Golf IV / Jetta IV :: Constant Faint Rattle When Idling
Jul 16, 2016
So I recently swapped my 2.8l 12v vr6 for the same engine because mine blew up, everything went good and the car runs great but there is a faint kind of rattling sound coming from the top of my motor, when its idling it will be a constant faint rattle. It gets worse as i accelerate between 3 to 4.5 rpms but then stops making the noise when i really start cooking so Idk if I just can't hear it or what. I've tried looking it up but i can't seem to find a video that has the same problems as my car. My father told me it could be my rockers or valves and others have told me it could be my timing chain or guides. I would love to just take it to vw to get it diagnosed but I don't have the money. I will try and upload a video of the sound ....

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.

My wife and I have a 2002 Golf, Manual transmission, 2.0L, L4, 8V with 178xxx ODO.
About a year ago I started hearing a very faint squeal that would always squeal, regardless of A/C use, no power loss is felt, in fact, the A/C works great and the car runs perfectly. But after a year of driving and 1 big road trip, the sound is now unbearable.
I recently replaced the alternator, belt tensioner, and threw on a new belt, but still, the squeal persists. After holding a rubber hose to my ear and moving through each accessory pulley with the other end of the hose, like a ghetto stethoscope, I know that it is definitely coming from the A/C compressor pulley.
I found a video on the Youtube that perfectly catches the same squeal (not my car, not my video) [URL]....
Since the A/C compressor has a clutch, and the outer pulley is constantly spinning with the serpentine and there is no noticeable difference in the noise whether I am using the A/C or not, I think that the outer bearings on that clutch need to be replaced.
Should I just replace the whole clutch and any good DIY threads on this? I've looked but all I can find is a DIY for a TDI, which I don't know if it's the same compressor or not.

Lately I've been hearing a constant click from what seems to be my chains side of the motor. Tensioners and chains were said to be done around 123k. After I've been driving it for a few minutes I hear the click. I thought it was the trans/ throw out berrying but when i push the clutch in and have it in gear i can still hear the click. It is not rapid like a tensioner like a tick tick tick, its like tick......tick......tick, could this be my top end of my block not receiving enough oil? I have a cracked oil pan, doesn't leak that often but i feel as if that is the source of the problem. Also I feel as if i lose power once i hit about 4300-4400 RPMs could that be because of low oil pressure?

I have a 2000 Jetta with the 2.0 automatic and just like the title states, I have recently developed a engine vibration that is felt at all times. It is much worse when the car is in gear. I only seem to feel it in the gas and brake pedals. It does not seem to depend on speed nor does it only occur at certain rpms. It feels like someone zip tied a vibrating back messager to my pedals. I want to find out what it is because on long commutes my foot begins to feel like its falling asleep. I can visually see the engine vibrating with the car in gear. I am leaning towards motor mounts.

Temp is at 190, runs great, coolant levels are fine, everything seems fine but there's a constant stream of smoke coming from my dipstick tube. Oil isn't milky. 2.0 AZG. Tried searching but only found threads for 1.8t's. Headgasket was done recently.

I have this annoying vibration that starts at 85-90 mph and stays relatively constant above that, but doesn't get super intense or feel like the car is going to fall apart. Its a light vibration that I can feel at 9 and 3 on the steering wheel.
Background: So about 6 months ago I realized my CV boot was torn. I tried to replace CV joint, but they sent wrong joint(Meyle) so we ended up trying to force it onto the CV shaft for like an hour before giving up. I remember one of my BMW Technician buddies literally smashing the joint onto the shaft with a plastic mallet but it just wouldn't go over the circlip.
We ended up just replacing the boot and putting the old CV joint back on, but we didn't have any extra grease to put in it because we had already put it into the new joint that wouldn't fit. Since then I've basically tried everything I can think of, including:
-Balanced and Road Forced
-Laser Alignment
-Replaced all 4 tires
-Fixed bent rims
-Refreshed suspension/steering:
-All new F+R LCA bushings
-New inner/outer tie rods
-New ball joints
-New sway bar bushings
-New strut top mounts
So what the hell is keeping her from being smooth as butter over 90? Did we screw up the shaft by beating on it? Or is it just vibrating from the lack of grease/damage from torn boot? Was I supposed to align the shaft when putting it back on or something?

Finally got around to replacing my Thermostat because the DIY here made it look so much easier than removing the alternator and such. Did everything exactly as described and after assembling everything with the new t-stat and O-ring I am getting a constant leak from the housing. I tried removing everything and reassembling...all the bolts are tight. Plastic housing isn't cracked and seems to be in great shape. Everything lines up properly but coolant is just running out of the bottom of the housing. Am I missing some magical trick here?

Just installed raxle on my driver side. All clicking sounds are fixed but I noticed if I take right turns sometimes you can hear a constant clunking sound coming from the driver side wheel. It doesn't happen all the time, you kinda have to turn and hit a certain angle of the steering wheel. Also, only happens when driving low, if I raise the car just a little bit its gone. Never had issues with my oem axle binding so Im not sure how exactly does the binding sound?

I just got home from a 650 mile trip and I have pinpointed something I have been hearing for a while but couldn't figure it out. It's a very very faint rattle (something like the sound a hard drive makes) and it seemed to be coming from behind the dash. I experimented a little today and this is what I noticed.
It is actually coming from somewhere around the gas pedal and it only does it when you are neither accelerating or decelerating. In other words, when the engine is at equilibrium if that makes any sense. It's a tiny sound and I should just turn the radio on and forget it, but it's just one of those little things that bugs ya.

I have a 2009 Corolla 1.8 with 18,000 miles on it. My wife mainly drives it, today after getting it washed, I was driving and noticed a very faint noise from the engine compartment. Seems to be coming from the passenger front. The sound is something like grr grr grr.... I made sure it's not the wheels by putting the car in neutral and giving it gas which made the sound audible (I can also hear it while idling).
I had my wife sit in the car with me, and she couldn't hear anything, but I can, so I'm afraid when I go to the dealer he will say the same "I can't replicate the noise". What it can be?

We have a 2001 Jetta 2.0L with 170000 miles. The AC had been getting weaker, but now it only works when the car is idling. Which seems really odd???
Started car, after being parked for a while, and the temp was 73F at the dash vent. I figured it would get colder going down the road, but it got up to 90F at the vent. Returned home and let the car idle for a while and the dash temp went down to 80F. Went for another drive and it immediately raised to 90F.
The compressor clutch was engaged and spinning, but the larger metal line at the firewall didn't seem very cold. The smaller line was warm as expected. I added some R134a, but no change at the lines or in the car. We have had issues with the blend flapper and replaced the broken plastic part. You can hear the flapper slap when you rotate the dial from hot to cool, so it seems like it's working.
Could it be the compressor? I think it was only generating 150psi on the high pressure side during idle, but it would go up to 200-225psi when I revved the motor.
Replaced the valve body solenoids, increased pressure to clutch packs 8 clicks, added pentosin, cleared engine light, and the tranny is working perfectly.

Today I drove my 2006 G2 Prius with 59,000 miles to the park and had the windows down. I climbed a hill for a good while that had the engine under load and there was a concrete wall beside me, and I could hear a very very faint metallic-like rattle. I mentioned it to my partner who listened and said he couldn't even hear it, so maybe it is just me.

My gf's 04 gti 1.8t 5spd is having idling issues. Here's the rundown, at idle it sits at 800 rpm but when given a rev it then becomes erratic and fluctuates between 500-1100 rpm. When throttled again lightly it returns to normal 800 rpm idle. The car will try to stall a little bit. Now for the codes and lights. The lights are the traction control light and the check engine light. The codes are p0102 (MAF) and p2181 (coolant system performance). I have recently had a misfire which I took care of with 4 new coil packs. I kept the 3 good ones I took out. I have to change the plugs still but don't think it's an issue. Has new clutch and sits at 148,852 miles.

I have a Golf GTI IV 1.8T Tiptronic and having this problem when the car is Idling i can feel the engine vibrations trough the seat and are anything but soft, especially if the trany is neutral and less if leave it in D.
I've changed the dog bone recently, wich was very bad, but the vibrations didn't smooth they remain the same but the driving improved, so the dog did replacement was good.
The next step would change the engine mounts, but they look goof and I don't want to start change parts just in case. Where I live car parts aren't cheap and some times new ones are just crap.

But I have a mk4 gti 1.8t awp and recently it's been going downhill. Right now my only mods are a fmic, Cai, and a 3 in catless dp to a 2.5 in straight pipe. My car recently starting idling very rough and would practically die, the lights would also dim. While casting the idle was very rough too. Then yesterday my car started idling even worse and dying multiple times, plus my turbo stopped boosting and making what I presume to be the "death whine".
I replaced my spark plugs a few days ago and I checked my timing belt and it looked fine. I couldn't find any vacuum leaks either so I'm not sure what would be causing the rough idle? My valve cover gasket leaks and makes my sparks plugs covered in oil but I don't know if that could cause the rough idle. I unplugged my maf and ran it and there was no improvement.

I have had my 2010 GS450h for a few months now and about a month after I bought it, I noticed a faint rattle from the steering column, almost like there is a loose bolt or something. It is getting more noticeable (especially on broken pavement/rough roads) It's annoying and the only issue I have with the car.

yesterday I heard a faint rattle coming from under the hood while the a/c was on, when I had my son turn it off, it went away. Right now it's barely noticeable, but I don't want it to turn into something major. I own a '08 ES with 88,000 miles and all my service is done at the dealership.

I have a 2004 Jetta w/ the 2.0 engine, auto transmission. Lately it has developed a very gassy smell when idling. Could be all the time I guess, but I only ever notice it when idling. It seems more noticeable on the passenger side of the car, or maybe my wife just has a better sense of smell than I do since she noticed it before I did.
The car seems to run fine, about the same as it always has. The idle is slightly rough, but it has been like that ever since I got the car. I got it with about 110,000 miles on it and had the timing belt and water pump replaced as soon as I got it. Mileage now is about 130,000. No info on the maintenance history of the car, but when I had the timing belt changed they said it looked like it was probably the original one.
The check engine light has never come on. I think I'm due for some new spark plugs so I was going to be replacing them soon anyways. Not sure what to check out here that might be causing this?

When I'm idling and I rev the engine to exactly 1200 rpm i can feel an extra vibration coming from the engine. If i hold it at this rpm it will continue on. now this is not a violent vibration but more so of a buzz i can feel that travels to my steering wheel as well. what could it be ?
Another question is when i travel up my driveway and i hit the sloped curb at a angle i can hear a specific "clunk" sound coming from around the drivers foot well area what could this be? perhaps my axle going bad? I also heard it when I was reversing out of my parking space while turning.
I am new to this car and trying to make sure I'm doing everything i can to put it into good shape.
