Passat (B6) :: 2008 - Auto Shifts From Into Or Out Of Park With Loud Bang - Poor Acceleration
Jan 13, 2013
2008 Passat 2.0T auto, started occasionally shifting with a loud bang into and out of park, and from forward into reverse and reverse into forward. No MIL, pending transmission communications error code. Would accelerate very poorly up until about 30mph and then accelerate normally. Shutting the car off and then restarting would usually clear up the symptoms. Started happening about once a week over a 3 week period, and then started happening about about every other day. With it happening more often, had an opportunity to experiment a little, and by shifting into sport mode (which causes the MFD to display the gear that the transmission is in) noticed that the car was not shifting into 1st to 3rd gear, but starting off in 4th. With that and the rough shifts in and out of park, I thought that it was probably transmission related,
With a tranny being $$$$ and the battery being 4 years old, and relatively cheap to replace, I decided to play the long shot and see if a possibly weak battery was causing an electrical problem in the transmission. The battery checked out OK at a couple of places, but decided to give it a shot and replace it anyway.
Installed the new battery (Bosch from Pep Boys $109) and had every warning light on the dash go on with the first restart, along with a return of the harsh shift out of park problem. Shut the car off, turned it back on, drove five miles, all the warning lights went out, and no return of the transmission problem after 5+ months and 10K miles.
Just a heads up - if your battery is 4+ years old, and you are getting any odd problems that could in any way possibly be related to the electrical system - which includes just about every system on our cars - consider going for a new battery. Worked for me.

Truck is 04 supercrew with 5.4 and 140,000 miles. I have the typical shutter when cruising 55 - 60 and just ease on the throttle to pass someone. I chalked that up to the torque converter unlocking, if I punch it instead of easing into it, it will not shutter. As of yesterday, it acts like the converter is going to full lock up almost immediately. It will bang when it shifts and rpm's drop to lock up range. A few times it has killed the engine when I shift into D. No codes at all, I removed the programmer and installed the stock tune, no change, unhooked battery, no change, fluid is good, and twice after leaving stop signs it worked perfect until the next stop. I believe that it is an electrical control problem.

Have an SE DSG w/ PP and 3300 miles.. When under hard acceleration and the traction control light blinks on I sometimes hear a loud BANG from the front - the car pulls great and goes like hell - just wondering is this the VAQ at work - sounds like the car slamming into gear.. Other than that noise the car is a total blast to drive even though it is now too cold to really play with it..

Just a hour ago, driving along about 45, then I hear a loud bang and my truck quits. I get off the road and it won't even turn over. I had a friend tow it back to the barracks and put a socket and breaker bar on the crank and can't move it. All the fluids are fine. Possible seized up? The thing was running great as always then boom. Nothing! It's a 06' F150, 5.4, 97K on it.

2006 ford f150... Mine started out as a misfire problem which I first changed the plugs. I followed the Ford TSB and got all 8 plugs out with no problems. Still misfiring and setting a code for bank 1 catalytic converter inefficiency bank 1. By the way bank 1 is passenger side. After changing bank 2 because the guy at Advance auto said bank 1 was drivers side. Still setting misfire codes and for bank 1 cat. ineff.
So after installing new coil packs and 2 injectors, Still misfiring #3 and #1 and cat. ineff. bank 1. Decided to buy my own code reader, which is a must if you are going to try to work on these new vehicles. Decided to unplug o2 sensor to see where bank 1 really was. Thats when I found out bank 1 was indeed passengers side. Changed o2 sensors. Still misfiring. Decided to buy the true bank 1 cat converter.
Dropped old bank 1 cat and found all of the internal workings all broke up and clogging converter. Truck runs like new. I spent 178.00 for bank 1 converter at pep boys. After spending O approx. 600 in other parts that didnt fix it. I think the spark plugs not being changed until 115000 miles caused the converter to go bad. Buy a code reader and it makes it a whole lot easier to diagnose your problem yourself. and save a whole lot of money throwing new parts at it.

After scouring through hundreds of threads on this forum (which is Awesome, BTW), it seems as if this misfire / rough idle thing is fairly common (which is scary!!). CEL is on steady. Had the codes pulled; P0301, P0302, P0303. At the recommendation of the mechanic, I had the plugs replaced...no improvement. He then replaced the ignition coils...no improvement. Just finished replacing the MAP sensor. This actually had a VERY temporary positive effect. However, after about 5 miles of driving, the misfiring returned. Took the car to the Hyundai dealership, and they acted as if they didn't want to fool with it. They referred me to a couple of local repair shops...????

On my 2.5 SE auto, it feels like the car shifts into neutral at stop lights. Is this the case? If so, is this cause for concern. I know on my old Volvo S60, they removed this feature because it was causing premature wear with all of the extra shifting into and out of neutral.

My GMC Envoy is making a loud reviving sound upon start up and while driving getting louder the faster I go. It also makes this noise while in park. I have Manuel transmission however it almost sounds like the car is in need of shifting to another gear... I'm hoping it's not an expensive problem!! There is no engine light coming on alerting me to a problem. It's a very loud revving almost whining sound.

I have a 2003 GMC Yukon XL 1500 4 WD. Ive been getting a loud bang ( like a hammer strike on the front frame) on occasion only after backing up and it happens after the truck moves forward a bit. You can almost feel the truck loading up and then it gives with a loud hammer like bang. Ive had a tech check the front end and do an alignment. I had thought it might be a brake hanging up.

2005 V8 Phaeton,82,000 miles.
If I ease on the brakes ,no problem but if I hit the pedal there is a loud bang or clunk from underneath,sometimes front and sometimes in the back. It's as if the wheels stopped but the chassis went forward and back slightly. As long as I put the brakes on gradually there is no problem stopping.
When I come off the Interstate and leave the off ramp, the low side of the front end sounds as if there is no shock absorber ,doesn't matter which side is low,they both do it on the low side.
Intermittent problems.
Steering wheel turns and grinding,groaning noises from under the hood, not all the time.
Going over a speed bump in a parking lot causes the same noise I get exiting the Interstate.

My phaeton's gearbox has progressively gotten worse.. When gearing down after accelerating I am regularly getting a very loud and aggressive bang rather than a smooth gear change, I believe the torque converter is on its way out or the transmission fluid is low.
What transmission fluid I should have in the Phaeton is it the 75w90? I want to try and top up the transmission fluid rather than getting the gearbox serviced as the waiting list in Dortsmund is too long and there is nobody nearby that I am aware of.

2001 Ford F-150 Supercrew Lariat 4x4
I was driving last winter when something bad happened. I was on the highway in 4H doing about 45mph (Really bad weather). Suddenly there was a loud bang, like a shotgun going off. The truck continued to run but it sounded like someone was beating my driveshaft with a metal pipe. There is no apparent damage but it grinds and bangs when it drives. The engine runs just fine. I limped it back home with the noises being constant only when its moving.

Ive got a 2013 Accent with 16,000km on it. It has an automatic transmission. The noise is when i pass from R to D, or P to D. It is an intermittent noise, so it does not do it all the time. But when it does, it makes a loud "bang" that can be easily heard and felt in the floor. Ive had it checked by the dealer, but it never does it when its in the shop.
I always let the idle go down before shifting into gear and even if i hold the brake hard to change gears it does it anyway. It doesnt matter if the trans is cold or hot. And no, i never change gears when the car is still rolling, always when i have stopped completely.

I was driving down the highway when I had this loud bang and twang, after inspecting the car I realized it was the left rear seat belt that was broken. The seat belt fails to retract and cannot be pulled. I'm guessing the retractor is the fault.

My 2006 V6 has about 115k miles. I pulled up and parked the other day and with the car still running, heard a loud "bang" under the right passenger side, and then the compressor wouldn't stop, even with the keys out of the ignition...it was still running an hour later when the flatbed took her away to the dealer.
The car was rear-ended 4 years ago and the back hatch/glass, which operates from the air suspension system, hasn't been able to hold itself up in several years. So there probably really is a real problem with the air system.
Here are questions initial questions I have.
1. From what I've read, it is common that a leak elsewhere in the system caused the compressor to eventually fail. The dealer is telling me that the compressor "blew apart inside" and that it needs to be replaced. Is this reasonable given that the compressor was still audibly operating an hour later?
2. The dealer is telling me that they cannot troubleshoot the rest of the air suspension system without me buying the compressor first. Is this a reasonable approach and level of competence? The service went on to say "We don't see many of these." Should I be worry? I am also concerned that I've read stories about dealer service departments who didn't know/didn't offer up that components of the suspension system can be replaced without the whole, very expensive unit.
3. The SUV was in the dealer 3 days prior for a new drive shaft and some electrical repair in the headlight which included the fuses blowing several times. Could there be any connection or does this sound like coincidence? Any thing I should ask them to protect my interests.

I pulled the EX into the driveway today and as soon I put it in park as I was turning it off there was a loud pop / bang noise somewhere in the front. My husband was already taking it to get new tires so I told him about it and he left to go get the new tires. He said he right away noticed it pulling real bad to the right (I did not notice this and I am VERY in tune with my truck). When he got to the tire place they brought out a big bolt they found in one of the front tires. He said it drove fine all the way home after he got the tires put on. I get in it to run an errand after he brings it back and immediately notice it rides lower. We had the exact same tires put on it that we always do. I also notice a rattle noise and feeling under my left foot that is sitting on the floor as I am driving. I wonder if I broke a shock or something but he looked and says he can't see anything broken. I have a 9 hour trip to go on with my children soon so needless to say I am a little concerned.

While driving on a flat road last night my prius felt like it hit something - the car looks fine and no warning lights came. It felt like I hit a massive pothole and then nothing.

Lately almost every morning my brakes have been seized. After releasing the parking brake the car won't budge without a bit of gas and a loud BANG from all four wheels as they become unstuck. And I don't mean a small bang, it sounds like someone whacked the wheel with a sledgehammer. It has been cold, snowy, icy, wet, and very salty here lately, but the car is parked in an underground garage overnight where the temperature is above freezing.
After becoming unstuck the brakes are noisy and very rough. They'll also re-seize at each stoplight, but with just a small bang. This slowly gets better as I use them, until the next time. Is this normal?
I can't imagine it's good for the health of the brakes for this to be happening. I've heard of this happening if a car is left sitting in wet conditions for a couple weeks, but only after 12 hours, and again at each light? I also had the dealer take apart and clean the brakes about 4 months ago.
