Passat (B6) :: Engine Knocking Noise When Enter The Freeway And Accelerated A Bit
May 6, 2012
I have a 2007 volkswagen passat 2.0 L...115000 miles. Yesterday I was entering the freeway and I accelerated the car a bit when I started hearing this noise on the engine. I will try my best and describe the noise as a knocking of metal on metal. I thought maybe is the oil and changed it.
Now today I was going up the hill and accelerated the car when the noise appeared again, it happened again a little bit later, again going up a hill. There is no noise when I drive normally or I accelerate and I am not going up a hill.

I have a 2015 Sonata 2.0T and I have noticed knocking noise when driving. I experience it more when on the highway/freeway. I mainly experience it during acceleration. Not hard acceleration but when I want to overtake or when the road curves and coming out of the curve -I step in the gas a bit, I hear the knock.

I've noticed distinct engine knocking noise under acceleration/load especially at lower RPMs on a '14 TSI. I'm at 20k miles and wondering if cheap gas from ARCO is the culprit.

Lately it has been in the 20's in my area and I've noticed on the first start of the morning the engine sounds very loud and produces a "knocking" noise that lasts a few seconds and then goes back to its normal loud idle. This only happens on the first start of the day...all subsequent starts in the day are fine. (mine is a 2007 model with the FSI engine)

My car had some knocking for maybe 6 months when I would accelerate. Today it started then cut off. I restarted it step on the gas now I have thick white smoke coming from the exhaust pipe. Previously when I thought it was a head gasket issues , I went in for a oil change they said no it was not a head gasket problem.

I recently had to replace my drive belt on a 97' dodge grand caravan sport 3.3 engine. The belt shredded and this is how i knew i had to replace it. Since i replaced it i notice a whine type of noise that increases in pitch as the engine is accelerated. The other thing I've noticed is that all electrically related operations work better as it is accelerated. For example, the air blows harder, the wipers move faster, and the lights brighten. Now i honestly can't say that it didn't do this before i changed the belt. I wonder if a bearing is going out on a pulley. I have noticed the same behavior on my daughters 98 sable. Also note that i did get all of the pieces of the old belt out from the pulleys and i did spin each of them to make sure the were moving without any resistance.

Background: During the last couple of weeks, this happened at least twice: I had to turn the engine for a good 3-4 seconds before it started, and after it did, the EPC light came on. The car drove normally (short lunch drive) and later started with no problem and no EPC light.
This morning, during some stop and go driving, it felt like the engine cutoff for a split second and the EPC light came on. The car then drove fine but the light obviously stayed on. Then on the freeway at 70mph, the engine cutoff, the RPM needle dropped to zero, but within a second or two it came back to life. The "STOP driving" sign blinked just once or twice during this time and disappeared." I can't say for sure, but I am almost sure the engine came back on its own before I cranked it. After that, it felt like it was about to go anytime, but that could have been psychological. Got to work, turned off the engine, turned it on again, and no EPC light!
I found his tidbit on the web claiming it could be the MAF. I also have had the secondary air pump code for the last few months. Could that also be triggered by a faulty MAF? Obviously, I am taking the car to the dealer tomorrow morning. I hope it will be easy to diagnose and fix. Otherwise, it might be time to dump the car?

I can hear a drone at freeway speeds coming from the engine compartment of my 99 Passat 1.8. I don't know whether this is normal, but it seems like the down pipe has a resonance/vibration. How to reduce this? Test pipe? Header wrap? Or is there something wrong that I have this buzzing?

The engine of our VW Passat 2000 quit suddenly while driving home on freeway. Night. Rain. We put on the flasher lights as we were slowing while trying to move to the right lane. No shoulder as we we were on a bridge. Do not remember being rammed from behind. Had a new battery installed one month earlier after VW mechanics could find no reason for intermittent non-starting of car which we had been experiencing. They had run "fault codes".

I drive a 99 1.8t Passat with 90,xxx miles. Yesterday I felt the car hesitate/jerk a little when it's accelerated to 35-40 miles per hour. I've had this problem in my past and it was a cylinder misfire. I would bring it to the repair shop.
My question is: Can my car last about 1.5 weeks? My work is 20 mins away. I can definitely avoid the freeway.

After a rotate and balance, car started shaking when I accelerated. It only shakes on acceleration. I thought I need and alignment so I had one. Didn't stop. I replaced all four tires, breaks, and rotors as well as the front axles. Still shaking when accelerating.

Yesterday on my way to work I accelerated after a stoplight and heard a pop, now my car sounds like a motorcycle going down the road. It sounds like its coming from the engine bay, I have time to get it fixed, but I need to know exactly whats wrong and roughly how much its gonna cost before I go get ripped off by a local mechanic. The car has 98000 miles on it, I honestly doubt its still under warranty.

On the way to work the other day I noticed a whining noise that got louder as I accelerated. When I got to work, I checked to make sure the belts were all ok and they were. When I got home, I inspected further. The noise was constant and got louder when revved. It also got louder when the a/c was turned from on to off. I figured it was the a/c clutch. Shop confirmed it's the clutch and bearing. My wife and I have owned the car since it was new and now it has 93.5k miles on it.

2008 R32 with 106K. Have always used Mid Grade (89) octane since owning. Drive approx 800 miles a week. Has always run exceptionally well up until about two weeks ago. Three weeks ago installed Borla Cat Back. Still Ran Great. After two weeks the engine started stalling out when you floor the car which coincided with the Heat Wave we just had. Several weeks in the triple digits.
VW Dealer did a diagnostic and found no Codes. VW dealer sent info off to VW and they said I had regular gas, (which I did have mid-grade). I was told to stop using mid-grade and use 91 0r 93 octane. Service Writer told me I had carbon build-up from regular gas.
Today I had the BW Induction Service done and no change, engine still stalls out. At this point, I a not sure how to proceed to correct the stalling. I am leaving tomorrow on an 800 mile business trip. the engine runs great up to about 3/4 throttle or when floored. I have filled up today with shell 93 octane and will continue to use 91 or higher.

I've got an 02 passat 1.8t that started knocking on me but its not all the time its only after it gets up to running temp. it will sit there an idle with no problem and run smooth. when you rev it up it starts to flash stop oil pressure. i have been running engine cleaner through it under a belief that it has become built up with sludge or carbon.

I have a 05 V8 with just over 1000 miles on it. The other day while driving with the driver window down, I had the trans in sport mode. As I accelerated quickly and got the rpm's pretty high, I noticed a rapid clicking noise coming from the underside of the car. It sounded like it was below the driver seat area. The clicking I heard sounded electronic, and can be best described as similar to the noise a playing card makes when kids put them in the spokes of their bicycles. The noise became apparent as the car reached the next shift point, and stopped after the shift. As the rpm's rose and it reached the next shift point, I heard it again. I have been able to duplicate the sound in tip mode as well, but I mostly hear it when it's in sport mode as it's easier to get the rpm's up before the shift.
I took the car in and took the service manager for a ride. He claimed he couldn't hear it. So I got my salesman to let me drive another 05 V8 and I heard it on that car too, but not as severe as on mine.

Noticed a minor ping from my 2012 SE 2.4 when accelerating. Seemed to be less noticeable when A/C was turned off. Only have 6,500 miles on car. The oil level was down about 1/3 a quart; I topped off and will test tomorrow.

I took my car into the dealer to have them check out the loud knocking/pinging sound from the engine. First time, they told me that it was normal. It bugged the heck out of me so I took it in for the second time. Note: I was given a loaner to drive and it happened to be another 06 Passat 2.0T and this one sounded fine to me. The lead tech did kind of agree that it was a bit loud. So, they replaced a new fuel pump and did an oil change....?? But that of course didn't fix the issue. The noise is so loud that I can hear it inside the car w/ windows up when I'm sitting in traffic or at the light. Also at night, I can hear it when I'm standing about 15 or 20 yrds away from the front of the car.
I realize that the engines will have some sort of knocking sound (my 330i does that), but shouldn't be this loud. So, does this sound normal? BTW, the dealer told me that they contacted VW engineers and was told that it was perfectly normal. I don't really buy that!! I've only had this car for almost a month (took advantage of the CPO w/ 2.9% fin) and I don't want to have to deal with this if this seems to be an issue. I guess who does, huh?

We have a 2009 2.0 Tiguan with approximately 60,000 miles. About 6 months ago, the check engine light came on so we took it in and found out the breather valve was stuck causing oil to enter the cylinder and causing misfires. Had this fixed an about a week later, the car acted up again. Took it in and removed & reinstalled the intake manifold. Both pricey fixes. The dealership said it was a problem with the 2.0 engine design. Now we have taken it in again to a local shop who is now informing us we will need to replace the intake manifold. He said the same thing about the engine design. Our concern is that this problem will need to be fixed on a fairly regular basis. We really love the vehicle but cannot afford the cost of this maintenance if it becomes routine and are considering trading it in for a Passat.
