I have noticed that when I have my ac on, I can hear the turbo spool and release noise (pshh sound) more prominently. I drive a 2011 GTI MT. Car is bone stock.
I was just curious to see if this is normal or indicative of a boost leak? If it was a boost leak, would there be a CEL?
My car is Stage 2+ (mods are in signature). I noticed today a hissing noise coming from the rear of the car when my music was turned off. The sound is very similar to turbo spool but I'm 100% positive it is coming from the rear of the car not the bay. The noise does not show up until I hit 3rd gear and from then up it only makes noise when I'm accelerating. Under any load the noise stays the same. I can accelerate slow or accelerate a little harder and the hissing noise remains constant. The only two things that I can think of are the flapper valve on the SPM exhaust and the rear diff. However, I don't see why the flapper valve on SPM's exhaust would be affected by a certain gear.

The turbo attempts to spool and then gets stuck almost like sputtering and then misfires. "Sputtering" can last anywhere from a second to until you let off the gas. If you slowly climb through the revs it doesn't do it but if you punch it you're guaranteed to get stuck. I don't have a boost gauge to see if it's spiking but I'm running out of money, time, and options. I've had my car at my normal shop and they can't figure it out and the dealer techs are stumped too. Oil was changed last month and I did a seafoam treatment before I changed the oil.
Mods:
- CAI
- Unitronic Stage 2
- 225 TT DV
- Techtonics 2.5" DP with high flow cat followed by 2.5" straight pipe
- ST Coilovers Maxed out
- Corvette Sawblades 17x9.5 square with 38mm and 33mm adapters. Front and rear tires are different tread, and size. Fronts are all season 205/40/17 and rears are a summer 215/45/17

Things that we've tried:
- New MAF
- Flashing back to stock and reinstalling the file as welling as trying lesser flashes (stage 1, 1+)
- New plugs
- New coil packs
- New throttle body
- Boost leak test (no leaks)
- Front o2 sensor
- New crank position sensor
- Throttle body position sensor
- New N75 valve
With the windows down today I notice that the turbo spool sounds like a damn laser. Boost leak or bearing. That is the question.
View 20 RepliesAnybody have any issues with this? I have a week old r-line and had the epc light come on, turbo seems to spool heavily with little throttle input and seems a bit sluggish.
View 6 RepliesIt started after a blue spring upgrade. my turbo would not spool until we revved the engine hard then it kicked in and it's kinda worked since then.. it feels like the truck is struggling on acceleration and the boost builds fast up to 30lbs, the EBP seems to be stuck at 21.48psi until your in 3rd then it jumps and I have power again, also the turbo dumps (farts) if I let off even a little until the EBP jumps then no issues. I replaced the sensor and it's stuck at 21.48 all the time.
Now, I unplug it and it jumps between 26 and 28psi, plug in the old sensor while it's out laying on the motor (not installed) and right back to 21.48. I don't know where to go with this and it's my only truck so I need it running. also it was blowing the intercooler boot off at the turbo during a normal acceleration and the turbo spool has a howl to it when EBP is stuck...
I have a 2011 that does not currently have the complete factory exhaust system on it and no muffler. With the nice weather I have been driving around with the windows down and hear a noise out of the exhaust that sounds like tires spinning on wet pavement when I let off the throttle or at some shifts of the transmission. Boost seems normal, and don't hear any noise while under load. I think it is just the VGT closing and making the noise. With deleted sys heard this noise in exhaust?
View 4 RepliesWhen I release my clutch pedal to accelerate, there's I guess a "warble" noise is the only way i can describe it. its been like this since i got the car a couple months ago. Is this normal?
View 4 RepliesI have a MT '12 Golf 2.5L with around 8k miles. I always park with the transmission in neutral. When I first start it up in the morning, the engine revs high, around 1500RPM, so I can clearly hear the engine inside the car. I start it, it revs up and holds, and when I release the clutch I hear what sounds like a rev, but the tach doesn't move.
I believe the GTI doesn't need the clutch depressed for the entire turn over, but the Golf does, so I have to hold it until the engine is running. It may not be a big deal, but I'm just wondering why releasing the clutch in neutral would make a noise. I don't hear it any other time than at start up.
I noticed that the turbo sounds kind of weird when it first spins up in 2nd and 3rd gear. Kind of a rattly whoosh noise before the normal whistle. Is it normal? I thought it was the "noise maker" thing, but FWIW the 2011's don't have it.
View 4 RepliesMy car is a VW golf GLS 1.8L Turbo 4dr Hatchback with a manual transmission, and has had modifications to the intake as well as the exhaust. Recently the clutch would grind every time I shifted gears and let go of the clutch. When I would let go, there would be a grinding noise that I could feel at my feet, but the car would still go albeit a slower rate. I could eventually reach a higher gear and then drive normally around because the grinding would lessen as I shifted to higher gears. In addition to the grinding, there was a faint smell of burning coming from the front left wheel. I was wondering if this is because I need to replace my clutch?
View 2 RepliesCouple months ago I picked up a 12 GTI. This is my first car with a turbo so I don't know what to expect. I noticed on days that are in the high 70's and 80's when I'm accelerating I can hear what sounds like air from the turbo.
I took it to my dealer they did a full inspect and said nothing is wrong. Noticed a small creaking noise from the radio/dash??
Have had this grinding noise going on with my 2001 gti GLS 1.8t, the cam chain tensioner has been replaced recently. Would really like to get this solved and fixed, car has 81k miles.
Found this video on youtube, same model and exact same noise as mine : [URL] ,,,,
Is it normal to have this rattle noise that is coming from the CAI which i never noticed before? This only happened after installing a turbo back and car runs fine. It just sounded like marble got sucked in the intake or 2 thick plates banging. I am pretty sure its not the heat shield for the filter also because i tried holding that and looked at that part. Went under the car too but i cant pinpoint where its coming from but maybe inside the engine?

I also got a pronounce rattling at 2000 rpm when I let go of the gas that's located maybe at the bottom passenger side. I am thinking fuel lines?
I noticed last night that my cars turbo had a much louder whining noise when I accelerate. There is no blow off, doesn't sound like much air coming in and also there is not very much boost being put out at all. I've come to think that it may be a loose seal or gasket along the way but I'm sure hoping it isn't a pooched turbo... I don't have a boost gauge so checking boost pressure isn't an option right now. Just noticed from putting foot down but no boost.
View 1 Replies2012 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....
when I bought my 2003 gti 1.8t it had a small exhaust leak, I decided to investigate today and found that the downpipe flange and turbo flange was rattling around, there's almost 1/16" of play and it's making a rattling noise. I can't tighten the nuts on the studs any more but that might just be from them being seized in place. I'm getting a new gasket and studs and nuts and hopefully that will fix it?
View 3 RepliesI got my 2011 Tiguan today but the manual is being shipped up so I don't have it yet. I got it home (I love it), and I stopped at my mailbox and engaged the parking brake. I had engaged it before and only had to let up the clutch and it would disengage. This time it stalled. I started it again. Pushed the parking brake button down. It would not release. Pulled it up. It would not release. Simultaneously pulled it up and put my foot on the brake, and it released. I know it's gotta be easier than this, but I don't know the trick yet I guess.
View 11 RepliesThis morning I noticed my Trunk release button by the steering wheel, and the release button on my key fob won't work. Using the key manually does open my trunk though.
I checked, and it is not in the locked valet mode. I do hear a slight "click" when I push either button so it's trying to pop the trunk but no activity.
What this may be? Didn't know if it might be an electrical issue and if there was a fuse to check? Or if maybe it's a mechanical problem and i'll have to get it looked at.
I've recently noticed that my 2013 hyundai sonata would start vibrating/shaking, if I were to release my brakes slowly (It doesn't shake if I release it fast). I was wondering if there are any problems with that?
I do not feel any vibration in the car when I press /slam the brake. The only time I feel the car shaking is when I would slowly release the brake.
When I press trunk release button on dash or the trunk button on key, I hear the mechanism but trunk will not pop open. I press the button and pull up on the trunk, it is still latched. The key will not go all the way in lock on trunk, I assume it is seized.
I have sprayed 3 in1 penetrate in lock mechanism. Key still will not go in far. I cannot get back seat down. I am wondering if something got caught in latch that is restricting movement.
