Phaeton :: 2008 - Turbo Charger Whistle From 1500 -1800 RPM

Noticed yesterday a slight whistle from turbo in my 108,000 mile MY2008 3.0tdi ( the engine is new at 90k miles, but the turbo was transferred over).

Its barely audible, a gentle whistle from about 1500 to 1800 rpm on moderate acceleration. It's then lost in general engine/ road noise. Car drives smoothly and pulls as normal.

Only noticeable on quite road surfaces, radio off, etc, and no more than I recall as standard from earlier turbo diesel Audi & BMW cars from the 1990's.

A quick on-line search indicates carbon build-up can be an issue? In the past few years my mileage has dropped way down to maybe 9k miles per year, mostly shorter trips & not as much higher speed motorway as previously.

If this is the potential end in sight for the turbo, can the unit be refurbished.

Ford - F150 :: 2005 - Whistle / Howl Sound At Certain Speeds

I have 140,000 miles on my 2005 F-150 and for the past year I have noticed a somewhat high-pitch whistle or howling sound coming from either the front or underneath. The pitch and volume continuously varies as though it is just tire howl, but I just changed all four tires and no results. It gets much louder at about 65 mph and 78 mph, but I don't hardly hear it at any other speed. My brother says it's just a wind whistle, but I strongly disagree as it doesn't change when i drive against or with a strong wind. I rely on this pickup for work and can't afford to be without it for more than a day or two, so, for peace of mind at least, I would like to know what is making the sound.

Subaru - Outback :: 2005 - Whistle Or Whining Noise Periodically

In the last couple of weeks I've been getting a whistle or whining noise I think from under my car periodically. It doesn't happen when I start the car, not when idling and starts at about 20/30 mph. I've had the car in the shop for regular maintenance, just replaced front bushings, put on new rear brake pads and new rotors. I've checked the car for anything that might cause wind since it comes and goes even while driving. Seems worse in hot, damp weather. Back to the dealer today because it was loud and they say drive shaft, but there is no vibration and the car is running very smoothly. It's driving me crazy when it happens because it almost sounds like a plane landing.

Lexus GX 2004-09 :: 2005 - Bizarre Whistle Noise From Front Right Wheel?

I have a 2005 Lexus is 200, but I'm not sure if the model even matters for my question.

Anyway, I'm hearing a strange whistle from the front right wheel, and I'm sure the sound comes from it. I made a youtube video so you can get the idea.

The sound starts at around 50km/h speed and it does not change after that, meaning that it doesn't become harder if I speed up and if I slow down to 40 or 20 it does not go away. But if the car is cold, it does not start until I reach 50-60km/h speed.

Also, I tried turning the engine off on neutral while driving and it did not influence the noise in anyway. So its not related to motor.

In the video it starts from 11s and you can hear it clearly starting at 57s when I speed up. Because of other sounds you probably can not hear it as clear as I can, but just listen to the whole video and I think you will get a clear idea.

Here is the video: [URL] ....

The thing is, I went to a decent repair garage and they could not say what it is. So assume that basic things like breaks or the like were checked by mechanics.

I want to add that there probably was a hard hit to the right wheel recently while driving in reverse, I say "probably" because the person did it does not want to admit it and I can only guess, so I dont have an idea how it went. But I found a deep slicing (not sure if its the right word) on the right wheel tire and it was so deep (and around 5cm in width) that I had to replace the tire. So assume that there could have been a hard hit and the wheel took damage. The noise started a couple of the days after I found it.

Phaeton :: Temperature Control For Center Air Vents

How are you supposed to use this switch? (the switch below the clock) I'm also confused how this switch affects the overall pre-set temperature. Is this switch supposed to allow the air conditioning system in the center vents to get colder than the other vents? If so, how can that happen?

Phaeton :: A/C Malfunction - No Air From Vents - Thermostat Went Up To 126 Degrees

I was driving for work in the Coachella Valley (Palm Springs) today - it was 109 degrees. I hop in the car after a work visit, the vent covers open, but nothing comes out. The fan is blowing full blast - but no air was coming out of any vents. I tried manual mode, foot, defrost, off, etc. to no effect. I reset the climate system, reset all, no dice. Soon, the fan turned off, paused a couple seconds, then turned back on again and tried again to the safe effect. I turned off the ignition and turned it back on. Nothing. Drove to my next stop and parked. I came out, started up again - this time air comes out of the vents, but it's hot.

I took the car to the nearest VW dealer, and the foreman came out with his diagnostic tool (the big one - not the VAG-COM) and told me their were 23 faults with the air conditioning system.

One other interesting thing - my thermometer was going nuts at the same time. It was 109, but the thermometer quickly went up to 126 degrees within a few minutes - the engine temperature went up or got hot.

The good (?) news is I don't think this would have been covered under warranty, because their aren't any broken parts - just needs a recharge...at least that's what it looks like now.

The early diagnosis is that I need an A/C recharge, and if the refrigerant gets even a little low, the entire system shuts off.

Ford - Freestar :: 2005 - High Pitched Whistle In Front End During Highway Driving

My 2005 Ford Freestar with 164k miles experiences a high pitched whistling noise coming from the front end after a few minutes of highway speed driving. It sounds like a tea kettle whistle. It starts out as a quick pulsed whistle then moves to a solid whistling noise. I've heard it driving straight and turning. The sound pulsates if I turn the steering wheel slightly to the left or right but seems to occur more when I turn right. The sound does not occur if van is not in motion and will stop just before car comes to rest at a stop. Three repair shops have looked at this and none of them can replicate the sound while van is on a lift but one shop did hear it during a test drive. All three shops have been unable to locate / diagnose this whistling noise. They all state brakes are in very good shape.

Malibu :: 2005 - Intermittent Low Pitch Whistle Noise When Turning Sharply On Right Turns

2005 Malibu LS 3.5L (Epsilon Body) with rear disk brakes. Do the rear disk brake pads have the wear indicators just like the front pads?

Car started making an intermittent low pitch whistle noise (sounds like an old steam locomotive whistle, just really low muffled) but it only does it while turning sharply on right turns. It doesn't come on while turning left or driving straight.

At first I suspected the fuel pump but I'm not sure. I've owned the car since 2008 and never replaced the rear brakes, so it might be time!

Phaeton :: Driver Side Air Vents Started Blowing Non - Cooled Air

I plan on taking my (new to me) 2004 V8 Phaeton in for some CPO work - already.. A couple days ago all my Driver Side air vents (front, back, even ventilated seat) started blowing non-cooled air while the passenger side seemed to be working fine. You can literally stick your hand up and feel the difference between the left and right side of the clock.

The question is, are there 2 compressors - one for the left and one for the right? or is this some weird fuse that has blown and only affected the driver's side? The fan functions just the same - just not cooling the air on the driver's side. I have all the zones connected together and at the lowest setting for the test.

Phaeton :: 2004 - Mildly Cool Air Coming Out Of Driver Side Vents

Had a few warm days last week and noticed a lack of cooling from the HVAC system. Local temps cooled off a bit but I decided to see what I could find out before I got hot again.

Started playing with the system in the driveway and discovered good cooling capacity on the passenger side but just mildly cool air coming out of the drivers side vents. This seemed to be true on both the front and back. I hooked by laptop up and noticed single digit temps at the evaporator. When I brought the temps down on the climate control the right side exchanger would get down to around 12C but the Left would struggle to get to 22C and if I moved the passenger side requested temp up the drivers side exchanger temp would follow even though the requested temp on the drivers side was low. There was a display for the Left and Right regulating valves but they seemed parked at 0.0 unless I made a cabin temp change.

I am guessing the left regulating valve is the problem but know nothing of how this system works. 2004 Phaeton V8 ....

Phaeton :: AC Shut Down / Air Flow Remained Constant Except Temp From All Vents Went Tropical

Yesterday the temp was at 97F and the air conditioning shut down (air flow remained constant except temp from all vents went tropical). The car was moving at 70mph on level ground in light traffic and not in a city. Stopped and ran a few 'reboot cycles' (turning ignition on and off in three minute intervals with the key out of range) with no luck. The next day the air worked OK - not great - but it was working and the problem returned after one hour of operation. Am I describing a refrigerant level problem or are the electron gods just angry at me for driving in a heat wave?

Prius (2004-09) :: 2005 - No Heat From Vents?

I recently picked up a 2005 Prius with 129k miles that seems to be in gFor any codes.

With most cars this would usually point to a faulty thermostat but I'm not sure on a Prius. I checked the coolant level and it's fine. I don't hear any gurgling in the dash so I'm guessing there's no air in the system.

Ford A/C :: 2005 F250 - No Air Flow Comes From The Vents

I have a 2005 F250 with an intermittent AC problem. I had noticed over the past year that I only had high or low fan when adjusting my AC. Recently my AC has intermittently just not started blowing any air when I turn it on. When this occurs, I can put the fan on high and hear the clutch engage, however no air flow comes from the vents. I did some searching around and didn't find an answer. I was curious, where I might be best to start troubleshooting.

Prius (2004-09) :: 2005 - AC Blowing Hot / Not Cold And Some Kind Of Smoke Out Of The Vents

My problems in my ac begin last year around Summer. My ac was blowing hot and not cold and once it even blew some kind of smoke out of the vents. It only did that once and hasn't since. I went to good year and put some freon in the car. And it started to blow cold again and I was good for a while. Well I didn't need the cold air for the last few months till the heat started up again.

Ford 6.0L Power Stroke Diesel :: 2005 - EATC - No Air Out Of Dash Vents

My buddy's '05 will not blow out of the dash vents, you can make the a/c blow out the defrost or the floor but no dash. Vacuum pump is working great, rarely ever kicks on and doesn't seem to be leaking anywhere in the system that I can tell yet. Pulling a vacuum on the red line will make it start blowing out the vents so the door is functioning.

I thought maybe I had narrowed it down to the ATC solenoid and manifold (Ford part #5c3z-19d611-aa) not working properly but found that the F-150 guys having problems with the o-rings on the back of the control head. Seems they replace the 4 o-rings and all is well, cheap easy fix. Are the units on the diesel set up that way too?

A quick search for EATC problems on the diesels didn't bring up much, seems they don't tend to fail. He's wanting to sell it and asked if I could try and fix the problem. It's been about a year since I last looked at it, so my recollection might be a bit foggy.
