Golf/GTI VI :: Flutter After Installing New DV
Aug 3, 2014
I installed the pierburg revised DV yesterday because my old DV was shot, squealing and leaking boost. After installing it I noticed that when i'm under around 15 psi and i let it build up that I get this flutter I didnt have before. I assume its the wastegate but I haven't heard it prior to installing the new DV so my fear is that its the valve no circulating and its putting the unused psi back through the turbo (not good).

Going through the drive thru tonight and I heard a weird noise coming from the engine area. Get home and pull into the garage and here a flutter sound when my clutch pedal was pressed down, let go of the pedal no noise. While driving the car around clutch pressure seems fine and no slippage of any kind.

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....

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?

Whenever i start my car and begin to drive, i get a loud flutter/Rattle when i change gear above 2500 rpm. It occurs when i give it about 50% or more throttle. is this normal? or does it have anything to do with cold start? I have a tampa mod resonator on the car.
I have a video to show sort of what it sounds like, but this is with giving it about 30% throttle, not 50%. it gets much louder, and sounds a lot worse when i give it more gas. Listen at 1:07.

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.....

-I currently have a CTS turbo intake, 42DD turboback and installed the Autotech HPFP. After we installed the HPFP and drove around the block I threw a CEL. (not sure the exact code # ) but it was related to the cam shaft.
We were unable to upload the 2+ tune because his computer which has his APR info is under repair. My guess is that I am throwing a CEL because I upgraded the HPFP but do not have a tune for it yet. Who else has installed a HPFP before getting the tune?

So i have been looking to get some new headlights with the projector housing but noticed that most of them have a fog light which my car does not have. I know in order to get them to work properly i would need the euro switch, but would i need to run additional wires through the firewall?

I'm interested in installing a staggered set of wheels on the R. The size I'm looking are 18x8.5 and 18x9.5. My question is what wheel sizes should I run to keep everything within spec of my Haldex unit? Ive read about staggered units having to be within 3 or 4% so nothing breaks down prematurely.

Got my Magnaflow resonator in the mail today. Called up my exhaust shop and they are willing to tackle it but were wondering "where to cut" and "what about the internal baffles". Do you cut and shorten the center of the resonator by 7 inches or do you cut at one of the ends and shorten it from there 7 inches?
The picture I saw on TampaVW's thread shows it having been rewelded from the exit side (IIRC) but what about the internal baffles?

So tonight I got the chance to install my H&R Rear sway bar on my car...let me start off by saying I was lucky enough to have a lift, air tools, all the correct tools, etc...now the frustrating part...i opened the box saw the bar and new bushings, figured this should be 100% straight forward 10 min job... the old bar came out in about 3 minutes...then I got the new bushings on the H&R Bar and went to put the factory brackets on...they wouldn't fit even close. Luckily I had a press so I pressed them on. Once I got the bar in the car I got the two top bolts started and could not for the life of me get the bottom two...its like they were 1/4in to low... Was I missing parts from H&R? also the factory caps/brackets seemed to sit off to the side of the new H&R bushings and there was no way to line them up straight, but I finally got everything on there..

I installed my LEDs put in the fog trigger wire, did the vag com, and on my dash the rear fog icon pops up. BUT no rear fog, I still have a bulb out message as-well. I've triple checked all of my wiring today, and did not see anything wrong. I've tried replacing the bulb.

There is only one DIY i can find that is still alive. I have a megan short shifter. Its already half way in. I just don't have any instructions and i am kind of at a loss as to where i go from here. Does this shifter change the way my reverse gear will be engaged? I mean will i need to pull the trigger up to go in reverse or will i still push down? Does the spring that came with the kit go under the sleeve or above it? Sounds confusing.

Brand new bumper came in without screws and nuts, it's ready for painting but i need the right hardware. (photos are simply for reference)
I want to keep the screws and nuts OEM meaning as close to as exact as possible without home depot or some lame arse hardware store, i'm talking about original VW if possible parts. Or at least the clips if anything at all. VW dealer hasn't supported much either, they just said go to Home Depot and buy some regular screws and u-nuts but I want everything as if it came straight off the dealership. I do not believe that all screws and nuts are created equal and where to get exact right hardware I need.
As far as I know the bottom needs 18 or so 5mm nuts and "u-nuts" that they screw into. And there's also the stock scoop, where to even start with screws on this one.

The strut is lose, I can spin it hardly but I can't get the rotor to go down far enough, already disassembled the control arm but it didn't do much considering I couldn't move it forward or backward so the rotor still sits on a corner or the arm. I did the drivers side already.

Installed a new dampener on the front passenger side. As soon as we lowered it off the jack it was higher. Pulled out of the driveway and lowered a bit, drove around the block settle a little more.
Now, three days later, it is still not level. Do I just need to keep driving it and let it settle? Will it not settle as low as the other because it is brand new and the rest of the kit is a year old? If so is the best thing just to just play with the other three corners till its level?
