Passat (B6) :: Front End Vibration During Initial Cold Startups
Nov 18, 2010
Just recently I've noticed my front end on my B6 3.6 4mo vibrates during the initial start-up in the morning. After the car warms up the vibrations go away. I had new brakes, oil change and tire rotated recently. I checked the cold start air pressure on the wheels (Nexen 235-40-18) and they are at 38 PSI, cold. All tires still have their balance weights also. I can feel the vibration in the steering wheel and seat. This vibration only started after I had the mentioned work done on my car.

I just replaced two bad sensors, (bank 2, both sensors). I went through three cold start ups, and the autozone codes still claim the sensors are rubbish.

Currently working on a friends 2011 Prius with roughly ~340,000 miles (!!!!!) that was used as a taxi, until now, he bought it from the taxi company and converted it his own daily.
I did a regular oil change on his Prius, and decided to change the spark plugs as at the time there was some sort of occasional shaking/rattle at cold startups. The shaking was gone after changing the spark plugs. This was all done back in March. Yesterday, he was driving, and all of a sudden, the knocking came back, a check engine light, and white like cloud smoke appear. Check Engine lights were P0300, P0301, P0303 (misfire cylinder). I told him to bring it over, I took a look, and his invertor engine coolant was all the way down (he told me he filled it up to top just two weeks ago). I originally thought maybe it was the ignition coils (for shaking), but the white smoke didn't make sense. So I purposely filled the coolant above the full line, and took it out to drive for about half a mile, and just as I suspected when I opened the hood, the coolant level decreased, at least by an inch.
I did not see any oil leaks, and the oil levels were just fine. The car just seems to shake/rattle at startup and when accelerating at low speeds (roughly 8 - 15 MPH) and than goes away, and drives normally. It still does blow off that white/cloud smoke when accelerating hard on the engine though. As for the smell of the smoke, I can't really tell, it is definitely not sweet, but it kind of smells foul/bad.
At this point, I am pretty sure this engine is gone, and the gasket/seal is blown.

I have a 2006 Camry 2.4l and I'm hearing a loud noise coming from the idler pulley on cold startups when I put it in gear. I don't hear it when it's in park. The noise gets worse if you turn the a/c on. I have replaced the belt, idler pulley and top motor mount. I took the belt off and cranked it when cold and there was no noise even in gear. I can see the idler pulley moving and can confirm that's the noise but what it causing the belt to make it do that? Could I have bought a defective idler pulley?

From time to time I get this high vibration on start-up of the car. It almost seems like more of the engine noise and vibration is coming through to the cabin. It only lasts about 5 seconds from initial start up and the rpm does not change and stays constant. This only happens maybe once every other week or once a month. What or why this could be happening?

What causes elevated engine idle when cold or initial startup? Asking another way, what would cause it not to have the elevated idle on start up?

Okay, so I'm now up to 154,000 miles on my '08. Not doing too bad replacing the the intercooler, starter, rear brakes (3rd set), rotors, front brakes (1st set at 135k ) and some other regular maintenance over the last 30k or so. Started getting some vibration under the front between 15 and 35 mph a couple of months ago. Felt a little slop in the cv area so I replaced the axles. Still getting the vibration, moreso when it's cold than warmed up. Put it up on the rack and feel some serious slop on the passenger side where the shaft enters the trans. I think the bearing in the trans might be the culprit. I'm struggling finding information on pulling the trans and doing a rebuild or even general parts replacements.

I have a vibration coming from what seems to be the right front of the car when I exceed 50mph. It doesn't matter what type of road it is (concrete vs. asphalt) and it doesn't go away.
The vibration has a pattern to it, the best I can describe it is a cycle (wrrr----wrrr----wrr). My wheels are 18s with OEM Pirellis, car is a 3.6l sport wagon. I have never owned a car with this brand so I cannot rule out the tire. Naturally the dealer hears the noise but they say nothing is wrong with the car.
What I can do to make it go away. This noise distracts me form the rattles the dash, hatch and pillar make.

Brakes are too agressive on the Passat 3.6L 4Motion? Seems like the initial application, especially at slower speeds is too jerky. You have to be very soft on the pedal so as to not get your passengers hit the dash...
While you do want brakes that grab, I think that the modulation needed is beyond most drivers talent in order to execute a smooth stop without jerking.
I track my other car, so I'm familiar with brake modulation and race pads but again for a normal driver, this does not seem normal. The Audi A6 Bi-turbo is much smoother.

I have a 2006 VW Passat 2.0T with around 60,600 miles on it. Recently I had the CV axles replaced. Since then the front end vibrates whenever I accelerate. I took it to back to the mechanic and he said the engine mounts needed replaced. I am very skeptical of this diagnosis but am now stumped. (Also I had the tires balanced and rotated after the axles where replaced and the vibration is still there).

This just started happening on the driver side. Going over bumps and slight road wobble type imperfections make a medium pitched clunk sound. The sound stops as soon as I press the brakes ( which I just replaced last week). I do have a worn out bushing on the curved lower control arm. Could that be it? Do I need to replace all control arms or can I do just the curved set? If thats the issue.

I recently I had the cv boots replaced on my 2006 VW Passat 2.0. Since then the front vibrates upon acceleration. I have taken the car to a different mechanic than the one who did the cv boots and he says there may be a broken motor mount. I am skeptical about this diagnosis but now am completely stumped.

My 08 passat seems to shutter or vibrate at higher and lower speeds. It comes from the wheels(front). At first I thought my wheels aren't balanced, but the VW dealership said everything is fine.???huh.. they roadtested it and nothing...but others that drive with me totally notice it..Major road noise because of it.
They also sold me winter tires and rims and they wore out after 25k same noise?... "Broken beads".... they said i hit a pot hole.. I don't think so.... So what do you think? Rotors? if so how much am i gonna get jacked ..

Yesterday, I went to pick my car up from getting an oil change (full synthetic, Mobil 1 5w-30) and an estimate on brakes. turned out to not be quite as much as i had anticipated. while i was in making an appointment for the brake job, my mechanic and i were joking about how if it's not one thing, its another on VW's. And how the car will be in great shape after i get the brakes fixed/replaced.
So i go outside to drive home. When i start the car, there is this odd squeaking/vibration sound coming from the front of the engine. I immediately shut it down and go get the mechanic. after 30 minutes of muddling over it, we determine that it cannot be determined from just looking at it. so they're going to check it out on wednesday when it goes in for brakes.
A little more info, it is definitely something to do with the serpentine belt, because the sound is definately coming from the drivers side front of the engine. If you listen near the timing belt cover there is no sound so i'm pretty sure its not that. and the car drives fine, besides the weird noises that make it sound like a diesel at idle.
its a 2002 1.8t 5 speed wagon, 143,000 miles. I know 5w-30 mobil 1 is not 502 certified.

I recently had my front right boot replaced due to a hole. After being replaced there was a vibration in the front right part of the car (same place as where the boot was replaced.) Now I brought the car back to the shop where the boot was replaced, and they told me this vibration was caused by a bad wheel bearing in that section. After the shop replaced this bad wheel bearing, the problem still existed. Now this vibration happens only when I accelerate to 3300-3500RPM, and occurs at times when I make turns. What this might be or how this is caused?

I have a 2001 b5.5 passat sedan i recently picked up for cheap. The car was on cut springs and blown struts. I just installed JOM blue Line coilovers on it to solve the suspension problem. While i was doing this i realized both the cv boots were torn and needed replacing. I replaced the axles. The passat is a 1.8t with tip tronic trans. After i did the axles when i put the car in drive and let it idle i get a fairly noticeable vibration through out the car. It does not happen while driving or while in neutral. This did not happen before i did the axles. It doesnt make much sense to me?

I have what feels like a rotational vibration (front to back) during mid to hard acceleration in 5th gear (60-65+mph) and its driving me crazy trying to figure this out. I can slightly feel it under hard acceleration in 3rd gear as well.
I have tried two different sets of wheels (both after market and stock) with no luck. I am starting to think it is in the motor and not the suspension... Or could it be the trans? What can I check/inspect to get how to tackle this?
Info on the car: 2003 Wagon 1.8T 5sp. 40k miles

I recently replaced the brakes on my '99 Passat with all new rotors and pads. I used Mintex pads in front, as recommended by Adirondack Auto Brokers, and after a couple thousand miles, they are all broken in. The car stops fine and the pedal feels good, but there is always a groaning/vibration/creaking right at the very end of the stop. Nothing unsafe or a problem, but just annoying. It is only when the car comes to a complete stop at the last 6 inches of motion. If I let the brake pedal up slowly from a stop, it will also do it. What can I do to get rid of this, or is it from the pads and I just have to live with it until they are replaced?

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!

I just bought a 2007 2.0T Passat with 25,000 miles. It makes a lot of noice going over bumbs or when front end dives especially when it's cold. Is this a well known topic?

I've got a 2006 b6 2.0 with about 92k on it. I bought it Cpo at around 68k 3 years ago this December. My auto tech said I'm going to need a new timing belt in about a month, so once this semester is over in a few weeks I'll be taking it in for that. Anyway, to my questions. My front suspension squeeks quite a bit going over bumps, especially when cold. Is this a sign of bad things to come in the future? Now my brakes, when they get wet they give off a very rough feeling, not very smooth. I have to slam on my brakes to 'wake them up'. Is this telling me they need to be replaced?
