Golf IV / Jetta IV :: 2005 - Weird Sound When Starts Kicking Into Boost?
I'm the proud owner of a 2005 MK4 1.8t gti, and recently it started making a weird sound when it starts kicking in to boost, where it would normally make a whistle sound while the turbo spools up it now makes a sound that reminds me of a supercharged car, it feels like it could be a leak but I don't have an ecl popping up, it does kind of platoes in the powerband, I hope I'm making some sense ..
View 24 RepliesGolf IV / Jetta IV :: 2001 - Weird Turbo Spooling Sound By Passenger Side?
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 RepliesGolf IV R32 :: Turbo - Misfire Under Boost / 1k RPM Idle (high)
Car started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
Golf/GTI VI :: Boost Leak Between Exhaust Manifold And Turbo
I have a leak between the turbo and the exhaust manifold. The golden clamp (c-clamp? v-clamp?) broke, and now there is a gap between the two. The dealership doesnt cover it under powertrain warranty (my car has passed regular warranty) but worst of all they do not sell the clamp on its own.
I posted a link to a picture below, it isn't my turbo.

Golf IV / Jetta IV :: Turbo Flutter Over 20 Pounds Of Boost
I have an 03 GTI 1.8t with the stock K03s turbo and i used to boost to 25 pounds. Had to put a new motor in and now i when i boost above 20 pounds i get turbo flutter and loose boost. I can boost anywhere up to 20 pounds and the turbo doesn't flutter at all.
I had a spring on my waste gate which i have taken off and it changed nothing. I tried a different diverter valve and it didn't change anything. I unplugged the MAF to see if the N75 or the there was a boost leak and extra air wasn't being monitored but still changed nothing. It has nothing to do with my RPM range just when i boost over 20 pounds. I am planning on doing a leak down test to make sure there isnt a boost leak....
Golf/GTI VI :: Blown Turbo / Slight Boost Leak
Recenly, i feel like i haven't been hitting boost, so i went to get an oil change last week. I did the oil change, and everything seemed ok, I thought it might have been a slight boost leak. This morning i check my drive way to see a little oil on it. So i check the dip stick and the oil level is already at a minimum. Do you think i have a blown turbo due to the oil drop and lack of boost. It hasn't been a 100 mi since the oil change either.

2012 TDI ... OK so out of nowhere, my car is making loud turbo whoosh noise, while I love the way it sounds, it's not normal or intentional, so I don't like it lol. I have an AWE intake, and a gutted turbo resonance damper. Is been fine and same sound ever since those mods but now out of nowhere it is really loud with the whooshing of the turbo.
Small video of it... [URL] ....
Pictures of turbo area .....
Anything look wrong? I circled that one area but wouldn't know if that's normal or not....
Golf IV / Jetta IV :: New Turbo Installed / Wastegate Opens Early Without Building Much Boost
I recently installed a k04 turbo, when I try and accelerate hard my wastegate just seems to open up very quickly without building much boost. I don't have a boost gauge or anything like that installed. Do I start by adjusting the wastegate actuator, or install MBC. Pretty new to this still.

Golf/GTI VI :: 2010 - Weird Noise Almost Like A Wet Belt Sound
Car- 2010 mk6 gti...
Motor- 2.0T with stock turbo, chip, apr intake and muffler delete...
For the past week when i go into boost I hear a strange sound, almost like a wet belt sound (everyone knows that annoying sound on old ford on a rainy day) Again it only happens when in boost. When the car idles the noise is gone.
Not really sure on where to start with this?
Golf/GTI VI :: Weird Sound Coming From Back Area While Accelerating?
When I accelerate as the car is going to shift, there is a weird noise coming from the back area. It sounds as if it were a bunch of walnut shells being crushed and swished in a coffee can. Is that something that sounds like it could be normal? Today was the first time I drove with the windows down and heard it. I'm wondering if it has always been there... it sounds very loud though. It echos very loudly back into the car from nearby things as I drive by... It sounds to me a lot like when you would take a wind up toy past it's point were you weren't supposed to...

i started hearing this weird creaking noise about a month ago. When it started happening it would only occur at very low speeds and then it would stop, now it happens all the time unless i'm turning. I've heard it could be bushings but I'm not sure. What weirds me out is a lot of the time it'll stop either when I'm turning or if I shift into neutral.

Passat (B5) :: 2002 - Leak In Turbo / Weird Siren Like Noise
Turbo leaking? Is it costly to fix? I have a 2002 Passat, V-4 engine. I just took it in to get my oil changed and the mechanic told me that there's turbo leak. I have also been experiencing a weird siren like noise when I drive and the car feels like it's struggling whenever I go over 40 mph and or driving up a steep hill.
View 8 RepliesGolf IV / Jetta IV :: Knocking Sound From The Turbo?
So, I have a 2005 gti 1.8t, has 110k on it, just did a 3" straight pipe, and while a buddy and I were installing my new pipe, and straight pipe, he said my turbo seals were going bad. I could get the k04 cause it handles better, or get a rebuild kit. Well, today when I give it throttle, it almost makes a knocking sound from the turbo? Not from the front of the car, but at the end of straight pipe, you can hear it in that constant spool. What could this be? Time for the k04. Car has unitronic stage 2, so it gets ran hard sometimes.

It starts and idles fine and drives fine until the turbo spools and gets past atmospheric.. at this point the acceleration gets worse even though you can clearly hear the turbo blowing (gauge well into the yellow).. checked the ground connections on the head and intake, seemed good, replaced tps, replaced knock sensor, replaced hall sensor, tried another ecu, checked cam timing. Had a volvo mechanic friend looking at it prior to my fiddling with it and he seemed to think the ignition timing was retarded too much.. but I've done everything i can think of to tackle that problem.

My passat turbo went out a while back and cant figure out why? The Idle is the same as always was, engine is smooth while driving and changing gears, but the boost is very very low but not completely out. All vaccum lines are connected and cant hear the diaphram releasing like it used to abviously cause there's no pressure.

I got my APR ECU & APR Intake done at the same time about a month ago. After both the upgrades I hear the turbo winding and a slight blow off sound more between shifts. Is this due to intake or ecu tune? My brother drove my car yesterday and asked me however I told him I'm not sure...
