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 RepliesI have a 2012 R with 85,000 miles, APR chip running 93 octane with a HPFP and VWR cold air intake. I was driving my car today (slow driving on highest) and all of a sudden I felt no turbo boost, and heard a weird sound whenever I hit the gas. Car moved but would not get above 3500 rpms and couldn't really get past 60 mph. Again, absolutely no boost (I have a boost gauge as well to verify).
About to drop off the car at a shop but had a couple questions:
1. If the turbo is blown, can I still drive the car to the shop (not too far) without damaging the engine itself?
2. if the turbos needs to be replaced, what are my options besides getting the stock turbo replaced, without getting some crazy setup? This is my daily driver and I don't want to spend money beyond what I need to get it fixed, but it there is a stronger more reliable turbo for about the same as a OEM, I would want to consider... Also price for OEM replacement??
3. Without the mechanic looking at it, I'm just assuming it's the turbo but what else could be the issue? All the lines looks intact and intake is fitted correctly. I did have issues with my cam follower getting damaged at 45,000 miles (there was a hole in it) and I have been replacing it every 20,000 miles since. Didn't have any issues for 40,000 additional miles, but could damage to that cause turbo failure?
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.

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 Repliesi have a 05 GTI 1.8T and recently started overheating while driving. for a few months it would overheat if i idled too long but now after driving for 5 minutes it overheats and also wont build any boost. i could hear a hissing sound after i shut the car and thats coming from the flange where the coolant temp sensor is, but is hissing where is mounts to the engine.
update- i replaced the o-ring on the flange, that got rid of the hissing. the no boost must have been due to the engine overheating, but it is still overheating i guess im gonna check the thermostat next.
update 2 - checked thermostat and it is good so I'm at a loss here.
So I have a 2005 GTI 1.8t and I just recently had a new fuel filter/fuel pump installed.. Now ever morning when I go to start it it starts really hard.. once it's starts it runs fine it just takes me a couple cranks to get it started....
View 6 RepliesThe car is a 2002 VW Jetta, automatic 1.8t GLS. 146k miles on it. Has an external amp/sub wired up by my brother who is an MECP certified tech and has been doing car audio and overall Audi/VW for years.
I was driving, nothing out of the usual, this car is my daily. Stopped because of traffic and my car died in the middle of traffic, the gauges (tach, speedo, gas, etc) spiked immediately, which I assumed meant loss of electricity, but my radio, headlights and everything else stayed on. The oil and Battery lights came on as well. Tried to start it, it was trying to start, and was cranking quickly, but wouldn't turn over. I got it out of traffic. I pulled my amp power and the car turned over and started driving like normal, so i figured there had been a short in the wire and that was what caused my issue. Drove about a half mile down the road, car shut off again, car said it needed oil this time. checked the oil, there was plenty, but i put more in to be safe, and it turned right over and i managed to drive it about 30 minutes and got it back to my house.
So, my brother and i look the car over, couldn't find anything really wrong with it, so we took it out for a drive, no problem at all for the first few minutes of driving. Car shuts off again, doing the same thing, but just the battery light came on. My brother jumped my car, it turned over, but as i started to drive it, it was a lot more rough with shifting (possibly tied to electrical problems because i know there is a solenoid cluster for automatic transmissions), i mean you could actually hear the gears shifting and the car was kicking through each gear, as well as my driver side headlight not turning on (just installed brand new xantec 6k 55w HIDs, but i dont think those are the problem because the problem started before i installed the HIDs) and died 3 more times before i got it home, having to jump the car every single time with symptoms the same as the first time it died without the oil light. Another thing i noticed is that the car seemed to only die when i hit the brakes and the car went to low RPMs, which lead me to believe a major vacuum leak. At idle the car also seemed like it was misfiring even though the CEL was not flashing, it just had the jerking feeling and sound of misfiring.
My brother and i take a better look into the bay area, and noticed that the top of my engine was covered in oil, from the intake manifold back. I know my car has been leaking oil, but not spraying it. We pulled everything apart, totally cleaned the engine bay area out including MAF, spark plugs, coil packs etc. The engine bay area looked practically brand new. Now i do know that my car has had a vacuum leak (no boost gauge to tell how bad, but the brakes were a little bit less responsive and the car was acting as though it was misfiring despite the fact that the coil packs and spark plugs are brand new) and we couldn't find where it was, and we thought that maybe that was the problem. A lot of the vacuum line was dry rotted and falling apart and some parts weren't even connected anymore from that, which we replaced all of the line we could find to eliminate the idea of a vacuum leak causing the car to die when i hit the brakes. We also tested the battery with a multi-meter which read variably between 13.8-14 V, which if i understand correctly is within normal range, but oddly enough we put the battery through a stress test including turning on defrosted, turning sound system back on, headlights on etc, and the voltage didn't read much different, still bouncing between 13.8-14.
When tearing things apart, we also found that the starter solenoid was unbelievably loose due to a bad transmission mount, and one bolt was missing, so we were thinking that could be arcing causing the problems, but when the solenoid was tightened down, the problems still persisted.
Started the car, let it warm up, and it seemed perfectly fine. I drove it into town without problems, but forgot my wallet at home, so i had to turn around and go back. Almost made it home, the car died while stopping at a stop sign. Tried turning it back over, nothing the first 3 times, let it sit for about 5 minutes and the car turned right over as if nothing was wrong. Died again when i made it into my driveway about 0.5 miles away and the symptoms repeated until the car finally just turns on like normal now, but the idle is at 1100 RPMS (not sure if related or not) even though the car is at the optimal temperature. I tried driving it again after the car starts normally like it does now, but it just repeats the symptoms that it has been, cutting off but leaving the stereo, headlights etc on. I managed to get it back in my driveway.
So I have a 05 mk4 golf 2.0 automatic. Ive noticed that when i take it from park to drive the car shakes and makes a huge clunk sound like I just got hit by something. Turns out it was a motor mount, I think they call it the dog bone cause its attached to the body & engine of the car. So it was replaced but the car still does it. But not as hard & not as much. Before when I revved the car it would kind of shake and dance. Since the replacement it parks still when I rev it. But that noise is still there. Someone told me it could be another mount or the torque converter.
View 2 RepliesWhen I turn off my 2010 Golf TDI it sounds like a jet shutting off. I've had the car for over a year and it just started doing this. Is this just a noisy fan winding down?
View 12 RepliesSo my jetta is 2001 i believe and idleing like its got major breathing problems, it goes from 700rpms to 1500 in cycles and sometimes dies out all together. I thought it was some kind of vaccum leak and had a few pipes in the engine bay replaced but it didnt fix it. Its also missing a muffler so its really load and annoying, especially when im at inn n out in the drive through lol. Other than that, the car doesn't seem to be running that bad but the check engine light is on as well as the traction light comes on sometimes for no reason.
View 1 RepliesI have a 2005 jetta 2.0l sedan manual transmission. I recently replaced the front shocks/struts and coil springs. I so replaced the passenger side tie rod end and the passenger side drive shaft or cv axle (not sure what its called). Everything went fine or so I thought. There is a metallic whirring sound coming from the front end and idk how to fix it. I don't even know whats wrong. I went over everything multiple times visually and could find nothing wrong. I tried three different cv axles thinking that was the cause for it and the noise remains. The first two were brand new from autozone and the last one which is still on the car is a good used oem cv axle. I took two videos of the noise....

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?
not sure if this is normal or not. usually ONLY comes when I turn my car on for the first time of the day. (cold start obviously, keep in mind its cold where i live at this time of year), there is a weird whistling like sound. goes away when the rpm gauge hits 10/ after 1 minute of the engine running. at odd times it will come on again after leaving the car off for a few hours, after work for example. I was told it because I'm using the wrong coolant??
View 4 RepliesWhen 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...
View 13 Repliesi have a 03 gti vr6. 24v 6 speed. it started losing coolant the other day. but the thing is the radiator all the hoses and the water pump(s) are all dry. its fine when its cold, holds coolant just fine. but when it warms up its only fine at idle, so im guessing its some sort of pressure related leak. the car goes through half a gallon every mile or so. only the inner fender on the left side is soaked and the suspension components on that side as well.
View 13 RepliesWierd new noise from my brakes - No issue when I press the pedal, and they work just fine. However just as I'm about to come to a complete stop the brakes feel like the ABS starts kicking in. I can make it not stop by lightly pumping the brakes but this can't be right. What it could be. I just had CV boot replace if that could have done something.
View 1 Repliesmy car into VAG COM and since then it hasn't boosted past 4 lbs. it has Revo stg 2, K04, aftermarket side mount, full exhaust and a couple other bolt ons. Before the car was spiking at around 23/24 lbs. after pressure testing the system I found that the turbo inlet pipe was lose, so I tightened it. Still no change. I tried holding the battery terminals together for 10 minutes to reset the ecu and I also tried clearing the codes through a handheld code reader. No codes even come up anyways for this. The car is a 1.8T.
View 4 RepliesI just bought my first 2001 Ford Excursion! It has 170k on it.
Question 1 - When I ease into acceleration, my truck starts kicking/ jerking. But if I step on the gas to punch it, it gets up and goes, no kick. While the kick/ jerking happens, the tack doesn't move and the speedometer don't do anything abnormal! What that might be?
Question 2 - this truck came with a VHS player in it, and it doesn't work. The VCR is turning on, but not the screen. Is there a certain way to turn the screen on?
So my 2001 1.8t Golf is having some issues holding boost. I have a Gonzo stage 2 tune, CTS FMIC, Forge 008 Diverter, Silicone inlet and MagnaFlow Exhaust. I've also done the whole Evap, SAI delete and installed a catch can.
Starting in 2nd or 3rd at WOT the car spikes up to 18psi and then progressively loses boost throughout the rev range. Close to redline the boost drops to 5 psi or so. It seems to be dependent on the revs. In fifth gear the car holds 18 psi much longer as the revs don't increase as fast.
There are no CELs. I've done multiple leak tests starting at the air box and plugging the pcv/catch can system as well as at the compressor side of the turbo. None of the tests revealed a leak anywhere in the intake system. However, when I stuck my ear very close to the valve cover I could hear what sounded like a very small air leak coming from inside the valve cover. I took a look at the wastegate actuator and it seemed fine, no play in the rod, no loose bolts and to move it just requires enough force to compress the spring and it returned to its original position.
My thoughts are that it could be a fueling issue or turbo in the process of dying maybe.
