Phaeton :: 2005 - Peculiar Humming Noise When Car Is Running
Jul 17, 2009
My father and I have an '05 W12 Phaeton with 54k miles. It's developed a peculiar humming noise (very harmonic like a resonance) that is present any time the car is running. My father insists on taking the car to an independent European car repair facility instead of the dealership (much to my displeasure).
The shop first said it was transmission related and advised a fluid change. This did nothing to fix the issue and I'm not even confident that they have the ability to do such a thing correctly without dealer specific tools. Car never left the shop as that obviously did nothing.
Next, they claim there resonance was felt / heard through an oil line. They changed oil and filter thinking bad oil filter (crazy, I know). This also did nothing.
Now, they say that they attempted bypassing the oil cooler and this made the noise go away. The are advising replacement of the oil cooler assembly.

I Get a humming noise in all my speakers if I have my DTR lights on... Fog lamps don't matter, head lamps don't matter, just the day time running lights make it hum. If I have the lights set to "auto" and it's day time it hums, and if I switch it to day lights it keeps humming. But if I turn on the headlights (day light turns off) or if I turn the headlights off, the humming stops both ways. Fog lamps don't matter at all either. Why I'm getting humming with just the day time running lights??

I have a humming noise coming from the front end of my 2004 W12. I only notice the noise at highway speeds and it appears to only be audible when I turn the wheel to the right. For example, when traveling on the highway and the road bends slightly to the right or when I move into the right lane, I hear a faint hum coming from the wheel(s).
I started hearing the hum a few days ago but dismissed it as a symptom of my Phaeton Obsessive-Compulsive Disorder (POCD). While driving to and from DC last night on a night out with my wife, she commented on the presence of the hum as well.
I just had the LF wheel bearing replaced 2 weeks ago. Here are some possibilities I'v thought of:
RF wheel bearing
Low Power Steering Fuild
Other Steering Problems (leaking rack)
On a related note, where do you check the power steering fluid level? I can't seem to find the reservoir.

My 05 V8 Phaeton radiator cooling fan is not running and hence engine overheats. The AC cooling fan works alright, it comes on when i switch on the AC. I have verified that the actual radiator cooling fan works by plugging it to the ac cooling fan socket. I have checked fuses and all ok. there are no dealers near me. I have also gone through all the cooling fan threads and all of them are for constant running fans, none for a non running fan.

Our 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.

My Subaru started making a noise that the mechanic can't seem to identify - I hear it when the car is in gear and moving only - it's like a humming noise that increases in frequency as the car goes faster and winds down as I approach a stop - it totally stops if the car is not moving even though the engine is running. It doesn't sound like it's coming from the tires. It's a noise that I feel like I've heard coming from a K car or a Chrysler or something. It's not a rattling but rather changes regularly with acceleration/deceleration. I was thinking it might have something to do with the turbo. The car seems a little sluggish (more than lag in the turbo, maybe?)

I have a 2005 Cadillac CTS with 23k miles. It was my grandmothers car and is in excellent shape. It has had regular service and has had no mechanical problems. I have noticed recently that there is a humming noise that corresponds with the rotation of the tires. It seems to be coming from the left side and is almost unnoticeable at slow speeds but around 55-60 mph it is very noticeable. I had the wheels rotated with the last oil change and it seemed to stay the same, although the left rear tire is now on the left front. That tire loses pressure and I check it weekly. It's always a few pounds low. Could a bad tire be the cause of the noise? There is no vibration in the steering wheel and it doesn't get louder when I turn the wheel to one side of the other like a wheel bearing might.

2005 Jetta. The car makes a loud deep humming noise once I hit about 75mph, and goes away once I get to about 82 or so. I've taken it out of gear and matched the rpm I get at those speeds, and I don't hear the noise at all. It's only when I'm in gear. What this could be?

My friend has a 2007 Avalon with 150,000 miles. He ran over a chunk of rubber tire that was in the road and now has a load noise at 40 to 60 mph. He believes that a sound deading material is missing from under the car. He took it to the dealer and they could not determine the cause. He also took it to a local repair shop and they could not fix it. It appears that this material is used in the wheel wells also.

Wife complained about the noise coming from the front. She said it sounds like an engine noise. I took her car for a few days noticed the noise starting at about 25mph+ (near the driver side). Tried to put the engine in N and rev it, while driving, pretty such it is not the engine.
I do notice the noise is getting a bit louder today compared to last week...Did some google search and "it might" be the bearing. Just wonder what to do next. My wife doesn't want to drive it at this time....so she took my truck today

I have a 2005 Hyundai Elantra that makes a RRrrrRRRrRRR noise when turning corners - only to the right. It's not a screeching or scraping noise... more of a loud whirring or humming. One note- back left tire was removed and repaired shortly before this began - could that relate?

I have a 97 Lumina sedan. When moderately accelerating between 50-60 on a slight incline, the car will sometimes start to "jolt" a little repeatedly. It continues to do it if I hold the pedal steady, but if the incline goes away or I press the gas pedal to accelerate harder the jolting will stop as abruptly as it started. The magic number seems to be around 55mph, never outside that range. I can reproduce it on certain interchange ramps or hills, but only in overdrive. Regular drive gear doesn't do it but the engine is at a much higher RPM. If I accelerate harder than I usually do it also doesn't seem to occur.
At first I thought it was just the same RPM loss issue at speed in a low cruising RPM, something that happens infrequently at idle. But now I'm worried the specificity might indicate a transmission problem. Car only has 87K miles on it for its age though.

My 05 phaeton has a lot of wind noise coming from it especially over 60 miles per hour. The window is fully up the door is closed and even in the car wash no water gets in. The seal seems tight.

It's starting to get a little chilly, and I'm hearing a strange noise. When the car is cold and the heater fan is on 3 or 4 "marks", I can hear a hum coming from behind the dash on the drivers side. The hum will have a haearbeat type sound to it every second or so. It's definitely some type of motor sound. It seems to go away (or maybe I can't hear it) when the car heats up.

I have noticed a loud humming sound coming from the truck when I have the AC on. Also you can feel the vibration as well. I turn off the AC and it goes away. All this happens on an infrequent behavior but does happen daily. what gives?

I am hearing a whining noise only after car has been running awhile and only when turning left. The noise seems to come from the back passenger side. What this could be?

I recently bought a 2005 Buick Century with 86,140 miles. It has a few things my old Century didn’t have including traction control, anti-lock brakes and 4-speed automatic overdrive. When I slow down to negotiate a sharp turn at an intersection, I sometimes hear a brief humming sound from the front end. It lasts for a second or two. It happens after the car’s been driven for about an hour. I don’t know if it’s the transmission, the brakes or power steering. It doesn’t matter if I turn right or left.

I just changed my front brakes in my 05 Ranger. New rotors, pads, bearings (packed), racers, new caliper on driver side, bleed all for brakes. Now when I am just about to stop it feels like the left front is grabbing. I also hear the ABS motor humming when it grabbs. Don't whats causing it?

Two things I have just noticed on my '09 with aprox. 120,000 miles.
Starting at about 45 mph, I am getting a humming noise
Doesn't get louder as speed goes up either, stays the same 45-75 mph
Have Bridgestone Ecopia EP422 tires, did rotation, noise did not change location
Noise does go away gradually when slowing down to a stop (after I have reached 45)
I am deaf on my left side, this is hard to tell where it is coming from
Second is this really odd brake pedal clink / pop noise. When brake pedal is depressed fully to the floor, car ON or OFF, there is a clunk
See attached links to the noise.....
Brake pads / rotors are like new, plenty of life on them. I did have the inverter pump replaced per the recall (I read somewhere this could be related?)

Car ON -

So i bought a 2005 Bentley continental gt and I have been told many times by different mechanics and owners that this car is almost like the VW Phaeton. Ever since i got the car, it had this problem so i don't know what caused it and how it can be fixed but basically all of my electronic components such as lights, windows, key fob remote, etc only work when the car's engine is actually turned on and running. As soon as i turn the engine off i hear a click in the trunk area and everything shuts off at the same time. It seems like some kind of safety cut off or something. It happens almost everytime and i have to close the doors manually with the key. Both batteries are brand new.

I have a 05 f250 diesel 6.0 with 173k. Between 35-60 mph it has started a humming sound and when the throttle is released the sound stops. I still have power boost etc. Someone mentioned degas cap, turbo pedestal or turbo pipes cracked.
