sounds kinda like an exhaust leak during loaded acceleration. What to look for to locate the noise? One last question, the air bag light is on sometimes then off sometimes. Any known air bag light issues? I love the truck, hate the gas mileage!

I just got my R last Monday and have noticed a weird rattle coming from the exhaust. It only happens when I am driving. I can rev the engine when parked and the car sounds great. The rattle seems to happen when the car shifts and seems to happen less often if I've been driving for a little while. I did take it to VW they put it on a lift and checked everything underneath. I was told it might just go away but if not to come back and they will further check it out. What it might be?

OK, my stock exhaust would rattle when I shifted UP with the DSG, seems to be a fairly common thing. I got the EJ exhaust and it STILL does it on occasion, not as bad. Is there a loose heat shield or something? If I rev the car slowly while driving (not standing still) and get it to red line there is no metallic rattle. If I rev it fast and shift, it rattles

Ever since I got my 3" TB installed I've noticed it rattles on the rear beam. I have tried wrapping the beam with exhaust wrap but it lasts for few days. What could I do to fix it?

So I recently lower my car and my 3" exhaust started a constant rattle when I'm in the car. When I get out it stops. Been lowered for a week or so now and today was the first time that happened. I've read up and seen its pretty common when we go lower. Also some ways to possibly fix it.

Everytime I run my revs past 4 and shift, I can hear a steel rattle right at the shift. It's stock exhaust btw, no mods...

I'm just curious, I have milltek catback and lately, i feel like I can hear a very small exhaust leak somewhere under the car. I could be way wrong because I get super paranoid once I hear an odd noise, so anyway would a small leak light up the CEL?

Yesterday the car was fine going to work and most of the way home. It was raining pretty hard and I went through a large puddle then right after I started to hear a pretty loud noise. It sounded like it was coming from the middle of the car, more so in between the main seats and was vibrating my seat a little bit. It only happened on mediumish acceleration, during low acceleration it wasn't there at all. Also the car still felt fine. Then when I got off main road I was on a street that wasn't super wet cause of all the trees, the sound stopped.
Here is a link to the sound, you might have to turn up the volume because it is a little low. You can hear it best around 14 sec: [URL].....
So today I jacked it up to see if I could see anything and I found oil all around the haldex stuff. Here are some pics I took of the leak. There is also a bright yellow spot you can see through a hole. Not sure what that means. The haldex service was done, maybe 5-10k miles ago, I'd have to look it up to figure out exact time. In one of the pics you might notice black silicone around one of the plugs, this was because when I did get it serviced for the first time, someone before stripped the bolt so the mechanic put that around it to hold it in. It still looks like it is on there pretty well so I don't think that is the issue.
This isn't a big deal but I noticed this plastic part isn't bolted down, I really don't think the noise would be from this but posted just in case.

Have to do a replacement and if so.. is removed the intake the only way to get at those stubs on the ex manifolds.
I thought it was the flex-pipe.. but after listening to the sound and getting an engine code for b1 s1 the leak has to be before the o2 senor for it to pop a code..
It sounds like a standard header leak from backing out bolts or a faulty gasket leak..

I've noticed that potentially my heat shield or whatever guard that is 1 step toward the front of the car from where the inlet pipe connects to the exhaust system may be the reason for my rattle at 2k and 3k rpms. i think its a heat shield but I am not sure. the thing is it seems properly mounted, nothing is cracked/broken/or loose. But when I do try and wiggle it it does make a slight creaking noise that sounds similar to the rattle I get. So I could foresee this as being my issue.
But, is there anyway to fix this rattle w/out just taking off the part? i figure its there for a reason and it looks like its held on in 2 places. But they're not nuts they almost look like spot welds or something. 1 on each side. What to do?
Something to get you all in here:

Recently bought a MKV R32. Already had a magnaflow cbe, k&n panel filter, and some emissions stuff taken out from under the hood. not sure if it has been flashed, waiting to get a vagcom. think it is pretty stock other than that. My problem is about 2 weeks after I got it, I started to notice an exhaust leak or vacuum leak or both at higher RPMs, like above 3 or 4k it starts. The exhaust has a nice deep rumble in normal driving but when the leak noises start that is all you hear, the exhaust note disappears completely. I have tightened the clamps on the cbe and still does it. Not sure what to look for.

I feel as though my APR turboback has an exhaust leak.
There is a loud hissing noise that overwhelms the exhaust, turbo and engine noise. What it is. Sounds like a loud hissing when then turbo begins to kick it. Not normal, and it slowly has gotten worse and more noticeable.
I have a feeling its the downpipe, but I can't check it myself. When i give it gas and the hood is open (at a standstill obviously), the engine compartment smells like exhaust fumes.
Could be playing mind games with myself. What do you all think? Any way to surely test and see? I am taking it to dealership on Tuesday to double check.

So i have an exhaust leak that melted the wires on o2 sensor bank 1 sensor one. This put o2 sensor bank 1 sensor 2 into lean mode and i found this out last week. Made the appointment. Was gonna run some test and replace the o2s if needed. But this morning i go to leave for work and my coolant light comes on 50 feet up the road. I pull over look at my coolant. There was about an inch of coolant left in the tank. Roll back down the street turn the car off and leave it. Im thinking i blew my head gasket running lean. When i get back from work the coolants in the same spot so i jack the car up to see if i can find the coolant leak and i dont see anything. Drop the car back down and the coolant levels back to normal so im alittle lost on whats going on here.
Also after work before coolant level returned to normal i reved it up it blew a little white smoke then black. Nothing really dark. It was quite faint. And also the coolant in the tank would bubble from the back under rev when it was low. Nothing at idle. When coolant level returned. I didn't see any smoke at all and i was unable to check coolant.

I have a leak between the turbo and the exhaust manifold. The golden clamp (c-clamp? v-clamp?) broke, and now there is a gap between the two. The dealership doesnt cover it under powertrain warranty (my car has passed regular warranty) but worst of all they do not sell the clamp on its own.
I posted a link to a picture below, it isn't my turbo.

Brief back story, a year ago my timing belt went and had to replace the cylinder head and all associated parts. No problems since then, until now. Recently the check engine has come on, and got the code for an exhaust leak. Can't remember the exact code number, but the leak wasn't causing a lean condition or causing the engine to act weird so I left it until I had to time to find the leak. On the way home today I noticed an exhaust leak that got increasingly worse to the point where at a stop light I'd go to accelerate and it would pull away very sluggishly. Got home, opened the hood and tracked down the exhaust leak to somewhere around the manifold/downpipe/turbo area. I took off my cover and noticed what could be a bolt missing, and upon further inspection a bolt that may be coming loose.
Here's what I'm referring to:
- Missing bolt?
- Loose bolt missing bolt?
- Loose bolt?

I'm working on a 2003 Jetta GLI 1.8t (MT and 140,000m if it matters). The CEL has been on for a couple of weeks because of an exhaust leak throwing a catalyst efficiency code. After I make this post I'm going to run down to the advance auto I used to work at & see if I can borrow the scanner to see if there's anything new, but as of right now I don't know. I'll update the thread if I find anything.
The car started yesterday AM perfectly fine. Started again when I left work around noon. No problems with the start, idle, acceleration.. it's all good.
3 hours later I tried to start it to go pick up my kid from school but it just cranked without firing and would not start. I took care of business with the kiddo and then started trying to pin down the problem.
1. Opened the door & listened for the fuel pump to prime.. No sound.
2. Noticed the dome light is on.
3. Checked ALL of the fuses on the side of the dash.. All are fine. Turned key to listen for secondary prime.. no sound.
4. Bought Fuel pump relay & replaced.. no change.
5. Cursed.. a lot
6. Bought fuel pump.. replaced.. no change.
7. Cursed a lot more.. and cried a little too.
8. Noticed the fuel pump was now priming with the key being turned, but still not when I open the door.. Dash indicates the known CEL, but now I notice that the EPC light is on too (this could be from all the fruitless cranking drawing down the battery charge)
9. Figured I'd throw in a new crank angle sensor cuz of the EPC.. no change.
10. Shot starting fluid down the intake.. didn't hit a lick.
I feel like I'm at a dead end.. It's acting like a bad ignition control module, but there's no such thing on a vw 1.8t.

Finally got the car started after over a year of acquiring parts and labor. Cylinder 5&6 had misfires due to faulty injector harnesses. That issue has resolved. But I am getting a pretty distinct exhaust leak noise coming from the manifold area and i cannot figure out where it is coming from. We smoke tested it and still can't find the leak.
Things we checked:
-Head to manifold (all nuts tight)
-Manifold to turbo (all nuts tight)
-Turbo to downpipe (2 vbands both tight)
-Wastegate (2bolt manifold to adapter tight and vband adapter to wastgate tight)
-(2) O2 sensor plugs on the maniold (tight)
-All turbo hardware (tight)
-manifold and downpipe have no cracks

I installed the non-resonated exhaust, but I noticed that some air/water condensation is coming out of the small pipe that join the cat and non resonated part of the exhaust.
I double checked the position of the small part and is very deep inside the other tubes, plus I checked the clamps too.

So I did the seafoam trick and I came to the conculsion that my exhaust leak is coming from either the manifold or the flex pipe. There was no smoke coming from under the car only a mist of smoking coming up from the back of the engine, probably by the manifold or the flex pipe. I do not see any visible cracking per say. I have attached a picture of the end of the flex pipe and it almost looks like someone may have tried to seal it before? I don't know if that is normal or not as seen in the picture.

I tore it apart and there was no gasket or donut ring in the flange. Is there supposed to be a gasket or donut ring? I can feel the leak with my hand. I have retightened & it still "tick-ticks" real bad.
