GTI 337/20th Anniversary :: Weird Rattling Noise When Engine Braking
Aug 7, 2008
I recently installed my 3" GHL exhaust along with my stage 1 BFI dogbone and I recently noticed a very faint rattle when I am engine braking. I can only hear it when there's no cars around or when its quite. but i cant figure it out. (I still have the stock exhaust heat shield in from the cat back so I am not ruling that out as a possibility).

I just picked up a 20th and it seems when it's running and parked i get this very distinct rattling noise from somewhere in my engine bay. I go to put the clutch down and it stops, as soon as i lay off the clutch it comes back (almost humming) could it maybe be the trans?

2004 Jetta GLI V6 24v 6 speed ... This started a few years ago, but it was happening in 3rd gear only -- therefore I avoided engine braking in 3rd gear all along. The noise was a pretty loud, noticeable grinding/spinning noise. 3rd gear while accelerating or maintaining gas worked and still works perfectly, smooth as can be.
Somewhat recently (6mo-1yr ago) all the other 5 gears started making this grinding noise, some more than others. 1st gear I don't really know because I don't engine brake in 1st. However, 2nd, 3rd, 4th, 5th and 6th (barely noticeable but still there) all make the noise. I now of course avoid all engine braking, however even the transitional steps between gears can be heard sometimes ... unless I perfectly match the RPM etc, but I'm just trying to get to work and back here ...
The car is still quite drivable, but with a major obstacle (pain in the ass) and a new clutch is probably around the corner -- I have 107K on it now. However ... a few years ago when it had 26K on it .. it didn't need a new clutch yet 3rd was still making that noise.

I've been getting a weird whining noise when I am slowing down, either in gear or neutral. Sounds like its coming from the driver side.

So I really don't drive my car much during the year since I'm away at college. Once I got back home a couple weeks ago and drove my 20th, i heard a rattle coming from the middle of the car. Jacked it up and starting banging around. The sound is coming from my resonator. Its either the clamp that is busted or the resonator itself. I have to get in closer to see which it is. But I do have a few questions. If I just cut the resonator cut off and weld a straight pipe to that will it be much louder. I have a stock 20th and I'm not really looking for a loud exhaust at the moment. Is it much louder without the resonator? I know if you put a straight pipe in place of the muffler it is MUCH louder so I'm just curious.

Every time I let off the gas in third and now fourth, the engine produces a higher and almost rattling whine. As soon as i add gas it goes away and everything sounds normal. There are no other symptoms and nothing seems to be going wrong but i have no clue why my car does this. Tried searching around but i can't seem to find anything.

Having this problem where the button to release the hand brake rattles constantly while driving? The only thing I can think is to replace the spring in it, but Idon't know how difficult that would be. Otherwise my only other thoughts are to find something thing enough that I can slide into it and hope it doesn't ever jam it up.

My 337 didn't pass inspection (control arms, inner tie rod, no cat because the guy I bought it from sucked etc) but it sat for probably 3 weeks and I just sold my other car (I was planning on using that $2000 to get the 337 to pass inspection) but I just drove the VW down the street for the first time and it's making some scary sounds.
Basically when I give it throttle there's a high pitched whirring sound and something keeps rattling that sounds like its coming from the engine bay. I'm really freaked out, I'm leaving in two months because I'm transferring to a new college and I need this thing to run perfectly.
It's also shifting a little strangely and if you don't shift absolutely perfectly then it starts to rattle (not like you're about to stall but something completely different) I can't take it to a VW dealer or anything because I'm way over the 15 days past a failed inspection and I can't afford a tow.

For the life of me I can't figure out what is causing this smell. Its got a little over 65k miles and for whatever reason when I'm driving at a steady 70-75mph on the highway I get this garbage like smell that can last between 2-6 sec or so with or without the a/c on. It appears to have no effect on the car though. I'm not overheating, I'm not losing any power from the motor, my clutch is still very smooth and no signs of slipping, my idle is solid as a rock, and I can't find any fluids leaking at all. It does seem to happen more frequently as the outside temperature increases and it is a very potent smell. I just can't find the source. It has only happened while I'm on the highway and have had absolutely zero luck finding that same smell when I've got it parked with the hood up.

I have the po411 code, not sure which problem it is but when I first start the car it sounds awful like almost a grinding or rattling noise then stops after a few seconds.

I just put on a magnaflow cat-back exhaust and sometimes when i idle i have a rattle and sometimes it will not rattle. I went under it and shook all around to see if anything was hitting but there was nothing i could see. What could it be?

Had it done at 87K years ago. Coolant light came on car had been rattling. Parked and coolant came leaking out. At 157K now was gonna replace belt at 167k, that's 80k since the last job. My guy says had I drove it further would be looking at a new 1.8t.
Does this sound about right to you since it's been 70k since that last timing water pump job. Why didn't the car overheat? Chipped at 40k with apr and very conservative driver. I suppose it just depends on too many variables why the job needs to be done 10k before I originally planned to do it.

So, it's been 8 years with this awesome car. Still enjoying every day. Over the past year or so, I've noticed my engine get gradually louder and louder. By that I mean, the overall engine noise at low RPM. It's a mechanical kind of noise. Clicking, etc. The engine has 101,500 miles on it.
For the past 2 days now, this noise has gotten dramatically louder. I've tried to capture it in the video below. Might have to listen with headphones. The noise is most noticeable at idle and then goes away after about 2000 RPM. You'll see. What this might be? Btw, there is no reduction in the performance of the car.

I recently just put a set of b&g rs's on the car and now it appears that my 3'' exhaust is hitting and rattling/striking the bend that goes over the rear axle, I know I can raise the car and keep it from doing such but that kinda defeats the purpose of lowering the car, Just trying to see if there is something out there, like polyurethane hangers or something along those line that might alleviate the problem.

I have a 42 DD tb exhaust. And so far I've used a 3" exhaust clamp over the last hanger (after the muffler) which raised the exhaust all the way up against the heatshield, eliminating the rattle over the rear axle beam. But the exhaust was rattling against the heatshield.
So I bought 15 ft of exhaust wrap and wrapped the section that comes in contact with the heatshield. It worked a bit but it still rattles a little! I hate this rattling! How to get rid of the rattling? Should I just use more exhaust wrap?

I've been trying to locate the source of the noise that is coming under the car. Specifically below the handbrake. Like something is lose, took the car to a shop to have it inspected, checked the exhaust, and there was nothing there, all clamps there and screws.
It only happens most of the time when the car is cold and it feels all the way from the hand brake to the stick shift. Sounds like a rattle like something is about to go off from the car but I cant imagine what could be. Couldn't replicate the noise at the shop, only when you are driving and the car is in inclined it rattles really bad until the car gets back to the normal position. Specifically in 1st gear .

My 1.8t gli is giving me this issue, when braking (specially hard) my steering wheel shakes side to side, my rotors got changed less than 20,000 miles ago (all of them) and they seem fine right now.
Could this be my Tie Rod ends? The car has 110,000 miles on it, and i know some bushings if not all need to be changed, which I am gonna be installing when i put on the Raxles i just got.

Having trouble with front brake pads rattling? About a month ago, I replaced pads - rotors - caliper pins on my 20th GLI. I know these cars ride a bit stiff but it sounds like my front end is about to fall off. All brake parts were torqued to spec - I've gone through all T25/T30 torx front end screws etc and I just can't find the rattle??? This has only started within the last few days. Any other places to check for obvious loose bolts etc?

Have a noise coming from their engine bay that kind of sounds like a bird chirping, but when you depress the clutch, it stops?
