Golf IV / Jetta IV :: Loud Banging Coming From Engine Bay - Blown Headgasket?
Oct 29, 2014
So I was driving home from work in my 2000 Jetta 2.0, which has 115k miles on it. Its a 5 speed and I love the car, even though its kind of a beater. Anyway, coming off the highway and reducing speed, I hear a loud banging coming from the engine bay. It sounds like a car would if a spark plug were blown out of the block.
There is definitely a loss of power and the motor is running rough. The check engine light is flashing at me constantly. I pull off the highway and pop the hood. No fluid loss, no obvious smoke coming from anywhere. I start feeling around the engine bay and I feel high pressure air (exhaust?) being expelled from under the valve cover.
So what could have broken? Cracked head? blown headgasket? some other thing I haven't thought of? Its obvious that exhaust gas is leaking from a cylinder into the valve cover.

I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.

So I replaced my rear coilovers on my gli assuming the driver side was broken because when over bumps it would make a loud banging sound as if it was bottoming out but after replacing them i have the same problem.

1997 Limited SOHC auto.
I just replaced the transmission with a known good one from my XLT but the reverse doesn't work now and there is a loud banging coming from the front when I turn left or right.
It feels like the tyres are slipping on the road, like axle wind up. This happens in auto and 4wd high. What the banging is?

My 1998 Explorer is making a terrible banging noise when driving. It appears to come from the rear. It only occurs when i step on the gas, gives a bang and the car shudders lightly. The bang can be gone for 10 - 30 seconds, and all of a sudden appear again. If I step hard on the gas, it will make a bang! bang! bang! noise.. If let my foot off the gas, it rolls quitely without any noise.
I have greased the slip yoke, inspected the U-joints, checked the rear calipers, opened the rear axle/differential plate - no metal parts or excessive wear were observed.. The transmission runs smoothly, there are no other noises apart from the bang. It is as if someone is hitting the car with a hammer from underneath...

Went out to run some errands this morning, and was alarmed to hear a loud, tinny-sounding banging noise from the rear of the car. It would occur on every bump. little or big; every time I braked; every time I started up from a stop; after each shift to a higher gear; and every time I turned a corner.
I was getting really concerned, as I had never heard a noise quite like this on any car, ever before. When I got home, I pulled the floor jack out of the garage, then went to the trunk to get my torque wrench with the wheel bolt socket on it.
When I opened the trunk, this is what I saw: ...

2004 Jetta 1.8t manual, sport package with about 85,000 miles on it and I've owned it since new.
About a year ago I had a shop replace the strut bearings while it was in for some other things. After I picked it up my alignment was jacked and there was a binding sound coming from the front end. The shop said the sound was just the springs settling in. It did go away after a while. Still don't understand why the alignment was off but I aligned it myself and all was good for a while.
About two weeks ago I myself replaced:
Lower control arms (stock VW) and ball joints (FEQ or Lemforder, not sure which) with R32 rear bushings and poly front (I HATE poly bushings but that's for another time)
Tie rod ends (FEQ)
Front brakes & rotors (stock VW)
I also threw in a oem Audi lower stress brace while I was under there but I don't think that has anything to do with my problem. Then I took it to a shop to have an alignment done on it. Everything is now within spec except that the caster is 6.6 degrees on the left front and 6.2 degrees on the right front. How does this happen?
So now my problem: There is a fairly loud binding sound coming from the front of the car randomly. It sounds like the coil spring is binding but maybe it is something else? it mostly does it when I reverse for a bit and then put it in first and drive forward or forward then reverse so something is shifting front to back. Steering doesn't really seem to have any noticeable effect.

2004 Jetta GLI 2.8 ... Tonight I started getting a coolant leak somewhere on passenger side. There is also a loud noticeable ticking coming from that area but it is NOT the engine. Slow steady tick, just to the left of engine (when looking head on). Car also began to overheat. Coolant reservoir is full, too flow to be honest, but I don't see any leaks from there. No check engine light is on. Car does NOT leak coolant when off. Only when running and putting load on engine. At idle I cannot see any leakage. Thoughts? I'm thinking perhaps water pump? 87k on the car. Original pump from what I can tell. Bought the car a week ago.

I have a 2001 vr6 Jetta automatic transmission. When I shift my car from park into to reverse or drive the whole car jerks as if it's banging into gears. But while driving it drives normal. When I stop and accelerate I feel the same jerking you would say.

2005 Jetta. The car makes a loud deep humming noise once I hit about 75mph, and goes away once I get to about 82 or so. I've taken it out of gear and matched the rpm I get at those speeds, and I don't hear the noise at all. It's only when I'm in gear. What this could be?

I have an 05 jetta 2.0 and I had a loud whine on passenger side of engine. I removed serpentine belt and ran engine briefly and noise was still there. Figured it was water pump or tensioner. and when I was changing timing belt, tension, and water pump I found it was the timing belt itself that was whining. It was OEM original belt with 140,000 miles on it. The belt was in very good shape no tears just used looking. Now engine is very quiet.

I was driving on the freeway(70mph), when a loud pop noise (sound of a blown tire.) Felt like a wheel bearing seized up then felt rough on the road. Got off the freeway and everything looked normal from the outside. No smell/smoke. While driving home on the back roads, i was hearing a rattle from the trunk area.
Lifted the car and noticed a little bit of fluid on the front of the differential. Didn't find any leaks or puddles. Took the fuse out for the haldex, and drove it around, still feels the same but still hear the rattle. Hoping its not the differential but haven't drained any fluid yet.
Ok, well never mind. brake system locked up on me.

2005 jetta. On the highway when I hit about 75mph I hear this loud humming coming from either the engine or the exhaust, I'm not sure. It disappears immediately once I cross about 82mph. What could this be? Why such a specific range?

So I drove my car about a mile to a friend's house and when I went to start it back up 10 minutes later, I got no start and no crank. Just a single loud relay click from the engine compartment. Tow truck tried jumping it and then thwacking the starter solenoid to try and get it going. No dice. Battery seems all good.
Had some interesting things go wrong the day before which may be related to it. First, I was tracking my MPG and fuel trim on a highway trip and the trim and fuel consumption data just stopped coming in. Speedo and RPM data was still coming down the OBDII but I just assumed that my reader took a ****. Later that night I noticed that the lights on my climate control (the manual kind) went out. Tapped on it and it came back on, but only briefly. The bulb looks shot.
No engine strangeness on the drive over or earlier in the day. I drive it most every day. Has 215,000 miles on it.
I'm guessing either a short or bad starter. FWIW, I've also been experiencing the typical starter whine after starting. Was meaning to take it off and grease it. Not sure that has anything to do with it. I also tried rotating the crankshaft to make sure the engine wasn't locked up and it does turn, albeit not incredibly easily. It does have oil on the dipstick.

I'm not sure if this qualifies for a "cold start" but my 1.8T sounds imperfect when I start it for the first time of the day. It'll rev around 1200 RPM, instead of the normal 800RPM idle if I start it after it had recently been turned off for a short period.
It sounds almost like my old car that had an exhaust leak, but not as obnoxious. When it settles back down to 800RPM it really purrs and sounds great. Is this normal?
2003 Wolfsburg Jetta 1.8T, not sure if I wrote that in my profile yet. 41k miles and recently serviced for 40k milage. Has sounded this way before and after the service.

My car has been leaking coolant as soon as you put it in from it looks like the transmission area. Today I filled the car with water and drove it on the interstate to work. The car started getting jerky like it was losing power. So I pulled over and when I did the car shut off. There was excessive smoke under the hood and after removing the oil cap, smoke coming from there also. Tried restarting and it sounds like it just spins. No start. Looked at the timing belt, it's still intact. Put a wrench on the crank pulley and it's turning. What's wrong? Is it a goner?

VW GTI 1.8T 5 speed.
So I've blown the differential on my transmission, it's been blown for a little while. I have basically no transmission fluid at all.
Question: Why is the car still driving normally?
Some time ago I was getting a transmission fluid flush and change, my gear shifter was a bit stiff before the change and after changing the fluid it became smoother.
According to my mechanic that would be the result of changing the fluid.
Question: So then why is my gear shifter completely smooth without any transmission fluid at all and a blown differential?
Question: what will happen if I leave it like this? I'm assuming it will eventually seize up?
