Phaeton :: 2008 - Turbo Charger Whistle From 1500 -1800 RPM
Oct 14, 2014
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.

When my Tig is cold, it seems to be very jerky or sluggish at 1500-1800rpm. There is definitely something happening at that range of RPM , almost seems like it's slipping and is jerky.
I know these 2.0's are notorious for the timing tensioner going (I have an 09) - could this be somehow related? I know that at a start I always get the famous rattle for a few seconds until oil pressure builds.

Experience a grinding noise at around 1500-1800 rpm when driving?
The noise sounds like the 2nd gen valve spring start up but not as loud.
The dealer was able to replicate the noise on my car but they don't know what is causing it.
They called the regional guy to come look at it but he doesn't have a clue where or what is causing the noise.

30k miles
Noise starts at around 10K-15k miles and dealer couldn't replicate it then but I hear it everyday.

I have a 01 7.3 F-350, 120000. I rarely get down hard on the go pedal but a while back I did and heard at pressure whistle just before it would shift. I thought a bad turbo hose so I replaced them all. 'While working on the hose mounts I cleaned up the castings for a better seal'. The hose replacement seemed to get the running but the whistle is still there. I am thinking a leak on the manifolds for the Y-Pipe connection OR does the turbo have a release valve that can make a whistle sound?

For a while now, I have been hearing a very high pitch whistle noise from the turbo/exhaust area. Everybody told me it was an exhaust leak, but I never could pin point the leak. While I was under the truck last weekend I found the flex joint on the passenger side up pipe was broken a leaking.
I ordered a Dorman replacement pipe that comes with a new gasket and hardware.
I will be the first to admit, I am not a fan of Dorman parts... BUT, this pipe is really nice. It looks identical to the pipe being sold on Dieselsite.com, it doesn't have the scoop inside to direct exhaust gas to the EGR cooler and it comes with all the mounting hardware.

Once I got the turbo down pipe out of the way and soaked the bolts with penetrating oil, I had the broken up pipe off in 30 minutes.

I have a 2002 f-250 7.3 diesel, i straight piped it but only by cutting muffler off and welding a piece of pipe in its place, it is pretty loud but id like to hear the turbo more like more of a whistle, it has a pretty good whistle once i get past 1500 rpm, is there a slightly bigger turbo i could put on without putting too much strain on the 180,000 mile engine?

My 2005 has developed a whistle with the fan on. Doesn't much change with dash vents open or closed but essentially comes on once I've turned the fan past 4 "bricks"....

My truck has 57k miles on it. At 1800-2100 RPM it whines under or over it is just fine. it has a new air filter in it as well, still makes the noise, it doesn't matter what gear i am in, it only does this under load. if i free rev it , it will not do it.

have been lurking the forum for the last several months ever since I bought my 2008 F150. I bought it used from a dealership and have had it at their shop no less than seven times since I bought it in March, all for the same things.
The first thing I noticed shortly after buying the truck was that after the truck warmed up it would idle rough. My chief complaint by far, I took the truck in to be looked at and this is when all the real fun began. Similarly I had intermittent power steering that I asked to have looked at.
I was told the fuel filter was completely clogged. They cleaned it and assured me all was well. They also bled the power steering system because apparently someone had changed the PS pump and not bled the system afterwards. I got into the truck to leave and it was idling no better than when I dropped it off. I complained again and was told that "this is just how this truck idles" and called BS. They offered to have the throttle body cleaned for me the next day to alleviate any remnants of rough idle.
Had the throttle body cleaned the next day and took the truck home. After about an hour or two I was still thoroughly dissatisfied with the idle and called back to complain. I forgot to mention that I bought my truck from a Chevrolet dealer who had just taken it in on trade about three days before I bought it. Because I complained they offered to send the truck to a Ford dealership for further diagnosis.
The Ford dealership found fouled plugs, a cracked intake manifold and the water pump and fan clutch both had excessive play. They said those would create a rocking sensation which could be misinterpreted as a rough idle. Over $2500 the Chevy dealership paid them and I was called to come pick up the truck.
I didn't even make it out of the parking lot because the truck was whining something fierce. I couldn't believe no one QC'd the vehicle and complained again. Next morning I am called and they said that the Ford dealership had put the intake manifold gasket in wrong and it had been corrected and I could come pick up the truck.
I go pick up the truck and note that not only is the idle still not right, but now the truck is making a hissing/squealing noise when the truck hits 1800/1900 RPM's. Its strange because its not really RPM specific as it is specific to the pedal position. Accelerating or decelerating causes it to go away but its there nonetheless. Whats worse is that in highway driving at 65 MPH, the pedal is in just the wrong position and it hisses constantly. This sound never goes away...and once its been heard its impossible to unhear.
I complain again and they send the truck back to the Ford dealership. At this point I'm dealing directly with the Director of Service because mine has become a high priority case. The Service Director drives with me, confirms my problem and takes the truck himself to Ford. He drives with their shop foreman and they too confirm the problem.
A week goes by and Ford tells him its wind noise. This is complete bullarky because it happens whether I'm going 20 or 65. He calls them on it and they keep the truck another couple days. They call back and say the truck has nothing mechanically wrong with it and that they are done. Service Director goes and picks up the truck and takes it to a second Ford dealership.
Three days go by and they call and claim Eureka! We've found the problem! Clogged catalytic converter causing air flow restrictions. They replace two converters and I go to pick up the truck. It runs like garbage. Further the sound is still there. Call Chevy, leave the truck and take their loaner back home. Next morning Ford's Foreman calls and basically tells me that there's nothing else wrong with my truck and that he even reprogrammed the PCM (which is why it runs to bad all the time now I guess) to get rid of the idle problems.
Long story short here's everything thats been done:
- Cleaned a clogged fuel filter
- Replaced fouled plugs
- Replaced the intake manifold and gaskets
- Replaced the fan belt
- Replaced the fan clutch
- Replaced the water pump
- Replaced two catalytic converters
- Cleaned the throttle body
- Bled the PS system
- Reprogrammed the PCM and transmission control module
After all of this I still have a hissing sound when I accelerate (video 1:
It seems the truck runs worse once its warmed up and even worse once the AC is turned on. I'm sure he programmed the PCM wrong and thats what is causing the truck to run rough.

My 2005 F150 makes a diesel sound when I accelerate. It only does it between 1600 to 1800 RPM and stops. It only does it in overdrive. Its a 5.4 liter with about 95000 miles on it. What this could be? I cant tell if the noise is coming from the tranny or engine.

Why my cig lighter and cell phone charger stopped working. I changed the fuse but it did not solve the problem. I don't smoke but I love to charge my cell phone when I go hunting overnight.

I have a 2004 Phaeton V8 whose engine makes a noise which just shouldn't be there. I occurs if you accelerate the engine (also when the car is not moving) at about 1500 rpm. VW dealer says its okay.

My 3.0 TDI has developed an oil seepage between the air intake damper and the turbo air intake. The oil comes from the blow-by gases hose that connects the cyclonic oil separator to the air intake damper. There is a "hat" type gasket that slides into the air intake damper, prior to fitting it to the turbo air intake, so I bought an OEM replacement gasket and fitted it last weekend. I have just checked it and there is still oil seeping from the very same location. Now I wonder if there might be an issue with the cyclonic oil separator itself...

I have a 2008 VW GTI which I love and have maintained pretty well. I unexpectedly got a job far away from home and couldn't move for two years (!) so right now it has about 70,000 miles on it (poor thing.) Luckily I now live about 5 miles away from work and it's finally getting a rest.
Long story short is that the oil was overfilled during a routine oil change. Foolish me didn't check the oil before driving away (i didn't do the change!) I got about a mile or two before the oil pressure light and beep told me to shut off the car, which I did immediately, and pulled into a shop literally a block away. They bled out some oil and checked a few things out and everything looked fine. But as soon as I left, and to this day (about a month later) I get a strange whistling noise when the car is cold and at low RPM. It's a constant noise and the pitch changes with the RPM (higher RPM, higher pitch) after warming up for a minute it goes away and doesn't come back until the next time I start the car.
My guess is that oil got somewhere it shouldn't have, like the turbo? And now something is leaking, like air? The car drives fine, no stutters or significant loss of power. Is there a way I can diagnose the issue myself before taking it in? Or should I leave it be and let the professionals take a look?

Yup, my truck randomly whistles while driving in cold temperatures. Its not life threatening or damaging to the truck, its been doing it for a few months not that its been getting below freezing. Its just REALLY annoying. I can even hear it over my radio at times, so its pretty dang loud outside of the truck. The noise originates from somewhere under the hood in the engine compartment.
Won't do it at lower speeds, usually on the freeway. Motors at about 2k rpm and im going roughly 65-70. Change the rpm when it whistles and it goes away. happens randomly from 50mph to 70mph engine speed from 1.8k to 2.5k rpm. I've tried to find it but can't find a darn thing since it won't make the noise while sitting in my driveway. What it might be?

Whistle thru intake. I have a f150 2005 with a 5.4 and it likes to whistle when cold weather when I press the gas it goes away until it idles down?

My truck started making this whistling sound a few thousand miles ago. Its a high pitched squeal coming from somewhere under the hood. There doesn't seem to be any pattern or certain time when it does it. Ive read on here about an alternator problem on these trucks. Or could it be my S&B intake?

I have noticed a moderate engine vibration at 1500 rpm on my R32 2008, but if you go to higher or lower rpm you cannot feel it anymore. I thought it could be a missfire, so I checked all ignition coils and changed the spark plugs but without improvement. Could it be the engine belt pulley?

This truck is from Canada. I need to convert speedometer cluster from kilometers per hour to miles per hour. The kilometers are on top and miles per hour under them. Want to convert. I have viewed kits to change the face. They have the miles per hour on top.
BUT! Does the tranny need to be re calibrated?

I have a 2008 Chevy Express Explorer conversion van with a high top. We purchased the van used in great condition in 2011. The sunroof leaks. It always has. I first called the Explorer company to ask what we could do. They said we needed to replace the seal. We ordered one from them and had it replaced. I was desperate to have it stop leaking that I had my husband put clear caulk to try and seal it up.
I am at the point of putting a tarp inside to keep my kids (4) car seats dry. The water has already damaged so much. Even the wood colored plastic now has a white haze (would like to know how to fix that if possible). Most of the water soaks in the ceiling around the sunroof and spreads out and down to the windows and in the upper cabinets. Is there anyway to fix this without having to spend more than we owe on it.
