GTI 337/20th Anniversary :: Knocking Noise When Accelerate / Turn
This started recently and it's definitely out of the norm... When I activate my signal and it switches off, i still hear the ticking but no lights are flashing. it'll go on for about a few sec then shut off, sometimes comes on even when i didn't activate my blinkers. Also when i start my car i feel a vibration from under my feet. Sounds like a knocking noise when i accelerate/turn. But then goes away after about 20 seconds of driving.

Have a jazz blue chipped tuned with giac.. It does this random times.. When I come to a red light on idle the rpms go up and down just a bet but never stalls. The car vibrates and the engine shakes a bit. Engine is stable when car is on and off. Idk if its motor mounts or what?

I did a tune up on my 20th last week, plugs and coil packs and oil change. now i have a strange idle that it wasn't doing before. i checked all the plugs over again and they are gapped fine and i have no CE light on. Every now and then my RPM meter will jump down and then right back up, same with the boost meter at the same time. i had it looked at at the garage i go to and they said they cant seem to find anything wrong. What might be causing the rough idle? keep in mind this only started happening RIGHT after the tune up.

Okay, this all started a couple weeks ago when i first heard a weird knocking noise about 10 minutes after I left my house. I pulled the car over and it seemed to be coming from the right rear of the car. I started to turn around when it stopped. Over the next few days I notice the longer I let it warm up the sooner I hear the noise. I park in the garage and have read different things on the temp changing etc. About a week ago my check gas cap light went on shortly after I heard the knocking noise.
I pulled over to check if it was tightened and when i restarted it the light was off.... I didn't think much about it but this weekend it went on again, after I heard the noise and I pulled over to check it, tightened it and started. This time it did not go off. After letting the car sit for a bit and restarting it finally went away. Then again this morning 7/2 after hearing the noise the gas cap light goes off again...same thing as the last. Light will not go off... the car is parked right now and hopefully the light is off when I go back to turn it on.
Received error code P0445 now and gas cap light no longer on, check engine light now comes on. I had my bf locate the fuel pump and he ran it and the noise seems to come from there...(TY Savko@HSTuning). When he moved it the check engine light went off for about 15 minutes but eventually came back on. I read to replace gas cap first with a P0445 error so I ordered a new Gas Cap and if that doesn't work I guess the fuel pump will be next?
GTI 337/20th Anniversary :: Knocking Noise By Passenger Side Floor Board When Warmed Up
2004.5 GLI 1.8t. Its got 70k on the clock, its a Cali car, runs like a charm BUT... For some reason when it gets warmed up, it makes a knocking noise by the pass side floor board?
Its just at idle, i mean i can give it a little rev, and it doesn't seem to get worse so that eliminates bottom end or head... so???? Ive read some post on here that say... its nothing... just ignore it... but idk.
Like I said its just at idle and it sounds like its coming from the pass floorboard.... I left it running and popped the hood and couldn't hear it.
GTI 337/20th Anniversary :: Rough Idle - Car Get Close To Stalling When Falling From High RPMs
Just checking in to see where you'd recommend to start looking for a rough idle issue. It seems to get worse once the car fully warms up. I took a vid, and although it may not seem horrible in the video, it sometimes causes throttle lag from a stop and causes the car to get close to stalling when falling from high RPM's. Take a look at the video .....

So my car started to misfire when under boost so I had the car scanned the first time and came up with codes P0302, P0303, and P0304 which are all for misfires. I replaced the coil packs not even a year ago and the car drove fine as long as I wasn't in boost. My rpms would fluctuate a little bit but not much. I changed the spark plugs and it seemed to work a little bit but it would still misfire under higher boost. The one thing I noticed was my vacuum sits at around 15-17 in when it used to be around 19-20. I've cleaned and disconnected the MAF and the idle didn't improved. I also cleaned the MAP sensor and AIT and the CTS is new. I've done a pressure test and I found some leaks and fixed them but still no luck. Then yesterday my car started running really rough at idle and the cel would flash while driving then stay solid while stopped. Got the car scanned today and got codes P0300, P0301, P0303, and P0304.

I am after a annoying dash noise that I get when driving over any rough surfaces. I have removed all centre console and glove box and everything else around that area and I still have the noise, its like the dash is loose some where else, I have looked around for a complete dash removal instruction thread, but can not find anything??
It looks like I will have to remove the whole dash but really could do with some instructions on how to do this as I don't want to break anything!
GTI 337/20th Anniversary :: Serpentine Belt Noise At Idle When Turn AC On
I have a mk4 gli and I'm having a problem with serpentine belt squealing when I'm at idle and when I turn the ac on. It's isn't all that loud at idle but when I turn on my ac it gets real loud. My ac stopped working a little but after this noise started to happen. Could it be possible that it's the bearing in the compressor that is making it squeal or could it be somthing else?

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 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?

I just picked up a 20th about a month ago. It has 50k on it and recently I've noticed a faint whining coming from under the hood, most noticeable under idle and it changes pitch when I turn the wheel. I check the P/S fluid and it was low so I topped it off and I believe it has improved a bit but not too sure because I haven't gotten a chance to drive it yet. The steering does feel a little heavy but I figured that's normal because, well it's not a cadillac.

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 had a friend check out a noise coming from my engine, and he said he thought it was an "idle pulley", and another friend say it sounds like my injectors. Its kind of a tinny sound and it gets louder as my RPM's go up. I dont know where to begin for diagnosis, but I heard it on a different Jetta about a week ago.
View 4 RepliesGTI 337/20th Anniversary :: Grinding Noise While Engine Braking On 2004 Jetta GLI V6
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.
GTI 337/20th Anniversary :: Rough Transmission - How To Fix It
my 20th feels a bit off when im shifting. First to second can feel very rough (just not smooth at all but it does shift easily but takes more effort for a smooth shift. second to third is also a bit off but not as much. all other gears shift normal and smooth.
