So I recently got this GTi and I was wondering what steps I should take before putting a bigger turbo on this car and the steps I should take when putting a bigger turbo. What should I do first be for considering a new turbo?
View 1 RepliesHave 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] ,,,,
My stereo fuse had blown off and while trying to find it, i removed all the fuses one by one to see which one was blown. I found the fuse, changed it, stereo was back to life. Only problem is that right before removing the fuses the car was driving normal. After checking the fuses the car seems to take longer to start; starter keeps turning for twice the time it did before. Also it seems as if the turbo is not even there. Btw the car is a golf mk4 tdi 150 bhp 2001 model
View 4 Replies2001 MK4 GTI VR6 put brand new coil pack, wires and plugs in the car because it was misfiring. Was fine for about a week than I got a clogged cat code and could feel the affects. I now have no cat, no resonator, and no muffler. The car is finally driving good and then the check engine light came back. It says only a misfire in Cylinder #3 and when accelerate hard to speed up my check engine light starts to blink until I stop accelerating hard. So my guess is the clogged cat caused that cylinder to misfire but I do not know the actual solution to this. My EVAP hose is semi-pinched and when u squeeze it you can almost kill the engine. The weirdest thing of all is this: driving normal I shift in between 2000 and 3000 RPM and once i get into 4th gear about 2000 RPM......my car starts shaking badly and i feel like my engine is going to fall out. I have searched and the only thing i can think of is a bad injector...
View 3 RepliesI 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 RepliesSo 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?
View 8 RepliesThere 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.

Car is a 02 Tdi Golf 4 Door
I just picked up a 2000 VR6 golf a few weeks ago. been doing lots and lots of reading. It needs a transmission and was wondering what other things should I do why tranny is out of the way. I know some things can either only be done with tranny out or are a hell of a lot easier with it out of way. So what are your recommendations. Looking to pick up a tranny and get this bad boy on the road asap. Car ran great no issues or sounds my buddie just shifted to 3rd on highway and something walked loose in tranny and kaboom she went.
View 5 RepliesI'm getting a remote start system for Christmas and I'm looking at how to do the install myself. I know you need a bypass and an extra programmed key for the system to work. This is my problem, My car only came with one switchblade key so I would have to get one made. Basically if I do an immo defeat on my ecu which is tuned (not sure which company a po did it), will I be able to do the remote start without having to use a bypass and spare. Essentially if I do an immo defeat, in order to start the car they key would not have to be programmed, just laser cut, correct? Is it possible to do an immo defeat with vagcom or do I have to get a tuning company to do it. The car is an 01' gti AWW for reference. I'm planning on going gonzo stage 2+ in the Spring so I'm thinking about just waiting until then and getting the immo defeated with that, if it works with the remote start.
View 3 RepliesWell 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?
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.
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.
View 21 RepliesI have this odd turbo squeal in 1st and 2nd gear WOT at low rpm... turbo is new and was replaced in june of this year... had no issues with it up till probably a few weeks ago when the squealing started... it doesn't happen in any other gear at WOT, just 1st and 2nd... where do I start looking?
Here's a video of the squeal : [URL] .....
1999 Saab 9-3 2.0/turbo, manual, 159K miles. Barely replaced turbo (with new turbo) at 154K miles. Had sluggish power after new turbo installment. I had informed saab mechanic that the car felt sluggish upon receipt, to which he replied I could pay extra for a "performance" tune up. But, now months later the loss of power problem has worsened. Since I paid dearly for a complete new turbo installation I'd expect the same level performance as prior to the old turbo going out.
To be clear: no turbo power upon acceleration, slight whirring noise heard when stepping on gas, turbo pressure gauge stays near end of white zone, barely top of white, but needle doesn't leave white into yellow zone as it's suppose to when full gas is given or when revving up rpms to 4800 while switching gears.... absolutely no power, nothing. I'm relying on down-gearing for some engine power when going uphill - tis' that bad. Also, no black smoke or indicator lights. In researching people mention both vacuum hoses or waste gate come up as possible culprits to turbo-related power loss.
My wife just got his car and she loves it!. its a 1.8t 5 speed. Runs and drives awesome. She had 2 new beetles before this one with the same motor but they both had 2 1/2 exhaust from the turbo back. The jetta will be done soon but it has this slight growl when its idling sometimes. Doesn't seem like its every time or may be it seems more when its warmed up. We had just changed the timing belt and tensioner and water pump but we did it 2 days after we got it so I am not sure if it did it before or not.
Kinda sounds like a bad needle bearing where when you spin it and can feel little bumps in it...don't know if that makes sense or not. You can kind of feel it when your sitting in it but its hard to say because we just got it. I don't remember the beetles doing it though but may be the exhaust kinda made it less noticeable. It did have a code about exhaust something bank 1?? I am thinking the cat might be bad or the o2 sensors. i have more sensors im gonna try but when i do the exhaust I know the light will be on anyway.
While I'm in the engine troubleshooting the AC system, I figured I may as well get into a few other issues I've noticed.
I have a stock 1.8T and my turbo feels like it's surging occasionally. A few months ago my diverter valve started making the "blow off sound" when I shifted (manual transmission).
Is it possible for a faulty diverter valve to dump the boost overboard and cause the turbo, and engine hp, to surge? It almost feels like I let my foot off the gas for a second or two (i.e., engine power is very peaky).
A second thing that comes to mind is a clogged fuel filter. I know VW does not recommend ever changing it so it's never been done. Is this a possibility as well?
Air filter is clean, by the way. There's a K&N washable one in the stock air box and I can see daylight through it so it's not too dirty.
I have a 2000 golf 1.8t 4 door Looking to make my car a little bit louder than the stock system. I am looking at getting a new downpipes from neuspeed. I don't know if I should go ahead to and get a new ecu, I don't have a ton of plans for the car just want to make it a fun daily.
View 4 RepliesI 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....
There's this 1.8t gti I'm buying this week from a family member and we've been trying to solve an issue that we ran into. When accelerating the car there is a hissing noise, safe to say that it is air. Then when accelerating a little harder and you feel the turbo pulling you everything seems fine. But a second or so after , the turbo dies off and so does the hissing noise. Then I can let go of the gas and repeat the process and it happens again.
My issue is that I cant figure it out since I Need to be driving to hear the hissing and the turbo cut off. I looked around the threads but nothing really seems to match my issue. No codes either. On top of that I've never owned a 1.8t and don't know much about its turbo.
