Golf IV / Jetta IV :: Rattling Noise - Turbo To Downpipe Flange Loose
Oct 27, 2014
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.

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.

2005 jetta gli 1.8t automatic ( i know flanges are different from automatic to manuel) just recently found the leaking coolant flange. Can I change the flange without having to drain the coolant out of the system. my coolant is new because i recently had the timing belt/water pump etc done so its new coolant and i do not want to flush the system. also will i have to "bleed" the system if i just pull the flange of and replace it if that is possible.

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 have a 99 vw jetta the coolant outlet flange nipple became brittle and broke...its the smaller 1/2 size hose not the two larger ones. Not sure how much coolant actually flows thru there and want to know if i can drive it a couple miles to a shop without it hurting the engine. I believe it's bone dry but don't know and i didnt want to add water since it's 32 degrees COLD. Don't want the water to freeze. The part comes in this weekend ...how far can i drive , with water no coolant....(vw coolant is expensive).

I have a problem with my 2005 gti 1.8t , I had a issue with my cooling flange leaking, I changed it yesterday refiled it with g12 and distilled water took the car for a test drive about 20 min in see the temperature go up, no steam or water leaking any where, turn on the heat notice no hot air from the vents,turn on the ac no cold air, and the fans are not turning on. Everything worked the day before I did the coolant flange, am thinking is this possible because the coolant temperature sensor broke? fans will not turn on at all even if it overheating. If I leave the radiator cap off the coolant is spiting out of the overflow expansion tank don't know where to start looking for some pointers. Would bad thermostat cause the fans not to turn on?I think is impossible that the fans and the thermostat broke at the same time with the fact that everything worked the day before..

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?

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] ,,,,

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.

Bought a used 2000 Jetta, 2.0L AEG engine by the looks of it, 188k miles. Previous owner told me he did a bit of work on it, and acknowledged the coolant leak - have to fill the overflow ball about once a week. He said he recently replaced the timing belt, water pump, and tensioner pulley. Not sure if that has anything to do with it.
From what I can see it seems to be leaking at the outlet flange (see pics of rust).
Would any of this cause the water in the overflow ball to be rusty yellow (see pics)? Should I just go ahead and replace the ball and then the o-ring at the outlet flange?
I'm new to VWs, but am up for a bit of work to make sure it gets to 200k miles (bought the Bentley manual).

So I drove my car (2000 vw golf tdi auto) to work fine. When I started it to drive home, it squealed and then all of a sudden stopped squealing so I popped my hood and looked and the belt can fit 2 fingers under it. Is there anything I can check diagnose this? I hear it could b a tensioner pulley.

Heading back up to get the last load of antique tractors from the show and something seemed funny. 2 miles later turn into a side Road less power. Pull over. Oil everywhere. Shut it down. Nut completely unthreaded.
Get it on and tighten as best I could with a pair of channel locks one size too small. Dump in a gallon of oil. Now it is just on the stick. Start it and sounds good. Still leaking.
Called a buddy to see if he can get me. Yep sure but his wife is not happy. Something about him going to Texas at 7 am for work for a week..... Give him directions hoping he makes it since he has no sense of direction.
Obs 7.3 stops. Talk to him. He doesn't have anything better for tools on him but lives a mile down the road. Drop the trailer on the side of the road. Drive to his farm and got some better fitting pliers. Either I got too heavy handed or I cross threaded it. Stripped the nut. The flange threads look good.
Drive back to the trailer and sit intersection so my buddy doesn't miss it. Hook my trailer to his truck and get mine loaded. In the end it turned out as best as it probably could have. Pictures to follow when the sun comes up. Time to read up on the dipstick flange. Hoping a new nut and o-rings will fix it.

I was driving home and suddenly the underside of my car *popped* and it sounded like my muffler came loose. Very loud exhaust/turbo whistle.
Luckily I was very close to home and was able to pull in when it completely fell off and started dragging on the street. What part of my exhaust is this and what should I do to repair it?
I just finished fixing a ton of stuff on her and now she does this ?

I own a MK4 Golf GTI which has recently started making a rattling noise when I first start the car (Perhaps cold weather?). It will continue for roughly a minute despite load (A/C, acceleration) before It stops and It won't happen again until the car has cooled down hours later. It's quite an unsettling noise and I would like to be set in the right direction.
After a couple hours online I'm leaning towards perhaps the belt tensioner being to blame? I haven't delved too deep into the noise but do believe it is from the left side of the motor. Can likely clarify on the weekend.
Is there anything to worry about? If so, where do I start? I myself was trying to fiddle around and see if the noise would happen at higher revs, which it seems to. [URL] .....

I would really want to know what is causing this sound as it has become louder.
The noise can be heard in this short video: [URL] .....
The noise is coming from the area of the pulleys, and can be perfectly heard behind the passenger side front wheel.
The car is an AWD 1.8T Golf 2002 model.

I have a 2003 1.8t jetta. I got it in the fall and never really needed to turn on my AC until this week. It works, fans work at all speeds, blows ice cold air.
But i noticed today that my fans can be on and nothing. But when I hit the AC button there's a loud rattling sound. Everything works. It's just making noise when the AC is on. Whenever I turn it off the noise goes away.
I tried looking it up and couldn't find anything.

I'm new to the VW family as a couple weeks ago I purchased a 2003 VR6 Jetta. So far I LOVE it and it's been by far my favorite car I've driven. About a week ago, I was visiting my parents back home (I'm a college student) and when I went to turn on my car to go back to school I received the alternator workshop message. I didn't want to take the risk so I took my sister's car back to school and my dad took my car into a local mechanic during the week.
Unfortunately, the mechanic we took the car too does not specialize in European cars (They're just a general mechanic/Ford dealership), but we didn't want to take the risk of driving a car with a potentially failing alternator to the closest VW mechanic (About 40 minutes away). The car was repaired and a new alternator added. All was going well, but I began to notice a slight "clunking" noise when first accelerating/lifting my foot off the brakes. I didn't think too much of it and it wasn't very loud nor severe. To me, it sounded like the interior plastic shifting when I moved.
Anyway, here I am a week later and I'm noticing a lot of noises that didn't exist before, including the clunk I just mentioned. I took a few audio recordings. (For the record, there is NO CEL or any dash lights currently on, thus why I'm not as concerned).
The first audio: [URL] ....
In this link, I'm driving the car around the parking lot in which I park my car here at school. It's mostly bumping gravel, but at the time of the recording I was driving very slow. You can hear a squeaking noise.
The second audio: [URL] ....
In this link, I'm revving the car while parked. Something I've noticed that it didn't used to do is rattle while idling ever so slightly (It's not audible in the recording), but in the recording you are able to hear a slight clunking noise.

I did my pads and rotors this weekend. On the fronts I had some difficulty with the passengers side retaining clip. It was stuck in on the bottom. I wound up bending it out of place trying to get it off, and eventually just removed the caliper without it.
I took it out for it's first regular drive today and there is a rattling noise when the passenger's side goes over bumps (could be front or back, hard to say). I have theorized that the clip is deformed enough that when it gets jostled, it bumps out onto the rim which makes it go twang (which would be consistent, it's a relatively high pitched rattle. I'm going to look at it tomorrow, but I'm not sure what I should actually do. Can I just clip it off? What purpose does it serve? I might be able to get it out with WD40 and bend it in to shape.

Mk4 12v vr6 afp. 170k ish. No real mods except a cleaned up bay. Was death knocking LONG before I started the bay. Probably 6k miles. My car knocks/rattles bad in low rpm but promptly stops all noise at 4k and up. Makes the noise in any gear but only when throttle is applied. Even does it when revved up in neutral. No CEL other than one explained later.
Suspecting wrist pins as con rod bearings are brand new (replaced for no reason they were fine) and i removed head and no problems were found. Lifters tick a bit but that's all. Cleaned and put back with new headgasket. Shined up the pistons of course. Timing chains also done. <10k miles on oil pump. I even tried taking the shifter rod completely out and driving to verify if that was the rattle and no change. What could be left mechanically?
I was afraid the noise was preignition because I was getting codes for knock sensor out of range, so I replaced the knock sensors multiple times each, coil pack, wires, new ngk bkr5e plugs gapped correctly, fuel filter and pump. Have ran multiple tanks of premium 94 from different stations as well.
The ecu pulls timing back to 0 btdc and it is still knocking so I just decided that the knock sensors are picking up a mechanical knock rather than pinging. Only thing left is wrist pins or piston slap. Maybe injectors causing a lean condition?
Here's a pic of my car for attention ....

My 99 Jetta is rattling. The noise comes from the front center of the underside of the car. It started out only when I was accelerating and would disappear when in neutral or after reaching 40mph. Now its when its idling and driving at any speeds under 40mph (I think it just gets drowned out above that speed). I looked under the car and saw that there might be a piece causing the noise but I can't figure out what it is. It seems to be in-line with the exhaust system and its a metal, cylinder looking piece that has uniform holes in it. I'm just trying to figure out what is causing the noise, if I can fix it easily or if this is going to be a pretty expensive fix. (It has 165k miles on it, is a 2.1 gas engine with the new body type).
