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.
View 12 RepliesGolf/GTI VII :: Compression Surge / Turbo Flutter At Low RPM On High Gears
So I'm wondering in a nutshell; in layman's terms... what is compression surge and turbo flutter if you had to summarize it in a few sentences. I was told that its worse with a tune, but even our stock cars have it? I'm not very tech savvy so on the articles I found and read it's said to be bad and basically happening at low RPM on high gears?

Passat (B6) :: Boost Flutter And Sluggishness
So Im going to post a series of graphs of boost compared to rpms. I also did fueling and wastegate. Im having an issue with alot of boost flutter and sluggishness
Idle lambda is at -1.3
Partial lambda is at 13.5
Graph one showing specified and actual boost compared to rpm
Got rid of the crappy autozone special sunpro boost gauge and installed the newsouth that bill shipped me.
Only getting -10 vac at idle
Spiking and holding around 24-25 psi and then it barely drops at all but it holds at 24psi for a while which is kind of scary....
Golf VI R :: No Turbo Boost - Weird Sound When Hit The Gas
I 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?
Golf 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/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] ....

Anything look wrong? I circled that one area but wouldn't know if that's normal or not....
Golf IV / Jetta IV :: Blow Off Valve Started Making Flutter Noise When Dumping
I recently put a cold air intake on my car and I could hear the dump when I let off of the gas. But I also put in a boost gauge but I think I had a leak in the hose going to the gauge. After I drove it for awhile the blow off valve started making a flutter noise when dumping. I fixed the leak in the hose but the flutter is still there. How do I fix the flutter? A new blow off valve? Mk4 Jetta 1.8.....
View 6 RepliesFord 6.0L Power Stroke Diesel :: 2006 F250 - Turbo Flutter After 50% Or More Acceleration
So I bought my first diesel last night and I'm in LOVE!!! It's an 06 F-250 with 6.0 (obviously). It's bulletproofed, rebuilt FICM, EGR deleted, and 4 inch exhaust IIRC. Previous owner had an issue with the turbo and replaced it. New turbo was DOA so he rebuilt it (sort of) and added a precision turbo (again IIRC) back housing (I think) to it. It has an SCT tuner as well and I have it set on the custom economy tune. Is this normal? Is there something I need to be doing about this?
View 6 RepliesGolf IV / Jetta IV :: Won't Boost Past 4 Lbs?
my 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 RepliesGolf IV / Jetta IV :: Turbo Set Up - Motor Won't Start
Well I have been working on my build for about 2 1/2 years. Built the motor for the turbo set up that I had on the car and a few other goodies.
Now the motor turns over with no issue and I have spark. So I know my problem lies in the fuel delivery. My pump tested fine and I have fuel at the rail. So my next guess is the injectors. After trying to start the car I pulled 2 spark plugs out and they where dry. So this proved to me there's an issue here.
Before I go and rip my manifold off and start pulling injectors is there anything I could check first? I'm thinking from sitting that have gotten dirty and clogged.
Looking for wire diagram for the injectors on the vr6?
Golf IV / Jetta IV :: 2004 - Turbo Is Leaking Oil
I have a GTI with a turbo that leaks oil.I don't exactly know what to do. The guy i bought it from said it had "Bad Seals" I've seen many rebuild kits online for my turbo(KO3) Looking through the kits i really only sea one seal. One single O-ring. So that doesn't seem right but this is my first turboed vehicle so i can honestly say I don't know much. Should I buy the Rebuild kit or should I just buy a new Turbo? Any video to reference too because i don't even know how to remove my turbo.
Also, on a side note. I was being a show off one day and tried speeding off like a dick.I went from first and grinded HARD into second and since then I haven't had first gear. Now i suspect its my synchros. But like i've said before. I don't know much.
Golf 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.

Golf IV / Jetta IV :: Car Loses Boost Throughout The Rev Range
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.
Golf IV / Jetta IV :: Slight Drop In Boost

Golf IV / Jetta IV :: Whistling Noise When Hit Boost
I just recently notice a whistling noise when I hit boost. I'm not sure but it sounds like it is coming from my gauge. I'm not losing boost pressure. I do have a glow shift gauge. The most recent install was the TIP which I clamped on to the turbo but I'm wondering if it isn't on tight enough.
