Jetta - 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?

I brought my Prius, 128,000 miles, into the dealer with the check engine light on. Runs fine, and checked the gas cap. Toyota dealer said they need to replace 4 fuel injectors, replace oxygen sensor, and clean the throttle body. Check engine light needs to be off so I can pass emission test.
View 8 RepliesCamry :: 2009 - Vibrates When At Idle / How To Clean Throttle Body And IAC Valve
I have a 2009 Camry which has the well known very bad vibration at idle when in drive at a light. My Ultragauge shows the RPM are very low when it vibrates. Sometimes it drops to around 425-450 rpm when at a stop light in drive (automatic car). Then it sometimes moves up to around 625-675 rpm and that is when the vibration completely disappears and it is nice and smooth. This issue is intermittent but happens everyday.
Most people think it is due to a bad engine mount and spend money doing that and get no results.
I have done a lot of research and feel it is due to a dirty throttle body and IAC valve and want to test my theory. I will post results once I do the job. What is the easiest and most thorough way to clean both?
Sonata NF (2006-10) :: Throttle Body Cleaning Due To Rough Idle Occasionally / Code P0106
Trying to clean the throttle body on my 09 sonata 2.4L due to rough idle occasionally (throwing P0106, replaced MAF sensor still same problem), one quick question, is it okay to force the valve open (with connector disconnected of course), and is "re-learning" necessary and what's the proper way to do it?

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 ????
View 6 RepliesJetta - Volkswagen :: 2001 - Check Engine Light Stays On
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 :: 2003 - Check Engine Light Is On / Code Is P0778
We have a 2003 VW Passat 1.8, front wheel drive. The check engine light is on. The code is p0778. When we start the car the gears light display lights up in red for all gears . We put the car in reverse, back out the garage and when we stop, we get a bump. And we shift to drive the car moves slowly with some hesitation.
Sometimes after the car runs for 10 minutes, then turned of for a few second then started up again, the problem goes away. Before this problem started, we would start the car in the mornings, and put in "R" , and only the reverse gear would light up. (which is the way it is suppose to work).

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 RepliesChrysler - Towncountry :: Check Engine Light Comes On / Code P0404 - Clogged EGR Valve
2007 Chrysler Town & Country with 74K. The check engine light comes on and the parts store diagnostic says P0404, a clogged EGR valve. On my model, replacing the EGR valve involves taking out the alternator, which involves removing the passenger wheel. That's beyond my skill set.
So, can I just replace the EGR tube and pour some Sea Foam motor treatment directly into the EGR? Would that hurt anything?
Prius (2004-09) :: Check Engine Light Throwing Code P1121 For Coolant Flow Valve
My check engine light was throwing the code P1121 for the coolant flow valve. Toyota replaced it under a warranty enhancement (I have 134k on it), and since then my mpgs have gone from 46 to 50.
My AC is working much better now, too. My theory is that the valve can be in a semi-failure mode for a long time before throwing a code. Now that My coolant is flowing the way that it should, heat is being dissipated more efficiently.

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 RepliesAccent LC (2000-05) :: Check Engine Light Code P0422 / Slight Valve Cover Gasket Leak
I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.
After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.
Other things which may serve as clues:
Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)
When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.
Car has 107K manual shift.

I repaired engine as follows new head & bolts head gasket timing belt water pump coolant flange on drivers side new fuel rail and injectors car also has new coil pack, new VW plug wires and 1 week ago new iridium plugs my brother didn?t want car, so i bought it from him. Ran great after I rebuilt top end.
Car did 140 on the turnpike & ran great. once or twice while giving moderate to high throttle CEL would flash and I pulled P0300 as a pending code. Problem stopped after 2 days. last week after 4 hrs of idling(don't ask) started misfiring and CEL flashes constantly P0301 The misfire seems worse at idle and low speed. Car will get to highway speed but has bad pickup. This is what I?ve done/checked New iridium plugs Plug wires 4.5 ohms Coil pack is good and producing enough spark at each wire MAF sensor cleaned Cyl 1 compression good all injectors are clicking and when disconnected cause appropriate CEL error code Brought car to VW dealer for diagnosis VAG COM shows multiple misfire on cyl 1 Mechanic confirmed all the steps I took and components tested ok. He tried new coil pack, new plug and wire for cyl 1 and no change.
