Golf IV / Jetta IV :: 2003 - Expansion Joint On Downpipe From Turbo Exploded
Mar 5, 2016
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.

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?

I recently bought a 2003 VW jetta 1.8T with 150,000 miles on it. After the purchase I got about 20 miles down the road and it overheated. I noticed there was oil in the expansion tank. I replaced the head and head gasket on the vehicle. As i was taking everything off I noticed that there was green coolant in the car. WhenI took the head off the pistons were glazed over and a lot of things were charred.
So I cleaned everything and put the new head and gasket on. After everything i cleaned the expansion tank of the oil and put new coolant in. After I drove it around for a little bit and everything seemed fine and there was no oil mixing with coolant. So I left got another 20 miles down the road and it started steaming and the overheated light came on. I checked the engine and there was no oil in the expansion take but the coolant was just pulsing it wasn't a constant flow.

So I recently bought a GTI and started to fix a couple things. It has a P0420 code so I bought a new downpipe to install. Noticed the stock one was missing 1 of the nuts and the stud had broken off. How get this out? Do I need to remove the turbo? Looks like I do need to remove the turbo to use an extractor set.

i just installed my downpipe and i took it around the block and i opened the hood and there was smoke coming from the turbo could it be b.c i didnt put the washers witht he bolts to connect the dp but i put them on really tight or could it be the wd40 i sprayed on to loosen the bolts?

I just had a new downpipe installed and now I am getting a horrible scrapping noise when coming off a dead stop. I got under the car and looks like the downpipe is touching subframe heat shield. My question is should i take it back and have them make some clearance or is there a quicker solution. New downpipe and subframe heat shield.

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

I keep throwing a P0411 - Secondary Air Injection System error. My previous pump was seized so I replaced it, and broke a few of the chintzy air hoses in the process. Now, with new pump installed and new air hoses connected, I can go about 5 days before the code comes back on.
So to recap, I have:
Replaced the air pump
Verified the new air pump functions, yepReplaced the air hoses
Verified connection of air hoses at all junctions
Checked the Secondary Air Relay for function
I have not yet checked the solenoid - unsure how to do so.

Had to get a state inspection this month, and originally failed due to front right outer tie rod and both control arm bushings -- i bit the bullet and had the shop do this work for me, since I am going on vacation this week and i plan on using my car.
Anyhow, got the car back, and now i can hear a light clicking or tapping noise, but i can only really hear it when i put the window down, or if im driving by one of those concrete median dividers. Its as if someone is taking the metal tip of a screwdriver amd tapping it against a hollow metal bowl -- it makes a clicking noise, not a clunking or whirring noise...
I can only hear it when i hit 20mph; any less and i cant hear the clicks. At 20mph, its a slow, faint click that seems to be closely related to the wheel spinning. At 40mph, i can hear it is much faster, but just barely louder. I hear it best at abouf 25-30 mph, before road noises begin to over power the clicks.
Turning does not seem to affect the clicking, nor does braking. Its just constant -- if the wheel is spinning over 20mph, its clicking. Whether i coast or accelerate does not matter. I checked for rocks/nails in my treads, and with the exception of quite a few tiny rocks (which i took out), there doesn't seem to be anything remarkable. I checked my CV boots, and i cant find any signs of tearing or leaking grease...
If it is my CV Joint, wouldnt the mechanic that did my inspection, who caught my tie rod and control a bushings, and who did my alignment -- wouldnt he have also noticed something odd about my CV Joint, if something is indeed wrong?

I need to replace a cv joint on my mk4 golf and was wondering if I will need to get a front end wheel alignment done once I have completed the job...

Not sure whats going on here. Could this be normal and I've just never seen it? I dont see oil ANYWHERE else under there. Just in this 1 spot.

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?

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.

I have a 2003 ford explorer and the back hatch window exploded on my son when he closed it. Glass shattered everywhere even on him. I was told there was a recall on this and ford has stated they were replaced but previous owner says they didn't have replaced. How do I know the difference in the recall hinges and new ones? If the hinges were replaced why would the window shatter like this?

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.

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....
