Golf IV / Jetta IV :: 2004 - Turbo Is Leaking Oil
Dec 27, 2014
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.

I am looking at a 05 GLI 5 speed with 133k miles. I drove it yesterday and it runs fine, but I smelled coolant after I turned it off. I was told by the dealer that the turbo is leaking some, it was spooling while driving and didn't seem to do anything funny. The check engine light came on and said coolant was low when we got back, when I cranked it back up the light was out. Just not sure about it.

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.

2004 Jetta 2.0, just purchased the car and my first VW. Filled up for the first time last week after purchasing and when it was full (gas pumped kicked off) a small amount of gas spilled out from under the car. Best I can tell from above the passenger rear wheel area. Under a gallon but just enough to make a small puddle. Nothing came out of fill cap or near the nozzle. 2nd fill up tonight and it did it again. I was careful to fill it slowly and went to a different gas station.

Dropped her off at the dealer for the 30k service and minor oil leak near the turbo.
-Water pump replaced (never did whine nor did I notice it leaking)
-Valve cover gasket replaced
-Oil inlet line on turbo leaking
-Wastegate clamp
-Driver side window regulator
Already had my intake mani replaced around 25k miles. Hopefully this will cover all the known/dreaded Mk6 issues. My 1.8T was bulletproof.

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?

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.

I 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] .....

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.

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?

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....

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] ,,,,

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.

I bought a 2002 gti mk4 with about 127000 miles on it .I did not know the turbo fans were blown out , they were sitting in my down pipe next to my catalytic converter . So I replaced the turbo myself , and 2 hours later the fans fell out of the new turbo , what might be the problem ? why it keeps blowing.

My turbo started to have oil on the top of it. I don't know where it's coming from at all, it started to blow blue smoke but not all the time. You can also smell the oil burning off.. someone said maybe the pcv system but not sure. Still new to the vw world only owned the car for about 4 months. Trying to add pics but it's not working.. Will keep trying

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

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.

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?

2003 Golf GTI Turbo... New to VW, I'm a jeep guy and bought a GTI for my wife to try rally cross in. It had some problems that I knew about when I bought it, had to replace CV shafts, control arms, fix broken trans mount, etc. I'm on to the last piece of the puzzle now.
The expansion joint on the downpipe from the turbo is basically exploded. Not a big deal, just buy a new downpipe and biky everything together right? Not so much. Bought one the other day, it showed up and has 3 bolts on turbo side, mine has 4.
When I look at the other stock turbo downpipes, it looks like they have 3 bolts as well. What's going on? Did the previous owner put a different turbo on this? I just need the damn downpipe, but can't figure out which one to order.

2003 Jetta 1.8T. My car has an issue when you're driving and want to take off. I try to step on it and the car gets stuck. There isn't a CEL and one doesn't flash while it happens. 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

- Fresh wheel bearings and custom Porsche 930 Chromoly axles
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
