Golf IV / Jetta IV :: Exhaust Keeps Leaking - Fumes Coming Out Of Engine Bay On Cold Starts
Since day one I've had an issue with the exhaust leaking on my car, right at the flex pipe before the cat. I have replaced it at least 5 times in the last year. Every 2 moths or so it tears the flexpipe right in half, like it's literally in 2 pieces when I take it out. So, I thought that maybe the factory dogbone mount was old and weak, causing the engine to move around more, therefore tearing the flexpipe apart, so I got an new dogbone with poly bushings to combat that. It did reduce engine movement, but the exhaust kept breaking at the same spot. Then I thought that the metal was weak from it being welded so many times, so I got a new downpipe with the cat on ebay for like 150 CAN, and put a new gasket on, and now it still leaks...
Only thing though, is that this time on cold starts (as it is winter, so around -25 celcius) its really REALLY loud, like the exhaust sheared off right after the cat. However, after a few hours of driving it seems to get quieter at idle, but if you give it a little gas, it is quite audible. Also I can see exhaust fumes coming out my engine bay on said cold starts, however if I get down to ground level, I can hear it plain as day right where the pinch clamp is that connects to the catback part.
So, my theory is that, cause the bands on the clamp rusted out so my dad just put those u-bolt muffler clamps on there, which I can see an opening in the clamp, even if they're tight, until the exhaust gets hot and expands, kinda making the seal tighter but not air tight like it should. So maybe that clamp isn't doing it's job anymore and I just need a new one. OR it could be that that stupid flex pipe is broken again or that the bolts holding it to the manifold aren't tight, which that can't be cause i got them pretty snug on there. I'll have to take a look underneath again, see If I see any carbon on the exhaust, which would mean a leak, but I checked a few weeks ago and it was shiny metal, no signs of any leaks.
Car is an 04 golf with the 2.0 engine code BEV if that makes any difference. I double checked and NONE of the hangers are broken, and it's held in the right spot as it should, there looks to be no force exerted on the flexpipe at all when installed in the car, so I'm really confused.
Golf IV / Jetta IV :: 2002 - Exhaust Leak Coming From Either Manifold Or Flex Pipe
So I did the seafoam trick and I came to the conculsion that my exhaust leak is coming from either the manifold or the flex pipe. There was no smoke coming from under the car only a mist of smoking coming up from the back of the engine, probably by the manifold or the flex pipe. I do not see any visible cracking per say. I have attached a picture of the end of the flex pipe and it almost looks like someone may have tried to seal it before? I don't know if that is normal or not as seen in the picture.

Golf IV / Jetta IV :: CEL Flashing When Floor 2004 1.8T GLI
For a while i've been dealing with this problem but its low priority because I never floor my car. The car drives perfectly fine even if you hold it 5-10 lbs of boost. When it goes into 18-20lbs it wont hold.
Symptoms : Only when I floor it SOMETIMES the car bogs down and the check engine light flashes for a little and eventually goes away. Now this doesn't always happen. Sometimes I floor it and everything works fine. I don't have vag or a laptop to hook it up and see what code is thrown.
The car is a 2004 1.8t GLI

Returning to the VW fold. Just purchased a 03 Jetta GL (NO SUNROOF) and after the first rain, the passengers floor board is wet. I have searched the forums and have read many threads about the sunroof drain. Where else could this be coming from? I had a BMW that would do this because the vapor barrier in the door came loose. Is this the same situation? I looked at the panel at the bottom of the windshield and it looks tight against the glass and do not see anything stuck in between the panel and the glass.

I left my the car sitting for a week out in heavy rain and came back to find that the driver side floor was soaked. After searching around I seem to have found the entry point. It seems like all of the water is pouring in from my hood release lever area which I find strange. I put a towel down last night during two hours of rain and came back to find the towel almost fully soaked through. I read other threads on this but the results were inconclusive. Could it be the lower or upper windshield seals? Door seals? Another problem I'm having is water leaking from my dome light buttons after a heavy rain. I assume this is a problem with the sunroof seal, but whenever I search around it feels dry?

2003 Jetta, 1.8T, 5spd, stock, 129k miles. I am working on a friends car and his complaint is the clutch pedal occasionally sticks to the floor and during this sequence it is hard to shift gears. I removed knee bolsters to inspect under the dash and found all linkage straight, all plastic parts/springs in place and no fluid leaks, I removed slave cylinder from bell housing and found smooth operation and no leaks. I guess I could replace both but I am wondering if there is a common issue. My searches have found broken plastic parts, bent push rods and leaking cylinders.

View 4 RepliesGolf IV / Jetta IV :: 2003 - Clutch Pedal Went Straight To The Floor With No Resistance?
So last evening, I went to start my car and the clutch pedal went straight to the floor with no resistance. Car started and was extremely hard to get into every gear. Felt like the only thing pushing the clutch pedal back up was the spring underneath the pedal itself. Clutch pedal was 100% just the day before. Got the clutch line bled (vacuum bleeder) and it worked fine again.
Any clue as to what could caused this overnight?
Its a AWP 1.8t jetta with ASR.. I believe I came across something about a revision in the hydraulic line but I'm not sure.
Golf IV / Jetta IV :: 1998 - Clutch Engages Lower To The Floor / Shifter Stuck In Gear
98 Jetta TDI hydraulic system ... We just received this vehicle from my mother in law, who is not driving any more. It's a cream puff--79,000 miles, beautiful condition. Problem is the clutch engages lower and lower to the floor, and eventually the shifter gets stuck in gear. The brake pedal slowly sinks to the floor when at stops on hills. Our mechanic tells us these two are connected because both the clutch and brake run off the same hydraulic system.
1st time he said the fluid was filthy, and he emptied the system and put in clean fluid. Worked for a little while and then we were back where we started. Second time he replaced a couple parts on the clutch, replaced this fluid, and this time it ran like a dream for a little over a month. Then the problem just returned. Again he says the fluid is filthy, and now we are looking at replacing the master cylinder and again changing the fluid. The theory behind why this is happening is that my mother in law let the car sit for half a year before passing it on to us. She didn't do much driving the 6 months before that either. I've done research, and this doesn't appear to be a common problem by any means on these cars.
Golf IV / Jetta IV :: Stalls Out In Stop And Go Traffic / Bang And Clutch Pedal Drops To The Floor
I have a 2005 VW jetta 2.0 engine 5 speed. Just replaced right control arm spark plugs wires and coil pack. I had a misfire only when it rained and it got rid of it! Driving home in stop and go traffic and My car stalls out a hear a bang and my clutch pedal drops to the floor. I had noticed some fluid loss but nothing was low I checked everything before I left work. I finally get it towed but I can not shift to first I can shift to 2 3 4 5 and reverse. I was in first when it stalled out during stop and go traffic while it was in first gear and i had the clutch pressed in. Everything Ive google says it is more than likely the Slave cylinder that is right below the air box. I found some that said it could be the release bearing in the gearbox for the tranny...

I've got an awd 1.8t and ever since I did my 3" downpipe and cat delete I've had an oil smell both inside my car and from my exhaust. I thought at first maybe it was the valve cover gasket which I did last summer, but it looks to be fine. Also it does smoke out of my exhaust sometimes, but a buddy told me if it was my turbo seals my oil level would reflect the seals being gone, which the oil level hasn't moved. What else could it be? Do I just need to put a cat backin?
