Jetta - Volkswagen :: 2010 - Check Engine Light Came On?
I have a 2010 Jetta with the 2.5L 5-cylinder that recently threw on the check engine light for 2 days, then the light shut off. It began once I started the car on a coldish (~20F) morning after it had been sitting curbside for several days with the passenger side wheels sitting on about 6 inches of snow so the car was listing to the side. The car fired up immediately but ran extremely rough for about 10 seconds (the engine throbbed sharply about 2-3 times per second, which could be felt through the steering wheel & seat, accompanied by a muted clunk) before I turned it off.
During this time the CEL flashed on and off and then stayed on. I popped the hood, peered stupidly at the plastic engine cover, and restarted the car about a minute later and it ran normally, but the CEL stayed on. I drove it for two days (~50 miles) with the CEL on, but on the third day (today) the CEL did not turn on. The car has been running normally for all three days. What might have caused the rough idle/CEL and whether I can pretend it never happened since the car seems to be running normally for the third day in a row and the CEL has turned off on its own?
Jetta - Volkswagen :: Check Engine Light On After Filling Up With Gas
Whenever I fill up my VW bug it has trouble starting .... Starts fine in the morning or if just sitting BUT when I stop and put in new gas it has trouble starting AND then when it does finally start the check engine light comes on and the code says "misfire" which I am sure is a correct code since in fact it has such a hard time starting but why? Why only after filling up with gas ? And what can I do about it ????

I have 2001 Wolfsberg Edition 4D jetta (gas) with 180,000 miles, manual transmission. The engine light has been on for years and years. Usually what I do is take it in for an oil change just before a smog. They re-set the codes. I drive it to my office and back and the light would stay off and I could smog it. Until recently. In April, I took the car in for an oil change. And when I picked it up, it ran terribly. It was lurching like crazy. I had to keep slip the clutch to drive it until it warmed up and the it would mostly start running OK. I took it back to my mechanic and he thought it was a timing belt. I had already changed the timing belt at 119,000 miles.
It seemed odd to me that this procedure needed to be done again after 60,000 miles, but I went ahead and had it done. That did not fix the problem. Then the mechanic replaced the air mass meter. That didn't work. Then he replaced the coils. That didn't work. My mechanic has had the car for a month and can't seem to figure out what to do. He keeps getting different error codes - codes that don't seem to make sense to him. The car needs to a smog (my registration date is June), but he can't smog it because we can't get the check engine light to stay off long enough.
Passat - Volkswagen :: 2001 - Engine Warning Light On / Very Rough Idle
The 2001 Passat 1.8lT has an engine warning light on and feels like it is running on less than all four cylinders.( very rough idle) This is the first time we have seen this particular warning light and the manual suggests that it has a problem with the catalytic convertor.( 170K miles on the car) The car had no symptoms until the light came on today and the car was serviced last week. ( oil change and new tires) It seems that every time I take the car in for service something goes haywire shortly afterward.

My engine is in trouble. A few weeks ago, my check engine light came on. The diagnostics revealed that my Mass Airflow Sensor was done for. I replaced it, and everything was working fine for a week. Then a couple of days ago, my Electronic Power Control (EPC) light came on. The car is really dragging. It have to gun it to make it go above 60 MPH. It's become scary to drive on highways. Are the two issues potentially connected?
View 1 RepliesJetta - Volkswagen :: 2003 - Check Engine Light Has Been Staying On Solid / Code P0674
I have a 2003 VW Jetta TDI and the check engine light has been staying on solid (not flashing) for a couple of months. I took it to my local dealer who tested the computer and said that it was the thermostat and a related sensor. That answer didn't seem to make sense, and unfortunately I didn?t get the code from the dealer at the time. I did though have the code read recently at another shop and it said: "Code P0674 which is #4 glow plug circuit - Q13 - electrical fault sporadic." What this means?

The check engine light came on in my 2000 Jetta and the engine power suddenly decreased noticeably. Got worse quickly and was idling rough, like it was about to stall out (but didn't). Took it to dealership, they said spark plugs were the problem and replaced. All seemed normal driving home, but after 10 minutes, same problem: check engine flashing, weak engine (trouble on hills), and a rough idle.
Two questions: what could it be?
and is it safe to drive back to dealership (~10 miles) or might that cause further damage?
Engines - Lights - Jetta - Volkswagen :: 2003 - Flashing Check Engine Light / Burning Plastic Smell
Last night I was driving in my 2003 jetta on the intersate at 65mph with the cruise control on. As I came into a turn I had to tap the brakes. As soon as I did the check engine light came on. The car was doing fine so I drove home from school. Today I drove the car to work which is a five minute drive, and back with no problem. I later went to grab lunch and bring it home and then I noticed the check engine light started flashing. I then felt the engine start to stutter, as if it was misfiring. We had the windshield defrost when we started to smell a rotten egg smell. Luckily we were pulling into our drive when we smelled the odor. I immediately turned off the car and got out. I couldn't smell the rotten egg smell, but I did smell burning plastic. I didn't see any smoke and could not pinpoint the cause of the smell.
View 4 RepliesTiguan :: Idle A Little Rough - Check Engine Light On
New 2012 Tiguan S with a manual, 800 miles and the check engine light comes. Seems to idle a little rough, at least the idle seems to fluctuate a bit. The real disappointing part is I took it in to the dealer expecting an easy fix within an hour, its now been at the dealer for 2.5 days and they'll have it over the weekend as well. They tried putting several parts in it, still didn't fix it. They called VW who said pull out the new parts, put back the old parts, and apply some software update. Dealer did that, still not fixed.

Filled tank with 8 gallons of 91 octane to top off. One hour later noticed car running rough at idle then check engine light comes on. Could it be the coil pack? Car has been running very well until now, and this Gremlin appears. I don't think it's the gas.

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?
View 4 RepliesAccent MC (2006-11) :: Rough Idle - Check Engine Light Flashes And Then Stays On
I just bought this car from the original owner. She didn't take that great of care of the car. First oil change was done at 8,000 miles for example. Basically if it was broken she would fix it, but didn't do much preventative maintenance.
I just replaced all 4 spark plugs and coils since one was misfiring and didn't want to have to go back in and replace one in another few months. Replaced the AC belt a few days ago since it was cracked and worn. All other belts are fine. I drove the car around for a few hours the next day and it ran great.
Today, the check engine light flashes and then stays on. The car is idling rough at stop lights and acceleration is poor. Previously, the light came on and it was the EVAP system. Not sure which component and I was told it isn't supposed to affect the way the car drives.
Golf IV / Jetta IV :: Overfilling Trans Causing Hard Shifts - Check Engine Light Came On
Will overfilling transmission fluid cause hard shifts? I used ~4.3 quarts to refill. How much should I drain out? My check engine light came on.
Basically, I am having hard shifts from 2-3 and 3-4 in tip mode and auto. more tip mode tho.
-I did a complete solenoid change b/c of cold start problem with n92 solenoid.
Fixed the cold start shifting out of first.
-Did a trans fluid change with Mercon V ATF Fluid works fine.
-Just changed oil on 4th of July last week.
Yesterday my check engine light came on. It's been about 500 miles since the solenoid change/trans fluid change, and 100 miles since the oil change.
Now my Mk4 is having this obnoxious shifting. I am thinking I possibly added too much trans fluid into my system as I do not have the VAGcom tool.
I drained out (bone dry drain till no more dripping from check/drain plug), roughly 4 quarts. I added 4.3 give or take 0.1 quarts back into the car.
Now I'm worried because everywhere I'm reading says anywhere from as little as 2.1 quarts to 3.5 quarts.
Should I drain out 0.5 quarts (because I know theres over 4 in there now) to make it 3.5 quarts?
Or should I just redrain the whole thing and start by measure one quart at a time?
Accent MC (2006-11) :: Rough Idle At Start Up With Flashing Check Engine Light (while Low On Fuel)
I have been experiencing some issues with my '06 rio5 (same engine as your hyundais). this forum is way more active than the kia forums, so figured id give it a shot here.
I am experiencing a rough idle at start up while the car is low on fuel (<1/4 tank). it idles rough for a few seconds, the check engine light flashes a bit, and then it runs fine.
The car is an '06 rio5 with approx 19k miles on it, five speed manual. Also, sometimes after refueling and it will just shut off while waiting at an intersection. Not sure whether these two issues are related, but thought i would mention it just in case they were.
Dodge - Dakota :: Check Engine Light On After Fuel Pump Replaced / Idle Rough

View 10 RepliesFord Ranger / B-Series :: Rough Idle - Check Engine Light Starts Flashing
My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.
Ford F-150 - 1997-2003 :: 2000 V8 Running Rough At Idle And Check Engine Light On
I started out with my 2000 F150 with a 5.4 V8 running rough at idle. It would idle way down slow and then rev up a little over and over. On a couple of occasions it would even die when in drive or reverse. I did finally get a Check Engine light so i put it on my diagnostic program to see what was up. Here is what I got:
P1151 Lack of HO2S21 Indicates Lean
P0171 System Too Lean Bank 1
p0174 System Too Lean Bank 2
After doing some reading up I checked all my vacuum hoses and cleaned my mass air flow sensor. I then got the same codes again after a few minutes of running. So I went to the next thing that was recommended, the upstream bank 2 O2 sensor. After changing it the truck ran fine for a couple of days, no issues. Then all of the sudden it idled a little funny again and I got a Check Engine Light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0300 Random/Multiple Misfire
I reset the light to see if I would get the same again later. Before the light came on again I filled my truck up with gas and it seemed to be running pretty good again. Then a day or so later it set the light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0136 O2 Circuit Malfunction Bank 1 Sensor 2
P0156 O2 Circuit Malfunction Bank 2 Sensor 2
P1131 Lack of Switches HO2S11 Lean
P1151 Lack of Switches HO2S21 Lean
I went ahead and drove for a few days as it had gotten really cold here and I didn't feel like messing around in my shop since it isn't heated. A couple days ago I needed gas so i filled up again. Suddenly the problem was gone again. Truck ran fine idled fine no missing or odd idling at all. That lasted a day or two before it started acting a little weird again. At that point i was down about 1/8 of a tank from full. I have read that there can be issues with the fuel pump.. I am kind of wondering if that may be it now. But I haven't had to deal with this sort of issue before so I am unsure what to check next. The truck always runs fine off idle, it only seems to have the issue when it is idling. I had reset the codes the last time and i have the light on again now. I haven't checked it yet but I am sure it is going be some combination of what i have had in the past.
I have read that the IAC valve can be an issue as well. I had a problem with mine sticking a couple years ago and when it would do it you could just tap it with a wrench and it would idle up. But it never died like it does now and it would also idle a lot slower than it does. Back then I cleaned the valve and had no more issues with it. The truck has always had times when it would act weird at idle usually after slowing down after being at highway speed. The current issue happens at all temps cold or hot.
Golf IV / Jetta IV :: Check Engine Light Blinking And Sputtering On Idle - Misfire?
On my way to work, my check engine light started blinking and car was sputtering (real bad on idle). I ran the code and it came back with misfires codes. I changed the coils/plugs, fuel filter and fuel pump last year. Can the coils be bad already? When I clear the codes the car will run fine for a little while. But after a couple miles CEL will blink and the car will run roughly again.
Car : 2004 Golf 2.0
Codes:
16684: random multiple misfires
16648: fuel injector #2 short to ground
