Golf IV / Jetta IV :: 1999 - Knocking Sound At Idle
Nov 25, 2014
1999.5 gls vr6 ... 113k on the clock
Timing chain hasn't been changed yet .. Has new spark plugs & wires ..
Water pump was replaced & pulleys look fine ..
No CEL .. Yes there's oil in it.
I get a knocking sound at idle and it has absolutely no rhyme or rhythm which makes me think it's not a valve or rod(wouldn't that make a constant noise?). The sound comes from the passenger side floor board. Only happens at idle, and if you rev the engine, it will go away. Even if you don't rev the engine some times it goes away then comes back. Sometimes I hear it when i pull up to a red light real loud & most of the time the engine purrs like a kitten. I even sat in the car and told my dad when it was making the knocking/ticking noise and he went all over the top and bottom end with a mechanical stethoscope & heard absolutely nothing. Am I missing something obvious?

So I drove my R kinda hard today (nothing more than i have in the past ) but i am now getting a knocking sound. It is faint when I am at idle and get a bit louder around 2-3k, then the exhaust over takes it. i checked and have oil.. but it is making the knock as if it were low.

So, I have a 2005 gti 1.8t, has 110k on it, just did a 3" straight pipe, and while a buddy and I were installing my new pipe, and straight pipe, he said my turbo seals were going bad. I could get the k04 cause it handles better, or get a rebuild kit. Well, today when I give it throttle, it almost makes a knocking sound from the turbo? Not from the front of the car, but at the end of straight pipe, you can hear it in that constant spool. What could this be? Time for the k04. Car has unitronic stage 2, so it gets ran hard sometimes.

I've got a 2003 Jetta with the 20v 1.8t, today I was driving along and when I slowed down coming into town, my car started making this sound that I can only describe as sounding like a tractor. It sounds like something is rattling under the valve cover.
Here's a video with the sound : [URL] ....

My 2000 Jetta GLS is producing a clunking/knocking sound from the front end (possibly left-front) ONLY while coasting and going straight. It mostly goes away if I turn left or right and totally goes away when I give the wheels engine power or when I brake.
I recently replaced my front-left control arm due to a thrashed rear bushing. I didn't replace the bearing as I didn't have a pickle fork. Not sure if this is related.

Quick q recently just got a gli and I've noticed a knocking sound when accelerating and shifting from stops could this be my motor mounts ? I was thinking my tranny or clutch but everything runs smooth and goes into gear fine...

There is a knocking sound in the rear passenger side area. Cannot diagnose the cause, what it could be. I checked the bushings for the anti sway Bar but that was not it.

My 2003 Jetta GLI was making a terrible grinding/knocking noise when i would turn and occasionally make this "Bong" sound especially when reversing. I took it to my local shop and they say my spring in the front left is "either broken or unattached" and that i need spings/struts. I have like 150k miles on this car so the timing is probably right. So my question is, how much should they charge for this? Also, what should i have them order and install? Im not trying to lower or anything like that, OEM or a slight upgrade is what im looking for....

Not sure where to even start this but ill try to keep in concise. 03 gli 24v 6 speed. 125500 miles. At about 123500, i start noticing this slightly growly bearing sound at idle, without the clutch pedal pressed. When you press the clutch pedal, it goes away. Waited a bit, and at 125k, i replaced the clutch, flywheel, and throwout bearing, thinking it was a bad throwout bearing. It wasnt that.
Next, after more research, it seemed the 02m 6 speeds have had some issue with input shaft bearings wearing out making similar noises. So, pull the trans back out, and send it to APTuning in PA. Have new input shaft bearings, upper and lower pinion shaft bearings, and diff bearings put in. Even though they said they saw no major wear to be worried about in any of them. And here we are, left with the same noise.
One of the guys at APTuning said they had a case with one car where the thrust bearings wore so bad it made for a similar condition. Where the car would make unpleasant noise without the pedal pressed, and would go away when a load was put on it with the pedal. SO, i guess what im asking is, is there validity to that? What are the chances my otherwise seemingly fine 24v has this issue and end play is so bad that is causing this noise?
The noise gets NOTICEABLY louder when the car is hot. Its almost silent on cold starts. But after 15 miles or so it can be heard almost voice level with the windows down when you're stopped and idling; it really hurts to drive it being a caring owner hearing it. The motor is still in the car with all accessories so i can't check the end play scientifically. But to be fair, if this is plausible, and is the issue, i dont think it'd take precision to tell.
I'm so deep into this, and thought I've ruled out everything yet the noise persists. Really at a loss..
Listen around :30 where I start to cycle the clutch pedal. When I press it, you hear the main shaft "spin down" and the noise go away. When I release the pedal again, you here the clunk and the noise again. Its also been sitting for 3 hours. Good bit louder when hot [URL] .....

I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.

I have an '09 LS 460 AWD and there is a very unlike Lexus knocking sound at idle to maybe up to 20mph. best way I can describe is to imagine a diesel engine at idle, and dilute it substantially. subtle but clearly there. i read here in CL that could be due to valves or such, but dealer insists it is because of the intentionally designed "oversized fuel pump and fuel injector" and completely normal.

l have a 98 s10 with the "x" code 4.3l. While driving the cel started flashing and it lost all power. after got home i scanned the codes and revealed a MAF sensor error. replaced the maf sensor, which did not work. Then replaced the cap, rotor, and wires as they were burned through. This made the truck run fine when given gas, but makes a knocking sound at idle and stalls.

I have a 2011 xlt crew cab with the 5.0 v8.I have noticed a knocking sound at idle, it happens when the engine is cold or at operating temp. It doesn't do it all the time but more often than not.

I have a 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.

I have a 2002 1.8T with about 75k miles which makes a harsh rhythmic sound at idle after about 30 minutes of driving. If I tap the accelerometer to increase the rpm and release it goes away and is silent. Recently it also seems to be making the same sound when it starts but goes away as soon as I drive. The sound seems to be coming from the front lower right (passenger side).
I have changed the timing belt about 18 months ago (along with the water pump, tensioner, etc. using an ECS tuning kit) and it ran fine (seemed even smoother than before) but it had a small engine oil leak which my mechanic fixed. I think this sound started after he repaired the leak. I've left the car with him for a week and he just called and said it he couldn't figure it out but it could be an oil pressure problem but I have not had any issues with an oil pressure light.
I have had issues with the P0411 code over the same and have replaced both the secondary air pump and the combi valve but the code just reappeared and my mechanic says he has checked the entire system again and can't figure out what is causing the problem. Not sure if the two can be related but just thought I would add that. The car runs fine otherwise and I have always used synthetic and the large oil filter but I am beginning to think this could be a sludge issue (the noise).

My 2000 Toyota Corolla is making a knocking sound that gets worse when the car is in idle and in drive. I have a feeling that it is dying, but is it unsafe?

So was sitting at an idle in park and truck starts knocking, horrific sound. So shut checked oil, good, went to work came out 8 hours later, started up still knocked. Pulled into drive hit the pedal, knock went away, stopped at red light, knock came back...... Truck has been parked for 3 days, still knocks at an idle but soon as tap the pedal and give fuel it goes away... Tried unplugging injectors one at a time to eliminate, still had knock.

I bought my 2014 GTI TUESDAY... In less than 24 hours, I noticed a knock when the car was at idle with the clutch not in. Went away once the clutch was in. The car has 248 miles on it.
I am thinking it is the throw out bearing, but vw service seems to think it is nothing and they want to just run some tests and keep it for the weeknd. In all reality, I will have the rental longer than I actually had my brand new car.

Whenever I let off the gas there's a rubbing/knocking noise under the car, the sound will slow down as the car slows down but as soon as i press the gas pedal it starts again, it also doesn't do it if I am stopped and in neutral and rev the engine not sure what this could be?

Okay just installed a newer 24v into my existing 24v VR6 GTI both with 135k. I have heard the motor run before it was pulled and sold to which sounded fine. Upon receiving the motor I put new timing chains, guides, headgasket and new gaskets all around. The timing was right on the mark and I tightened everything up to torque spec and I'm getting this noise which sounds like it's from the timing cover area. A code just popped on which I'm going to scan as soon as I get my hands on one. The car was running great for about 20 minute and I shut it off then turned it back on about 5 minutes later and experiencing these scary noises. I tried pulling each individual coil with no results to get the noise away. What could this be?

WRD Coilovers on my MK4 GTI. I finished my install this evening, and on my first test drive I noticed a knocking noise in the rear. I believe it is the springs sitting a little loose. The front of the car is sitting a bit lower than the rear, so I believe most of the weight is shifted towards the front, therefore making the springs kinda free float? I jacked her up after the drive and kinda gave the springs a wiggle and they have a tiny bit of play, enough to hear the spring kinda TING against the perch. I suppose I'm going to raise the front a bit to try and distribute the weight more evenly.
