Phaeton :: Slight Cyclic Vibration / Pedal Pressure On Braking
Jan 19, 2011
I had the discs replaced by VW UK & my VW garage a few months ago (V6 TDI) , car was close to 3 years and ~50K miles. There was a slight cyclic vibration/ pedal pressure on braking, not easy to detect, but from once you knew it was there it was annoying. I was not convinced the replacement was 100% successful, but it was not until I had 4 new tyres fitted and all rebalanced last week that I could clearly see that I still have the problem, maybe even worse than before the discs were replaced.

-Is there anything else that can cause the same brake pedal feel, other than a warped disc: a bend in a suspension component or the like? I query this as I bent an wheel last year in a huge pothole and wondered if this could have damaged something
-I have found a local company with an on-wheel disc skimming machine that I understand can be excellent to resolve these issues. Maybe this would be the way to go.

I have only done 15000 motorway miles in my 2009 V6 TDI and seem to have a slight juddering feeling when braking. I am sure it did it for a day so a few months ago and disappeared - issue reappeared today. Wonder if it is warped discs? Car has been stood for 2 weeks.
Braking is fine and efficient it is as though you have that shuddering you get when ABS cuts in. Drove 500 miles this weekend and problem still there.

Ever since I took my 18" wheels off for the winter and put the stock VW 16's with snow tires I have on multiple occasions almost rear ended the car in front of me when I experienced what seemed like a loss of brake pressure. The brake pedal did not feel spongy or anything but often in this situation the abs brakes seem to kick in for no reason. I feel a slight pulsation in the brake pedal which I can only assume is an activation of abs. I'm wondering if this slight pulsation (1 second duration ) is causing my brakes to be less effective. The pavement has been completely dry and I was not traveling fast enough, nor pressing the brakes hard enough to cause the tires to lock and trip the abs.

Driving along last night and suddenly slightly oily smell in cabin. Then notice oil pressure drops from normal 82 ish to about 25. Recovers to about 70 by time I get to Waitrose (about ten mins). Park up and do shopping. Move car and check for oil patch - none found. Drive home and pressure still lower than usual - but recovers to just under normal. No warning lights - open oil filler cap and seems to be some in there. No oil leak found.

It took me a while to realize it, but my Phaeton vibrates as it rolls. My wife and friend only noticed it when I called their attention to it, but I've come to pick up on it every time I drive the car, as shortly as a few blocks away from home, from about 30 MPH and upwards.
How do I know? Well, we have two other cars, including a Touareg and a smart, and those two sure do not vibrate the way the Phaeton does! My wife and I just pick up whatever car, so I am likely to drive two or three cars on any given week. I've tried to ignore it, but to me, every time I pick up the Phaeton, it is very bothersome to me.
I've put new tires on the car, had them "force balanced", the computer scores came out great, and the alignment technician at the VW dealership said he can't feel the car vibrate while we rode together. The rims are good and straight. But it clearly does vibrate.
By the way, the front suspension shudders very un-German-like in potholes. I speculate it is related. But I am dreading taking the car to the VW dealer service technician and have him come back that the car is fine.

I have a slight vibration coming at speeds of 80kph and up that is driving me crazy. The steering wheel doesn"t shake so I am leaning more towards a rear of car issue. The center driveshaft and transmission were replaced and new tires{Conti Extreme Contact DW} Wheels are not bent. The car has 130,000 km"s. The vibe happens mostly when accelerating up freeway ramps. Once the car settles at highway speeds{100_120kph} it tends to reduce to a constant faint shake that you feel in the seats. Rear wheel bearings? CV joints? I am the only one who feels the shaking because I know how smooth a ride it used to be.

My 2010 RX 350 only has 35K miles and I've been feeling that the smoothness in the ride has really deteriorated in the last several months. So much so, that even though I could have squeezed another 5K or so out of my tires, I bought a new set...OEM Michelin Latitude Tour HP. I can't say the ride has improved at all. Today, I brought it to the Lexus dealer for a brake inspection, because I was getting a slight vibration in the wheel when braking. Front brake job was needed. I was given a 2013 RX 350 as a loaner. The ride in that car is so much smoother. Should I be questioning the suspension or some other issue that would improve the ride?

I have a 2011 RX350 and like car for the most part. Something strange I have noticed is that the gas pedal seams to have some little vibration when I am pressing it smoothly. My foot is constant on the gas pedal maybe 1/4 of the way down and it doesn't feel smooth like other vehicles. I have a 2014 lex IS250 and it doesn't have that vibration. Also had a 2004 RX330 and it did not have that vibration. It is a slight vibration that ruins the luxury driving experience.

I have a NEW (purchased May 18th) 2012 Honda Accord. After starting the car there is a small vibration at 16-18 mph which I feel slightly in the gas pedal. A week ago, it started making a slight click when the car reaches 30 mph. This happens only when the first time it reaches these speeds when the car is started. Once started, I can stop and start (without turning off the car) as many times as I need without the sound. However, if I turn the car off and back on, the sounds happens again.

Just bought this van used last fall. Had an occasion, a few months ago, to brake quite hard (to avoid hitting a bird in the road--yeah, I know...) and felt a clattering vibration/noise in my brake pedal. It's happened a few times since then. Is this a problem that needs to be looked at or a normal reaction to quick, hard braking? (Braking noise in 2008 Dodge Grand Caravan)

A couple weeks ago I started experiencing some issues with what seems to be the ABS: when braking to a full stop, a "motor" sound appeared accompanied by vibration on the pedal; however, the ABS indicator light did not light on (although it does light on when I start the car). Several weeks later I began having problems with the transmission. It first appeared when putting the vehicle in reverse but now it happens in almost all gears. Finally, the "service engine soon" light turned on.
I took my car to the mechanic and he said the problem is a solenoid and quote a repair (includes valve body replacement and work). He claimed that the "ABS problem" is related to the transmission issue but as I explained above the "ABS problem" predated the transmission issue. My question is, does this link between ABS and transmission make sense? Also, if I go ahead and replace the transmission valve body can I be confident that I won't have any more issues with the transmission for a while? I am concern about spending more on this car giving its current trade value (I already replaced the front suspension struts, brake pads and rotor discs and new tires).

To all 2014 and 2015 GX 460 owners, does brake pedal have a slight modulation or vibration while press it. Feels like ABS but not as strong pumping action.
When I step on the brakes the first time feels normal and then I let go of the brakes, then I press it the second time that is when I feel a slight modulation or vibration of the brake pedal.

Has intermittent buzzing sensation through both the brake pedal and accelerator when at low speed or stationary? I drive a v10 diesel. I am aware of the normal vibration associated with a diesel (which is near non-existent in the Phaeton) but this is something very different.

I am experiencing a slight rumble-strip-like vibration/noise when veering to the right. There is no noticeable vibration when driving straight or to the right - sounds like it's coming from the front. I thought it was my tires but had them rotated with same symptoms/ I first noticed this shortly after I had them rotated in July. So it's probably front suspension.

I hit a pot hole. Front left tire went flat and wheel damaged. I changed tired and wheel. After that humming or cyclic roaring sound is coming from front of car when speed goes above 30mph. Front middle or front-right side I can't really say for sure exactly from where it is coming but it is front. What it could be. It's not bad so far. I can still drive at 65mph.

On startup my 2005 Prius standard produces a low level cyclic noise which sounds like a hacksaw. This noise lasts for several minutes and is not affected by putting the car in motion or leaving it parked. The noise seems to be coming from the Synergy Unit but who knows?

I have started to hear a slight (but getting louder) squeal from my brakes when I am braking from moderate speeds (20 mph and under). I know that the car had new stock brakes put on it less than a year ago. What I should do about it?
Stock 1.8T 5spd 2001 discs all around.

Picked up my MK6 GTI DSG last Saturday. I have noticed a slight shudder when braking and coming to a gentle stop. At first I thought it may be the brakes bedding in so I kept it over the weekend. By today there's still no change. Is it normal for DSG transmission stop like this? Because I have never driven DSG transmission.

In the morning when I back down the driveway with slight braking, the brakes make a loud hollow squeaky sound in a tunnel. The rear brakes were changed about 2 months ago.

Braking down a hill and a sharp turn (in either direction) around 10mph results in a slight knock (1, not multiple). Is it normal? I have some suspension goodies to put on but i don't want to do that before getting any repairs done if necessary...

My Treg has about 3K miles on it right now, and since I picked it up, the brakes have squealed (some times VERY loud, some times just a slight squeak at the end of the braking process). It is currently in the shop for the second time to get a fix for this or an adjustment, and I just got a call from my service advisor telling me there is nothing they can do to quiet the brakes--it is the nature of brakes to squeak and squeal.
I realize that brake dust (and man, there is a lot of that on this vehicle) can make the brakes squeal a bit, but does it even make sense that they would tell me that brakes are supposed to squeal?
I am also having a sticking door handle and a defective ac/heat control issue looked at while the Treg is in (I can illuminate both the "auto" and "econ" buttons at the same time, instead of one switching the other off). Should a vehicle at this price point have noisy brakes?
