Golf/GTI VII :: Buzz Or Vibration Around 2800 - 3400 Rpm Under Moderate Acceleration


Jan 10, 2016

So I just had the 10k service done on my GTI and after I got it back everything seemed fine. That is, until under moderate acceleration there was a weird buzz or vibration that came on around 2800-3400rpm coming from what I think is the engine bay or near the firewall on the passenger side. I was able to repeat the issue multiple times and it showed up every time. However, with the car at a stop and in neutral and revving it I can't make the problem occur only when under load, in gear, and traveling at speed. If I could describe it, it sounds like a playing card against bicycle spokes (for those of us who did that when we were kids)..

Anyways, I drove it straight back to the dealer and at that point had closed their service shop but they did do the right thing and give me a loaner car until they can look at it on Monday. How the heck could this pop up after a 10k service? What all do they do besides oil change, tire rotation, and fluid inspection?

I did pop the hood and one of the side of the fuel rail sounded louder than the other, I suspected that maybe one injector is starting to go and it seemed like an isolated noise but perhaps its not an injector at all. Nonetheless it seems this is a non-related issue..

Golf IV R32 :: Prominent Vibration / Buzz Under Heavy Acceleration

Just bought my R a few months ago and love it so far. I've recently encountered a slight buzz or vibration. I'll get down to the nitty gritty and not bore you with long drawn out information. Basically under heavy acceleration the driver side vibrates/ buzzes down by the floorboard. Now this only happen under heavy acceleration. I even did a test in 1st gear. Heavy accellerate under 2k RPM's, 3k RPM's, 4k RPM's and the vibration happened under these heavy acceleration periods. It's almost like there was also a loss of power during this vibration/ buzz, which leads me to believe it might be the clutch.

I took off the prop shaft and drove in FWD for a few weeks. The vibration was still prominent. Took of both front driveshafts and inspected those and they seem perfect but THE VIBRATION IS STILL HERE. Could this be the clutch?

Ford Super Duty (1999-2016) :: 2008 V10 - Consistent Metallic Buzz On Moderate Acceleration?

Over the past couple of weeks my truck has developed a pretty consistent metallic buzz on light/moderate acceleration. At first I thought it was a heat shield rattling, but I've been under it a dozen times and can't find anything loose to make the metallic buzz that I'm hearing... I can pound on several places in the exhaust system with my palm and it seems solid/connected everywhere. V10 truck??

Santa Fe (CM - 2007-12) :: 2011 - Vibration With Moderate Acceleration And Only Sometimes

2011 SF. 52000kms.

A little while ago I noticed a brief vibration (felt through floor and steering) with normal acceleration from stand still... I attrributed this to the cold weather and perhaps oil thickening, as the problem went away after the car was warmed up. Since then I have noticed that it's continually happening on a regular basis, but only for a short period.. I was still thinking that it was the cold, but that wasn't the case because I left the car idle at start up for 20 minutes until well warm.

Now.. If I slowly accelerate (not putting much load on the car) there is no vibration at all. When the car reaches a certain speed, the vibration goes away. There is also no vibration after about 15 minutes of driving.

I had a neighbor test it with me to confirm and he felt it, and initially thought differential oil, but then suggested myriad other things from the CV boot to bearings to etc etc.

I need to take it to the dealership so they can experience the vibration but would certainly need to leave it there over night so they can check it out when "cold".

Mitsubishi - Lancer :: 2002 - Vibration Under Moderate To Hard Acceleration

Vehicle is a 2002 Mitsubishi Lancer with 123,000 miles. During moderate to hard acceleration in a straight line, especially in gears 1 to 3, the front of the car vibrates. The harder I accelerate, the worse the vibration gets. Once I get into 4th gear and get up to 40 MPH, I can put the pedal to the floor and while it will do it, it is very slight. Check engine light is off.

Interestingly, on the way to work there is a 25 MPH cloverleaf and coming out of the cloverleaf onto the highway, it did not do it until the wheels were pointed straight ahead.

Deceleration, even when aggressively downshifting, is vibration-free.

I do not believe it is ignition related - the car idles fine, has plenty of power under hard acceleration, and doesn't do it when going around that cloverleaf. (As a side note, about a year ago a plug wire went bad, leaving one cylinder with no spark. In this case the engine vibrated violently, but was obviously down on power.)

There are no strange noises in the front end. No clicking around corners typical with a failing constant velocity joint, and no mechanical thuds or sqweaks over bumps I'd expect from a failing ball joint or bushing.

I am having some unusual tire wear on the outside edges of the tires, like you would see with under-inflation, but tire pressure is fine. In my mind, this points to bad ball joints.

It still has the original constant velocity joints and axles as well as the original ball joints. The one motor mount I can see looks okay. I'm thinking in order of liklihood (most likely to least likely):

1) bad axle
2) bad ball joints
3) bad motor mount

Anything else I need to check? Wheel bearings? If I do replace the axles, I will replace the front wheel bearings while I'm in there.

Camry 2012+ :: Intermittent Buzz Or High Frequency Vibration Under Slight Acceleration

2014 Camry, 4 cyl. 65K ... Wife's car has developed a vibration that is going to be hard to get a dealership service group to troubleshoot due to randomness. I drove it for 30-45 mins today and have this description:

-Vibration, either described as a 'buzz' or a 'high frequency vibration'
-Happens in the 28-38mph range (different points)
-Under very slight acceleration. (hard acceleration efforts produce nothing)
-Can't swear to it, but feel like it is always in 'high' gear
-feel it in 'seat of pants', NOT through the steering wheel
-Is faint on sound, but you can hear something
-Is typically only a second or two
-Is very hard to 'create', but then happens unexpectedly.
-My wife first reported it to me, and I took my son on the test drive today and he could feel it as well when it hit, but couldn't pinpoint it as it comes and goes so quickly, but again, you feel it in the seat/butt more than anywhere else.

I've checked lug nuts to try to eliminate something easy and they are fine.

Since it is relatively slow speeds and under very slight acceleration, can there be a 'solenoid' that is creating a false shift effort, but just vibrates the trans instead? Without any info other than what I have stated above, I'm leaning toward transmission, but again, probably not enough info to go on....

Golf/GTI VI :: Hesitation Under Moderate Acceleration In Second And Third Gears

Was back east this past weekend seeing some family. Went out with a friend of mine, who has lent me his 2011 DSG GTI APR Stage 1(car currently has 24k miles) many times in the past and it has always performed flawlessly.

We were out the other night and the car hesitated under moderate acceleration between 3500-4500rpm in second and third gears. It almost felt as though it was bucking a little, really odd. The hesitation comes in threes or fours, then moves on in the revs.

Golf/GTI VI :: Vibration And Pulsing Under Moderate To Heavy Braking

I've a little over 60k on my '12 Golf TDI and I think it's time to replace the brake rotors and pads (a lot of vibration and pulsing under moderate to heavy braking). I'm looking to replace front and rear rotors at the same time, but have a question about the rear rotor size:

Websites like Tirerack & Partsgeek give several options for the rear rotors - 256mm, 260mm and 272mm.

Golf/GTI VI :: Mild / Moderate Vibration In Steering Wheel Above 70 Mph?

2012 gti, completely stock, 21,000 miles. Perfectly smooth ride right up to 69mph, then mild/moderate vibration in the steering wheel at 70+mph... figured it was an out of balance wheel up front, had the tires rotated, but still vibrates. I suppose ALL the wheels could be out of balance, but seems unlikely?? Will have the balance checked on all wheels...

Golf V R32 :: Exhaust Has Nasty Rasp / Buzz On Acceleration

I have done the flapper mod. My exhaust has a nasty rasp on acceleration. I have a buddy with a MkIV R32 and his car sounds MUCH better than mine with no rasp.

Accord :: 88 LXi - Uneven Acceleration When RPM Is In Range Of About 2200 - 2800

The car accelerates unevenly when the rpm is in the range of about 2200 - 2800 rpm. Above that engine speed, it quickly smooths out. I replaced the distributor in it in Jan. 2010 and I'm wondering whether the distributor and/or vacuum advance is the cause of this behavior. I don't know whether the distributor also has a centrifugal advance. If it does, then I guess that could another possible cause.

Could I test the vacuum advance by disconnecting the 2 vacuum lines from the vacuum advance control? How to troubleshoot this behavior?

The distributor was bundled with the vacuum advance control, so I presume I'd be replacing the whole assembly if I can verify that the distributor or vacuum advance control is the problem.

Toyota - Camry :: 2003 - Hiccups On Acceleration At 2800 RPM When It Is Hot Outside

The particulars are 2003 Camry, 4 cyl, manual trans. When it gets to be 90 degrees or hotter outside, the car hiccups when accelerating through 2800 rpm. That is the most common scenario. Pretty much any gear and the problem gets worse the hotter to outside air. It never throws a code or check engine light. It doesn't stall although it feels like an instantaneous loss of ignition. I can set the cruise control and it will periodically happen when driving through the desert. It repeats as often as it wants to....no overall pattern, uphill or flat, no difference. Dealer says nothing is wrong since it won't throw a code. No issue in the winter, only hot summer driving.

Ford F-150 (2004-2008) :: Odd Misfire Between 1k And 2k RPM Under Only Moderate Acceleration

So, my 2004 with its constant tick is now "Missing", but only under moderate acceleration, between 1k and 2k rpms. i.e., : When in OD and wanting to gain a few MPH, but not drop down a gear. I have noticed it in OD and in 3rd. Feels like the engine stops for a split second, several times.

Camry :: 2007 SE V6 - Noise Heard Under Moderate To Hard Acceleration

I have a 2007 Camry SE V6. Under moderate to hard acceleration, it sounds like a deep throaty sound coming from where the intake/throttle body is located, almost as if I have a SRI, but I do not. I checked for anything loose, hoses, airbox, etc. Then checked the intake resonator below and to the left of the battery, all seemed normal. Everything seems normal! Only happens when I push the accelerator a little more than usual, for example, when I go on the highway.

Prius (2010-12) :: Brake Loose The Tyres With Moderate Acceleration

My 2010 III, not 3 or Three since it is a 2010, will brake loose the tires when wet with moderate acceleration. If i floor it it will alternate spinning right to left until I back off the throttle. I"m not really complaining since I had an 08 that would not spin a tire and could not be driven in snow. Just wondering if this is normal on a 2010.

I turned right with moderate acceleration on wet pavement today and the tyres broke loose and the car was headed for the curb. Oh the traction control light does come on when this happens but, no brake application or engine speed reduction.

Touareg :: 2004 V8 - Clatter Noise Under Moderate To Hard Acceleration

I have an 04 V8 and have consistently noted a valve(?) clatter noise under moderate to hard acceleration. I mentioned it to my VW sales associate and he stated this is typical of this engine and that after warm up it should no longer occur. I hear the clatter at any time, warm or cold.

Touareg :: V8 Transmission Lurching Forward On Upshifts Under Moderate Acceleration

I've been told by my dealer that the 6-speed transmission in our rigs is known to shift roughly. They have therefore pronounced my truck healthy. However, I don't think I believe it. I've never seen a vehicle that lurched forward on upshifts under moderate acceleration. It behaves if I punch it. It behaves if I accelerate like my granny. Anything in between and I get a fairly violent jump at each shift point. At times, in stop-and-go traffice, I have thought the truck would jump into the car ahead of me. This behavior seems to be unrelated to which transmission mode I'm in. D, S, and Tip all do it. I love the motor in this thing, but I'm starting to hate the tranny. What should I tell the dealer to look for on the truck that might be causing this? The truck is going in next week to replace a fog light with condensation, so I'm hoping to get them to look at it then.

Honda - Cr-v :: 2000 - Thumping Noise Coming Through Floorboard Under Moderate Acceleration

I am original owner of a 2000 CRV, it's in really good shape and has been maintained by me on about 99% of all repairs it has 140k total. I have this thumping noise coming through the floorboard by my feet, under moderate acceleration and it goes away at just about any speed when you quit accelerating. Sounded like a bad halfshaft, I had already replaced one so I did the other side, got worse. So I replaced the one that had been in for just 2 years--no better. Asked the auto parts store for a recommendation and went to that shop, they balanced the tires, checked rotors and concluded I was buying junky rebuild half shafts. I had them replace the one they thought was bad with another rebuild, just as bad or worse...

I took home and put in both sides with new halfshafts, I also noticed some play in jackshaft bearing and replaced that as well....no better. Shop claims that a website they subscribe to says that 50% of aftermarket halfshafts for CRV are no good. But honestly we are 5 for 5 bad, last two were new from NAPA. Pulled things apart and checked wheel bearings left side was sticky so had machine shop press one into the knuckle, right side was done about 14 months ago. Also disconnected drive line and drove it as a 2 wheel drive vehicle....no better. Would a broken tire belt only make noise on acceleration or after a corner when you accelerate? Is this a possible indication of my transaxle going out? ---

Ford F-150 (2009-2014) :: Hesitation With Moderate Acceleration And Felt Mostly In 3rd Gear

I have an 09 F150 4x4 with 116,000 miles on the clock. I am having an issue with moderate acceleration and felt mostly in 3rd gear. I changed the spark plugs at 106,000 miles with OEM replacements. I have had this issue since about 80,000 miles but intermittently. It seems its starting to get worse as time goes by. The problem is both cold or warm and doesn't happen all the time but now about 80%. Light acceleration is good and full acceleration is great with no issues.

Feels more like running out of fuel but not to the point of stumbling. Possible misfire that is not being detected. No check engine light lit. Tranny shifts perfect. Idles extremely smooth. I was thinking a coil problem but with no engine light, I don't want to try to guess which one. So far, this truck has been awesome and has needed nothing but tires and routine maintenance. I pull trailers consistently and this beast is not abused nor babied.

Tiguan :: Turbo System - Power / Boost Pulse When Under Moderate To Heavy Acceleration

I am experiencing a power/boost pulse when under moderate to heavy acceleration. I'm wondering if this is a sign of my diverter valve failing or another issue withing the turbo system.

I don't have a boost gauge and the main pulsing seems to be between 2800 and 5k in the rpm band.

Ford 6.7L Power Stroke Diesel :: Turbo Boost Will Jump To 10 PSI At Moderate Acceleration

I'm relatively new to the 6.7 engine , I have a 2014 F-350 SRW with aprox 51,000 miles on it. Normal driving I see about 8 to 10 psi of boost even under moderate acceleration although at times it will go to about 18 psi at WOT and it does this with heavy loads. At moderate acceleration the boost will jump to 10 psi quickly but immediately stop there and sometimes as the RPM"s increase boost pressure decreases. Only issues I have had with the truck was a clogged EGR cooler.
