Passat (B6) :: 2006 2.0T - Rumbling Noise When Cold


Nov 18, 2012

I have an 06 with the 2.0T that is making a rumbling type noise when you give it gas and also when you let off the gas. From what I can tell it only does it when you first push the gas pedal and stops if you are at a slow cruise and then of course does it when you let off the gas. The noise stops all together when the car warms up ( about 5 or 10 minutes) and has only started this over the past week since it's gotten cooler here. Noise seems to be coming from the drivers side but to be honest i have not had the hood to investigate yet so I can't be certain. Other than the noise the car runs and drives fine. Car just turned 101,000 miles so it makes sense that i'm having issues.

Downpipe was replaced about a year and a half ago
Cam shafts, high pressure pump and etc replaced April of 2011
Intake flapper was replaced in May

Civic - Honda :: Low Rumbling Noise At Cold Start

So for the last week my Civic has been making a low, rumbling sound (almost like an overly powerful bass system or a muffler) and vibrating whenever the car is idling from a cold start. The noise is most pronounced when the car is started but continues for a short time while I am driving, but only when I take my foot off of the gas in low RPM (below 1.0k). Whenever I accelerate, the noise stops, but when I go in reverse the noise is becomes louder. Also, the noise is very faint from outside of the car, but very pronounced from inside. After about 20-30 minutes of driving it usually goes away. What could be causing this?

Passat (B6) :: Rumbling Noise From Under Dash On Passenger Side Of Interior

Every two or three starts in the morning i will get a strange rumbling noise from under my dash on the passenger side of the interior. what would be making this noise? What is located under the dash between the passenger compartment and the firewall? i have opened my hood to investigate but do not see anything under there that would make the noise. it almost sounds like the auto leveling compressors that are on some GM vehicles but i know this car does not have that feature.

Passat (B5) :: V6 Shaking A Lot And Making Small Rumbling Noise On Startup

I own a b5.5 2.8l 30v v6. Today I went to get in the car and on start up for the first time in 3 days it started shaking a lot and making a small rumbling noise, sort of like a cylinder misfire. This isn't the first time its happened. I tried searching this up and everything seems to point toward the fuel injectors. In this past 6 months my average mpg has dropped from about 20 to 16.

I am guessing it is this, but someone also said it might be a cylinder misfire. What exactly is causing this? Also in the 1 year of owning it, it makes sort of a diesel sounding noise in the engine. Some people have told me it might just be the valves that need to be adjusted but I have no clue.

Toyota - Vibration - Rav4 :: 2006 - Light Rumbling Noise As Drive Down The Road

My 2006 RAV4 Sport 4WD, 80K miles, is making a light rumbling or light vibration noise as I drive down the road. It's intermittent, and will generally stop making the noise when I let off the gas (auto trans). It happens at different speeds and will always quit if I let off the accelerator, but doesn't always quit if I step on it. It's just faint enough I can tell it's there, and doesn't sound or feel very severe. I probably would never notice it if my stereo was on. I thought it might be my Bridgestone tires, which have less than 10K miles on them, but I would think the noise would continue even if I let off on gas.

Lexus GS 2006-11 :: 2010 - Rumbling Noise When Accelerate From Dead Stop With Wide Open Throttle

So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.

I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.

Elantra HD (2006-10) :: Extremely Loud Rumbling Sound At Any Speed

I have a 2010 Elantra Touring, manual transmission. At about 30,000 miles it developed an odd feature which continues through the present time with just under 50,000 miles. At any speed and on any road from time to time I suddenly get a loud interior noise like driving right next to a train running on a track. There is no vibration, just a very loud rumbling sound drowning out the radio. Goes away after a few minutes, does not recur on the same piece of road, same temperature, or same time of day. When it first occurred the dealer inspected it and though they could not hear it they divined that the aftermarket cruise control mounting bracket had become loose and was vibrating. They tightened it and the sound went away for a year but is now back louder than ever. I checked the bracket and it is tight and the dealer can find nothing loose. The bumper to bumper warranty is about to expire. I am thinking a crack in a steel bearing surface or a bad weld causing a vibration running through the body. Again I feel no actual vibration through the steering wheel.

Passat (B7) :: Audible Rumbling With Vibration At Front / Mid Of Vehicle Under Specific Circumstances

2014 Passat 1.8T Gen III manual... Experiencing an audible rumbling with vibration at the front/mid of vehicle under specific circumstances.

*93 octane tune (high torque at low rpm)
*barely perceptible in 3rd, but more in 4th and very much in 5th
*about 1700-2200 rpm ONLY when deep into boost - as soon as I even slightly reduce torque, it goes away
*seems to be related to engine firing frequency (i.e., 2000 rpm = 66Hz firing frequency...still audible and tactile at same time)
*not related to road speed
*sweeping through problem area in 1st or 2nd goes too fast to develop the rumble.

Hypotheses:

*half shaft shake (torque related dynamic runout)
*engine mount/trans mount groundout from torque reaction
*exhaust system ground out due to torque reaction.

It doesn't feel like a misfire, not slipping clutch. I would hate to have to get a 91 octane tune or just avoid the sweet torque at 2k!

Camry 2012+ :: Low Level Rumbling Noise At 45 Mph Or Up?

2013 Camry SE. I hit a curb pretty hard on the right side. Dealer replaced both tires and wheels and lower control arms on the right front. $2,400. Now I notice a low level rumbling starting at 45MPH or up. Very little change in the noise as speed increases.

I'm wondering if they missed a damaged bearing that is causing this noise? I had the dealer test drive it and they can't seem to hear it.

Honda - Fit :: 2007 - Knocking Noise And Rumbling

I have a 2007 Fit, and just recently started to have my car rumble, specifically the break pedal, when I break. We got new breaks about two years ago. I'm just wondering what it could be. Another thing is I was driving and some (explative) person decided to pull out in front of me when they really shouldn't have. I slammed on my brakes and had a grinding noise and feel to my car when that happened. Since then when I'm driving slow I get a knocking feeling against the foot area of my passenger seat. What could this be? It is kinda hard to look underneath the car since it is so low so we can't easily see by the wheels or Axel area.

Camry :: Rumbling Noise With The Vibration Continues With Driving

2006 camry LE - 4cyl - 140k miles

[URL]....................

The car idles pretty rough & loud but ive noticed its only when im in 'drive' with my foot on the brake, at stop signs/lights. Its also much worse when the engine is cold. It settles right down if I come to the stop and shift into 'park'. So as I roll to a stop and hold the car in place with the brake the engine starts vibrating.

I dont know much about these things but it almost feels like i'm restricting it by having my foot on the brake and the engine wants more gas or air or something (could be way off base, but thats how i perceive it)

The RPMs sit around 1,000 and as the engine idles/rumbles it gets up to maybe 1,200-1,400 RPMs which i didn't think was significant but im pretty new to this.

Forgot to mention the most important thing- there is a rumbling noise that goes along with the vibrating, again only while stopped, goes away immediately when i pull off the brake and hit the gas.

Toyota - Rav4 :: Rumbling Noise Happen When Car Shifts Down

2007 Toyota RAV4. So the car (suv) has around 180,000 miles on it. It's my moms and has been a good car so far. Not too long ago it started making a noise. She (my mother) took it to several shops and best anyone could come up with was a "transmission" issue, without any fix. I've noticed when driving it that the noise only happens when the car shifts down, like you're going up a hill and it shifts down. It makes a rumbling noise kind of like when you sit your cell phone on vib and it goes off on a table. It doesn't seem like it hurts the cars performance any just a bad noise.

Toyota - Rav4 :: 2007 - Low Rumbling Noise At Around 1500 RPM

My Rav4 experiences a low rumbling noise at around 1,500 RPM. The noise disappears if I let off the gas, or speed up. I have brought the vehicle to 3 different repair shops, including a transmission place, and nobody has been able to give me any answers as to what the problem is. One place said that it sounds like it's in the tranny or transfer case, and that it feels/sounds like it's going into the torque converter lockup too early. The vehicle has just over 60K miles on it.

Elantra HD (2006-10) :: Engine Stopping / Rumbling When Change Gears Occasionally And Sometimes At Stop Sign

My 2007 elantra has been rumbling when i change gears occasionally and sometimes when stopping at a stop sign the car just dies. The car starts right up though as if nothing happened. It only happens like twice a week but i really want it fixed. I already changed the motor mount next to the engine block on the left. Could it be the motor mount connecting to the transmission?

Cadillac - Cts :: Rumbling / Chattering Noise When Turning At Extremely Low Speeds

I've been experiencing a low rumble/chatter type noise only at extemely low speeds in conjunction with turning the vehicle (as you would in a parking lot). You can also 'feel' this noise to a slight degree on the steering wheel. This event happens going forward or in reverse. Additionally, it seems to be coming predominantly from the rear of the car. This has been going on for several months. My mechanic has ruled out any recall notices, tires, and brakes. He suspects it may be the drive train?

Jeep - Grandcherokee :: Rumbling Noise From Back End When Start To Accelerate

I have a 2007 Jeep Grand Cherokee that I absolutely love, but lately a I've been noticing a problem with it gradually getting worse. When I am on my way to work in the morning, and I get on the on ramp to the highway, as I start to accelerate the back end of the car starts to make a rumbling noise. When I look at my gauges the rpm's are going up and down kind of like it doesn't want to shift. The only other time I notice this is when I try to climb a hill on the road or highway. There is no check engine light on. I have had this problem for quite sometime, but just recently noticed it because it has gotten worse. My husband has had a few mechanics drive it, and has asked a few others about it. They either don't know or have a very wide range of things it could be. My friend I work with had a Pontiac Grand Prix. She said that her catalitic converter plugged up and caused her transmission to go out.

Passat (B6) :: 2006 - CEL Just Came Up / Cold Start Misfire

Bought a 2006 (later production) with 25,000 miles over the weekend. Couldn't pass up the price and the warranty (1 year left + CPO). Picked up the car Saturday at noon..... had to drive to DC for business and the CEL came on when I turned on the car this morning. I researched at lunch that it could be a cold start misfire but I am already pretty heated about this. When I get home tonight I am going to plug it in to my OBDII scanner and see what I can pull. If it is something bad.... I am giving it back to the dealership.
