Passat (B5) :: Turbo - Chirping Sound Like Something Is Spooling For About A Minute Or 2
I got a b5 passat and when i start the car and drive it even when its warm if I don't let it sit for a minute or 2 and i just take off it will make chirping sounds like something is spooling but chirping until about a minute or 2 could this be my turbo ?
I feel like the turbo isn't getting enough oil or something into it so its making this kind of sounds until it gets the oil.
Passat (B5) :: Turbo Spooling Wide Open Upon Start
Every time I start my passat after it sits for more than 4 or 5 hours (overnight, workday) it sounds like the turbo is winding up at full rpm for about 10 secs. and then stops. It only happens on cold starts. I've had it in two shops with no luck what so ever.

I just got a 2001 Jetta 1.8t 100k miles, and had some repairs done - timing belt - K03S Turbo - Forge Tip - 2.5 Turboback Exhaust. I bought the car without a working turbo, yesterday I got the car back from the shop and it was a night and day difference..... but to my point, today I had some CEL's pop - Charge Pressure control positive deviation, Pressure drop between turbo and throttle valve, and secondary Air injection system incorrect flow detected. Now I have never owned a turbocharged car before, but when my windows are rolled up and im accelerating, I can hear what I am guessing is the turbo starting to spin over by my passenger side(2k ish rpms+) except it doesn't have clean spin sounds, kinda sounds like bearings are goofed or something. This noise only happens when I am accelerating or cruising? I also have felt really no change is boost or power!!

View 2 RepliesPassat (B6) :: Spooling Slow And Hearing Turbo Whine Slowly Raise In Pitch
My 07' sport has been spooling slowly and I hear the turbo whine slowly raise in pitch. After it gets up to speed the car then gets a surge of power. Previously I could not hear the turbo during the spooling phase and the power would have a light and smooth push like a bed of air under mid-heavy 4th gear acceleration. Seems most obvious around 2.5k rpm from a neutral throttle position. Dealer claims normal function, but it is definitely abnormal. I have also had oil pressure lights which generated no codes and were explained away as the engine being sensitive to the oil Ievel which was slightly high. I thought at first it was the cold weather, but after our 80 degree day yesterday and same results.

Ok so I just replaced the oil cooler, added 2 coolant filters, changed the oil/filter, and both fuel filters, and installed the updated turbo drain tube. I get it all back together, it takes a minute before it will fire but I figured that was normal for not having any oil in the sump under the cooler and changing both fuel filters. Everything seems fine, checking for leaks and I notice that I don't hear the whistle of the turbo so I go look at my edge CT and have zero boost and it stays at zero even if I rev it a bit. Obviously I didn't redline it or run it for very long maybe a total of 10 minutes over several times.
I will note that I did find a plug for the driver side injectors wasn't plugged in the first time I started it, but I shut it down pretty quick and plugged it in. So then after I noticed the turbo not spooling I used the chip to pull the codes and had a whole bunch related to the unplugged harness and one for turbo underboost. Figured it was because the harness was unplugged so I just cleared the codes and tried again, now I'm not getting any codes but I'm also not getting any turbo boost the only code that it is throwing is the P1000 "on-board diagnostic systems readiness test not complete" do I need to go drive it for the learning sequence because I had the batteries disconnected for a couple days?
Ford 6.0L Power Stroke Diesel :: 2005 - Turbo Over Spooling Intermittently?
Having an issue with my 05 f350. Seems when I chomp on the the throttle I get tons of boost 30 lbs plus with no power. Seems most prevalent when starting on a hill , or hard on the throttle off the line . Also getting turbo "bark " when backing off throttle. It's less prevalent when feathering the throttle and usually more noticeable 1/2 throttle or more. I'm thinking could be the Vgt actuator or clogged/ dirty ebp sensor?

When I started the V^ Passat today it made a fluttering/imitation purring kind of sound...not re-assuring at all. What it could indicate? It only lasted a second then fadded out and ran fine.
maybe a belt tensioner or oil pressure regulator or something like that getting up to snuf?
Ford 6.0L Power Stroke Diesel :: 2005 F350 - Turbo Is Spooling Up And Down Constantly
2005 f350 6.0 all stock except egr delete. My turbo is spooling up and down constantly. I can actually watch my VGT duty cycle fluctuate while sitting at an idle too. I've cleared the codes and p0299 always shows up first, but then I'll get p0069 BARO/MAP, and a p0470 exhaust pressure sensor eventually. Sometimes it takes an hour of driving before those show up. I can watch all these values on my torque pro, and nothing seems out of the ordinary other than the turbo opening and closing at will. What can cause this? I hate to just start throwing sensors at it.
View 11 RepliesFord 7.3L Power Stroke (1999-2003) :: Pop When Accelerating With Turbo Spooling Up And Lost Power - Code P0475
As I was getting ready to leave town with the tractor loaded up, I was accelerating with the turbo spooling up when I heard a bit of a pop and lost power (engine still running and all, just very low power like you get when the turbo fails). I wasn't far from the shop so I came back and started getting a lot of white smoke out of the exhaust, it doesn't smell like diesel, probably more like oil. Definitely smoke, not coolant. I pulled it around back and shut it down to go grab AE and scan it and it shows a P0475, starting it back up has light smoke at idle and it idles fine but as soon as you give it any throttle it starts smoking pretty badly.
Researching it looks like the most likely cause for this is the EBPV itself but before tearing it down that far. This is the only code it's showing.
Truck has 272k on it, turbo was rebuilt a couple of years ago but we didn't do anything with the pedestal at that time. I guess in retrospect, I probably should have done the EBPV delete and the resistor fix then but I didn't think about it at the time.
On another note, my AE is not showing any of the system test for some reason, the drop down is blank. I have version 7.0.1, so it's an old version but I'm working on an old truck, so... What that might be? I've got the truck pulled into the shop now to let it cool down. I'll probably let it sit overnight and take the turbo and EBPV out tomorrow unless someone has a better suggestion...

With the windows down today I notice that the turbo spool sounds like a damn laser. Boost leak or bearing. That is the question.

I have a 1999 passat 1.8t with 197k miles. When I drive if you listen really closely the engine makes a pretty cool sound like a turbo winding. It's a really really low whooooooo on the first and second gear. You cant hear it unless you have the windows down and there's like no other cars. Is this normal? My friend said the turbo might be going bad ?
View 5 RepliesLexus GS 2006-11 :: Slight Fluttering Sound When Accelerating On The Freeway
So, lately I've noticed a slight fluttering sound in my '08 GS460 when accelerating on the freeway or up a slight incline. It'll kick in around 2,000-4,000 RPM, and it almost sounds like it's coming from right underneath the center console. I did have an exhaust system installed, then uninstalled, so maybe it's something the shop did, but can't be positive whether or not it was there before (always drive with my music on pretty loud).
View 4 RepliesGolf VI R :: Inconsistent Power - Low Fluttering Sound Under Full Boost
Ok here is my question. I've noticed the power on my car has felt inconsistant for the last little while. I finally got around to logging the car and my boost peaks at mid 20's just over 3000 RPM and then drops fast to between 13-15 psi before I even get to 5000 RPM.
Under full boost I hear a low fluttering sound like the diverter valve opening and closing when this is happening. I also don't get the typical diverter valve sound when shifting when the car is doing this.
I took my diverter valve out and inspected it. I can pushing the piston up very easily with almost no resistance, is that normal? I would think that it should be hard to push the piston up if not wouldn't boost pressure be able to overcome the piston and leak past?
My mods are. HPA tune, HPA catted down pipe, and VWR intake.
Lexus RX 2010-15 :: Fluttering Sound From The Heater Vent On Windy Days
My 2010 450h emits a fluttering sound on windy days. The noise sounds like a hvac flap could be vibrating when the wind hits. The noise is not loud by any means, however can get very annoying hearing it everything the wind gusts hit when you are at a stop. The other afternoon I was doing some basic winter prep under the hood and I could hear it under the hood as well.
I got my 2010 as a Lexus CPO early in 2013 and the noise has been there since day one, it's not something that developed recently. The last time I took it in I got a fail to replicate response from the dealership.
Toyota :: 1993 MR2 Turbo Chugging On Cold Starts
I have a 1993 Toyota MR2 Turbo with about 150,000 miles on it. For the past several years on a cold start (it doesn't seem to matter what the outside temperature is, just that the car has sat for a long time, like overnight), if I try to drive away immediately the car will chug. It almost feels like the car is choking or is not firing. It happens mostly on acceleration above 2500 rpm and in 2nd and 3rd gears, getting worse as you go higher in the gears.
After a few minutes the problem goes away and the car will run fine. Also, if I start the car and let it idle for 5-6 minutes it seems like the car will run fine without the chugging.
