Golf IV / Jetta IV :: Exhaust Burbles Way More Than It Used To / No Smooth Decelerating
Nov 6, 2014
Today I was driving on the freeway and a noticed my cars exhaust burbles way more than it used to, like it used to do it at around 1500 rpm when I am decelerating or between shifts, now it always does it when I decelerate like there is no smooth decelerating sound I used to have its just all crackle and burble, I do have an exhaust leak but I've had it since I did my down pipe and it was fine before, I've ordered an oem one and ill slap it on when im doing my fmic install, i did replace all coilpacks yesterday so maybe I did it wrong if its even possible to do that wrong. And also my windshield has so many nicks in it like it looks like a lot of dirt on the windshield, it looks like it'll wipe off but it doesn't there's no cracks just tiny dings all over the windshield.

My car to me... seems like it's down on power. I don't know why but it sure doesn't feel like it used to. I don't know if it's brain related or vehicle related but I do know the car "burbles" at idle and by that i mean it feels like it's jerking around and sputtering but fine when I take off. I also hear the dv more than I did before, where as before it was much quieter now it's louder and can hear it with the windows up. To make matters worse, and I am in no way condoning any of it - my car could barely out pull a 4th gen Jetta 1.8T that's stock.

VW GTI 1.8T 5 speed.
So I've blown the differential on my transmission, it's been blown for a little while. I have basically no transmission fluid at all.
Question: Why is the car still driving normally?
Some time ago I was getting a transmission fluid flush and change, my gear shifter was a bit stiff before the change and after changing the fluid it became smoother.
According to my mechanic that would be the result of changing the fluid.
Question: So then why is my gear shifter completely smooth without any transmission fluid at all and a blown differential?
Question: what will happen if I leave it like this? I'm assuming it will eventually seize up?

I noticed a month ago that my transmission didn't feel as smooth whenever I shifted. It would come and go, it'd feel smooth and then out of nowhere it wouldn't be smooth again. It feels similar to when you sit inside a car when it's off and you move the shifter from gear to gear (a nonsmooth feeling). So this Monday I decided to empty out a bit of transmission fluid and add some transmission additive. I drove around and it did feel much smoother. However, it does not feel as smooth as it has always felt. The car runs perfect, it just comes down to my personal preference in smoothness.

My 2004 Golf GTI VR6 6-speed manual makes a louder than usual decelerating noise while in 2nd, 3rd, and 4th gears. If I give it gas it doesn't make any noise but once I take my foot off the pedal it makes a louder than usual decelerating noise. It sounds almost as if something is maybe grinding but I'm not sure what it is. One mechanic said it may just need to be serviced (new transmission fluid). I've read some forums saying it may be the bearings or maybe need a new transmission. The car runs fine otherwise and there aren't any problems shifting up, it shifts really smooth. '
Its only when I downshift that I hear the noise. The noise is the same no matter if I'm turning or going straight and and it's in neutral, there ISN'T noise. It's only while in 4th, 3rd, or 2nd while decelerating. Even if this is a common problem with VW's how do I fix it?! The previous owner said it's been the same way since he's had it and it has NOT gotten worse and his mechanic said it was nothing detrimental to the car so he left it that way. The GTI has 130K miles on it and runs strong, that's the only problem it really has. I'm not sure when the transmission fluid was last changed so that could be a possibility. Going to possibly try that in a few days and see what happens.

I am currently having a clunking noise coming from the front driver's side when accelerating from a stop or decelerating to a stop. It seems to happen only at low speeds and only on the driver's side. No strange vibrations or noise when turning or when going over bumps. I am thinking strut mounts or possibly trans mount.

Background facts:
Tranny swapped from my 4 speed auto to a 1.8t o2j 5spd
13lb. Light flywheel
Powerflex dogbone mounts
Peloquin LSD
The problem: Very hard to get a smooth shift from gear to gear. Trust me, I know how to drive, but I can always feel the car shifting into a different gear if you know what I'm saying. On my friend's bone stock Jetta, I just let the clutch out without gas in between shifts and you don't feel a thing.
On my car, you feel EVERYTHING. People have told me the light flywheel will make the ride more uncomfortable in many ways, especially since the RPMs drop much quicker in between shifts than stock.

I've got an awd 1.8t and ever since I did my 3" downpipe and cat delete I've had an oil smell both inside my car and from my exhaust. I thought at first maybe it was the valve cover gasket which I did last summer, but it looks to be fine. Also it does smoke out of my exhaust sometimes, but a buddy told me if it was my turbo seals my oil level would reflect the seals being gone, which the oil level hasn't moved. What else could it be? Do I just need to put a cat backin?

I have a 2001 Jetta 2.0L standard transmission I believe my exhaust manifold is cracked looking for a replacement. There is a local guy selling one off a 2001 golf wondering if that would work on my car..

So I acquired a 2003 1.8t GTi a little bit ago and i'm loving it, but I want it to be louder and more aggressive. With that being said I've already searched the forums but could not find anything for my specific case. I bought the car with a 3 inch downpipe and Borla muffler installed so I would like to know what way I can modify the exhaust to be louder while keeping these components in tact!

Putting a straight pipe from the cat back on 1.8T mk4? I was thinking going 2.5 inches from the cat back with a tip. But I wanna know how loud it is.

I am leaking coolant at a slow drip but over a couple days my coolant light will come on due to low levels. I climbed under the car and I'm leaking right where the o2 sensors are on the exhaust. The coolant is dripping down from the exhaust shield which was just hanging there when I got under the car.

So I have a 12v vr6 jetta and I really want a better exhaust with a nice clean and loud growl. My friend has a mk5 with a full Apr exhaust that sounds absolutely amazing and I want it to sound like that and I am willing to change my rear valance to the later mk4 jetta style if needed.

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.

Removing exhaust shielding and replace it with some other insulator?
The reason I ask is I am looking at, the very least, removing the shielding over the midpipe section and muffler section. Looking for experiences (pros/cons) with doing the work.

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?

My wife and I recently purchased a 2013 Jetta and have noticed some abnormal lag when accelerating. It's an automatic transmission and the gear shifts aren't as smooth as they should be. I have read that it is possibly related to the drive by wire system and may just be an inherent result of that system.

My exhaust on my 01 was rattling. It was coming from the catalytic converter, I assumed it was the heat shield. Put it up on the lift and lo and behold it was something in the cat that was rattling. I was popping a code for the cat anyways so figured I'd just swap it out. Fast forward to tonight. I get the car back up on the lift and I wiggle the cat but no rattling? I go farther back to the first muffler/resonator now it's rattling. It's not a hanger or a heat shield or metal to metal on the outside, there is obviously something of substantial mass inside of it I can almost feel where it is by wiggling around. I chose to wait and cut the exhaust up a different night because I plan on taking that section out as well now, hoping to get out whatever is rattling. If not I'll just have some spare pipe on hand to replace it.
