Passat (B6) :: Check Engine Light / Rough Idling When Stopped
Jun 24, 2009
Weird problem on my Passat today. First the engine light came on...followed by rough idling. It smooths out when moving, but rough again when stopped. Noticed that turning ON the AC makes it a little smoother...but when you turn off the AC, resumes the rough idle.
Already made an appt with the dealer tomorrow...but wanted to see if this problem is familiar to other owners. Either way, I will update once the dealer finishes diagnosing the problem.
The car has been perfect up to 30k miles...now 2 problems in the last month.

Today I went to the gas station and after I gased up and turned the car on my car started idling rough, almost to the point of cutting out. I started out on the road and my check engine light started blinking. After some time it stopped and just stayed on. The whole front end shakes pretty bad when at idle. The car has trouble accelerating till roughly 35-40 mph then seems to ride ok. I'm not very car knowledgeable, but I do take care of my car. I know I need to replace some of my hoses and spark plugs soon, but am worried that it may be more serious.
What I would like to know is: 1. What could possibly cause these issues and 2.

2001 with the 3.1 6cyl. First thing that started this nightmare is I was noticing a bit of a hiccup after driving for a couple miles. We've only had the car a few months and not sure what maintenance was done so we thought maybe it needed a tune up. Before I got the parts the check engine light came on so I went to parts store to get it read, it was P0302.
Did the wires and plugs and it got worse, the code wasn't p0302 now its just p0300. But after the plugs it also started idling really rough and would be slow to shift. Once it tacked up high and wasn't speeding up. That was only once tho. Also now it has no power its like driving a 2cyl ...
Anyway we decided since the first code said 2 we replaced coil 2, no luck..ok, fuel filter and fuel injector 2, no luck. Also has cleaned various things Im not sure of the technical name for..sensors and air filters and other things.
None of this has worked the car still idles very bad and doesn't have the power it should have. Also cleaned things on fuel rail(?). He is in the process of replacing the crank sensor as someone said if it was all the way bad it would throw a different code but it may just be faulty.

I replaced the heater core in my truck this weekend. The only thing I was worried about was pulling the dash. The truck is a 1998 f150 with the 5.4.. Everything went fairy well and decided to replace the AT Shift cable as well. Got everything put back. Truck runs, no leaks, no antifreeze smell. After running about 20 minutes, it started idling a little rough and my check engine light came on.
The codes are p0136, p0156, p1131, and p1151. I know these are related to the OS sensors. My question is could it be as simple as I miss an electrical connection when putting the dash back in? Was thinking possibly somewhere on the passenger side under the kick plate or possibly something while hooking up the heater hoses? Maybe even a ground that didn't get connected back when putting the das back in?

I have a 09 w/ DSG and 64K miles. Love it. Never had one mechanical problem until Monday. Driving back from SC on I77 N, my check engine light came on and I stopped at an Autozone in Statesville NC to find that a P2015 fault was to blame. Apparently it is:
DTC Description:
P2015 (2968) Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Sporadic
Technical Background:
- Intake manifold tumble flaps sporadically stick.
- Engine performance is not affected.
At any rate, I drove to the bank this afternoon 2 mi +/- and upon parking at the ATM, the idle went way low (under 1000) and then started creeping higher to about 3K. I raced the engine a couple times then it began starting at 1200, going to about 2000 and then back to 1200. Over and over. It's hard for me not to think these two things were related, except the check engine light was off from Tuesday to today. When the idle was roughest today (almost stalling) - the check engine light began to blink. Then it was steady for the 2 mile drive back and under normal driving, I can't tell anything's wrong.

When I turned on my 2005 Passat V6 this morning, it idled very rough and the check engine light came on. Kind of sounded like a misfire. After about a minute or so, the engine ran as it always has....normal. Smooth as ever. Well I had it scanned at AZ and they said it was in fact a misfire from two of the cylinders. So then I called my local VW service department and the guy there gave me a no nonsense over the phone diagnosis, he told me that he owns a V6 Passat and he encountered the same issue on several occasions when the outside temperature drops precipitously over night. He stated that the misfire is due to condensation in the ignition/coil area. He stated that it is in fact a very common problem and that I would be fine and that the light would go away on it's own. The car is running fine. Should I really worry?

I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.

Wifes car began to idle very rough and check engine light began to blink and beep, I took it to the mechanic today and he informed me that my control module was no good and it was a $400 dollar piece. I said go ahead get it done, cuz she needs the car and i couldn't afford to not have it done immediately. Question I have is does this small-ass piece really go for that much on average and what control module is it?

Just noticed the other day the Passat was idling significantly rougher than usual, most of the time it's smooth as butter but not so much lately. It's not rough like a bad misfire, just not very smooth anymore. This could be indicative of the dreaded oil-pump bolt failure rearing it's ugly head (finally)?

I have an 08 Passat 2.0T with 44k on it, just did the 40k service around 42k. This past Friday I filled up from almost completely empty, and later that day and ever since the engine has been idling rough and the CEL came on. Gas cap has been checked already.
Should I wait to go to the Stealership until I've burned this tank of gas out? Is there anything else I can do that you can think of?

I was just at work tonight and went out and started my car for it to warm up (it is -20) and go back inside for about 15 mins, I come out and as I am walking back to my car. I notice tons of exhaust is blowing out from the bank puffing like a steam engine and idling insanely rough with the RPM gauge at about 900 RPM with a EPC code. I immediately shut off the car. Cautiously turn the car back on. Car is idling normally, EPC code is gone, rev it a bit. Everything seems fine.

I recently got an oil change at EZ Lube and since then my engine seems to be running a little harder. You can feel it vibrating more than normal while idling and when stopped at a light when it turns off, it REALY turns off like it's choking out and sort of kicks the whole car a bit when it shuts off.
I just switched the air filter just in case as it seem similar to my old car that would die if the carburetor wasn't bringing in enough air, but I'm not as familiar with fuel injected engines. Could it be the fuel filter or other engine issue?

I am desperately seeking info about my 1998 Honda Civic. My engine keeps quitting on me when I am either stopped at a stop light idling or the rpm's are really low. This seems to happen at random with no warning or check engine light. I keep my tank more than half full with gas so I don't believe this could be it. I have been to my mechanic and they said it could be a multitude of things wrong with it so it doesn't make sense to put money into the car if it won't necessarily fix it. I am desperate to figure something out so it can get fixed because I have to drive to work everyday and I'm sick of feeling anxious while driving all the time!

So, I have a 2011 Hyundai Accent. It drives great. Until recently.
My wife noticed that it was cranking a little longer than usual before starting. Then, one day, I noticed it. So, I stopped the car and restarted it to see if it would happen again, and listen more closely. But, all ti did was crank.
I became upset and went in to do some research and make some phone calls. I came back out and voila, it magically worked fine again. Weird, I thought.
A few days later, no incidents. We go to the grocery store. On our way out, it cranks longer. This time I'm not going to restart it, I think. So, I start driving and everything is great. Except...it suddenly wasn't accelerating. It felt like it was in neutral for like 100 feet or so, then back to normal. We're making plans to take it into the shop at this point.
The next day, we go out to get coffee. Car drives great. On our way out, no problems. We stop at the red light, and it stalls. I have to push it into a parking lot and call the tow. Strangely enough, it starts again ten minutes later, and runs fine.
The stalling and being unable to start for tenish minutes phenomenon has happened three times.
We took it to the shop, it actually did this as I was filling up gas--stalled. I pushed it into a space and waited a few minutes, bam, it started up fine. The mechanic told me that the engine light had been reset. He couldn't figure it out. Said everything looked great.
So, the run down is this:
-My car stalls when idling, but only after it has been driven some, stopped, and restarted without a lot of time passing--like when you're coming home from the store or something, after it sits for 30 or 40 minutes.
-Once stalled, it will not restart again until a few minutes have passed --something like five to ten minutes.
-There is no check engine light. Fluid levels are good. Connections and whatnot, according to the mechanic, looked good.
-When it stalls, all the electronics stay on and work. The oil light and engine light pop up (like this key is in and turned part way), then it all goes away when the car restarts.
-the computer says that it was reset after it does this.

My Avalon has 55,000 miles on it. when it is idling the motor seems to be very noisy. to me this isn't normal my service rep says there should be no problems if there is no check engine light on.
Should not be as noisy with such low mileage. dealers says if there is no problem and that is the way it is they will charge me for the diagnostic fee. seems like it's not right the way it sounds so what is everybody's opinion on this issue. Oil level is up and very good so just wondering if it could be very variable valve timing solenoid making noise.

My 2007 Sante Fe had problem this week. Took 6 attempts to start engine, then ran smoothly the rest of the night. The check engine light came on while trying to start vehicle.
Next day I changed the spark plugs but now find that the vehicle jerks when idling. Runs fine when going but jerks and bucks at stop lights and stop signs. Just added fuel injection cleaner to see if that may support the situation.
Engine light has come back on again since resetting. I have read several suggestions on internet regarding leak in vacuum line, Coil Pack damage due to faulty hose, even faulty 02 sensor.

My car is idling rough and the Service Engine light blinks on/off continuously. I ran the codes and they are P0301, P0401 and P1258. What this could be? I changed the plugs, wires and ignition coils about a year ago. Catalytic converter was replaced around the same time but the O2 sensors hasn't been changed. Could that be the cause?

2000 Ford ZX2 2.0 ....I've got approx. 79,350 miles on this car. I'm the original owner. The "Service Engine Soon" light came on. I took the the car to an Advanced Auto Parts store, they hooked up their handheld computer to the car and told me "it might be an oxygen sensor or poor fuel octane", he suggested adding an octane booster and see if the light stays off. I did that,but two days later it came back on, the idle seems a little ruff when stopped at a light.

So my wife was driving our '10 escape xlt and the engine light came on and it displayed the 'check engine' message on the screen. It has 86500 miles and luckily no problems yet. The only thing that has changed was she accidentally put super premium gas in it the other day. The light came on and after she drove it home (about 10-12 miles) and it sat for a few hours and i drove it about 20 miles it randomly went off while it was idling.
I shut it off and let it sit for 20 minutes and then let it idle for a few and it never came back. It has been running ok. We definitely drive it a lot as she works day shift and i work nights. I'm just trying to make sure there's nothing wrong with it. I got a bulletin a while back about the intake getting moisture in it. I didn't know if maybe this could be the beginning of this or something else. This is a whole new territory for me as i consider my 91 f250 'new'

I am a grad student hoping my car will hang in there till graduation next year. I have about 227,000 miles on my Honda Accord Wagon and recently the odometer stopped working, S light started flashing, and the check engine light came on. This only happens sometimes, and the check engine light does not always come on when the S light flashes and odometer stops working. I've continued driving the car to see what happens and so far, no problems have come up. I have driven another 1000 miles and am hoping I can just ignore the problem and continue driving the vehicle since I am not in a position to fix it or get a new car.
Recently I passed my California emissions test and she seems to be running smooth. Any thoughts or warnings as to why sometimes these signals happen?
I have to drive with GPS on all the time to know my speed, but other than that I feel OK.

2004 Santa Fe 3.5 has started idling rough when in park or when stopped and in drive. When I'm actually driving, it runs smooth and doesn't seem to have any issues or hesitation. I tested my EGR valve with a vacuum pump and it held 7Hg of vacuum and did not leak. I think that indicates it is working still?
I think my issue may be the EGR Solenoid, but I'm not sure how to test it. When I remove the Green hose from the Throttle Body, there is a good vacuum coming from it and my car speeds the idle up and seems to run smoother. I think that means there's some kind of blockage? When I have the Solenoid off, you can blow through it, which I think means it is open.
I think I have to replace the Solenoid, but didn't want to just buy parts.
