Jetta - Volkswagen :: 2001 - Check Engine Light Came On For Mass Airflow Sensor

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?

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?

Santa FE SM (2001-06) :: 2002 V6 AWD Check Engine Light Stays On After Replacing ECM

My 2002 Hyundai Santa Fe 2.7L V6 AWD failed to start a week ago. After towing to my neighborhood repair shop, it was diagnosed as a faulty ECM based on code P560 (System Voltage Problem). They replaced the ECM (along with relay) with a used one with the exact same part#. After that, the car was started and run OK but Check Engine Light stays on all the time. The codes displayed are:

P1529 TCU MIL Request Signal
P0501 VSS Range Performance

I was told that this is caused by the fact that each ECM is VIN/PIN locked. The replacing ECM was used in another car before and was locked with a different VIN thus cannot communicate with some components of the current car.

My questions are:

Can this used ECM be unlocked and relocked with a new VIN/PIN? If so, does it require the previous VIN/PIN to unlock? Most likely the previous VIN/PIN is no longer available.

Does this service require the presence of the car or can it be done with the ECM alone? Do keys need to be re-registered? The car starts fine currently.

Chevrolet - S-10 :: 2001 - Check Gauges Light Stays On And Oil Pressure Gauge Stays At 0

I have a 2001 Chevy S10 4.3L. The CHECK GAUGES light stays on, and the oil pressure gauge stays at 0. The oil is full, and the engine runs and sounds fine. I drove it about 5 miles with no change. Up until now, the gauge has worked normally. Could it be the sending unit?

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?

Jetta - Volkswagen :: 1994 Airbag Alarm Light Stays On

[URL]......................................................................

After I could not figure why I was having the alarm light I drove the car to a mechanic, explained my sleepless nights and many hours of problem analysis, and then the mechanic took his code reader, connected to the OBD car port, made a few clicks, and charged me $45 and then sent me off. The alarm light has not been back since - it blinks as expected when I start the car.

On my further research I have found that VW airbag light will come on if you check airbag with your ghetto OBD code reader - exactly what I had read! It registers "high resistance", and must be reset by someone with a qualified code reader!

Passat - Volkswagen :: 2001 V6 Cranks But Does Not Catch / EPC And Check Engine Light Come On

Recently I bought an 01 Passat with a V6. Intermittently, when I go to start it, it cranks and cranks and doesn't catch. When this happens, the EPC and check engine light come on.

Other than that it is a fine car, I'm the second owner, and it was thoroughly maintained at VW dealerships and specialist. Recently there was a new oil pan and starter put in (w/in a month--previous owners).

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.

Jetta - Volkswagen - Sensors :: 2001 - Engine Light On - Sputtering / Bucking

I drive a 2001 VW Jetta and have had many issues with this car but have had this particular issue many times. It starts when all of a sudden my car feels like it's going to stall when idling. When I go to drive it in this state the car has difficulty excelerating, bucking and sputtering (like the engine isn't getting enough fuel) and the engine light comes on. I have taken it to many shops and they usually replace an oxygen sensor saying that it is clogged etc. I have also had a couple of tune-ups because of it but after about a year the issue comes back and I shell out more money. I was told by one mechanic to use only super gasoline and that it should prevent it from happening again which I did and it held it off from happening again to about a year and a half but now it's back.

Golf IV / Jetta IV :: 2001 Mk4 - Check Engine Light Flashing

So my gf's check engine light on her 01 Golf flashes once in a while, and it misfires. But the thing is, it doesn't stay on, and it's once in a while (like once or twice a week). She has new spark plugs, and new wires. I have a feeling it's the coil pack, but I really don't know if it needs to be replaced until the check engine light actually stays on.

Golf IV / Jetta IV :: 2001 GTI VR6 - Check Engine Light Flashing

Just a few days ago I was driving and I noticed as I went over 35 mph my car would stutter and the check engine light would start flashing. And when I slowed back down the car drove fine. I'm wondering what the problem could be? Feels like the car is losing power. Car is currently at 119k miles.

Golf IV / Jetta IV :: 2001 - Light Stays On Even When The Key Is Off

Even when the key is off this light is on. The rear defrosters are not getting hot, and when you turn the car on and use the defrosters the light will brighten. It happened to my car while it was sitting in the school parking lot.

The cause of this problem I assume is a short in the wires going from the c pillar to the hatch.

[URL]................

I just put the rubber cover back on them and the light turned off. Insulation on some of the wires was cracked and falling off. I will fix the wires with either electrical tape or new wires depending on the condition when I am able to do further inspection

Jetta - Volkswagen :: Check Engine Code P0106 / Clean Throttle Valve

VW Jetta SE 2.5L... Took my car to the dealer for a check engine light, the code came back P0106 which states I need my throttle valve cleaned and the dealer also said I need my brake vacuum pump replaced.. Do these go hand in hand? How should I proceed with the dealer? I have only 60,000 miles on my vehicle was there a recall on this issue? The dealer already updated the software in the technical bulletin.

Golf IV / Jetta IV :: 2001 1.8t Stopped Running - Check Engine Light Blinking Because Of Misfire

So last Thursday I started my car up in the blistering cold and it ran fine for about a minute and started to misfire so I shut it off. It hasn't ran since. When that happened the check engine light was blinking because of the misfire. I didn't have a code reader at the time to read it. now that I got a code reader the damn thing isn't throwing any codes. it spits and sputters sometimes. I've had no previous problems with the car. Thinking It might be a weak fuel pump or bad coils and in not sure how to test them.

Jetta - Volkswagen :: 2001 - When Come To A Stop Light The Car Will Die

Experiencing very weird electrical issues with my 2001 Wolsfburg edition Jetta 1.8T. Sometimes when I come to a stop light the car will die. I'll turn the key and here "clicks" and see flickering dashboard items. I've found if I power the locks up and down several times eventually the electric system engages again, and I can start the vehicle. Before the system engages, the locks will only slide up/down slowly or not fully. I encounter these electric issues moreso during cold & wet weather. To avoid having the car die, I'll keep my engine revved up at stoplights. I've sometimes experienced other random electric issues. For example, while driving on the freeway last week I turned on my headlights. I heard 3 loud beeps. I think a couple dashboard lights came on (not the check engine). Sometimes these beeps/lights occur just during normal driving, and almost always when I come to the next stop the car then dies. Battery has been tested and is fine. Ignition coil recall performed, still has issues.

Toyota - Avalon :: Check Engine Light Stays On

The "Check Engine Light" is on. When I brought it in for the annual inspection (NY), the diagnosis was "lean fuel mixture". The fuel filter was replaced (the car has over 110,000 miles on it), and some adjustments were made in the computer, or the sensors (I don't remember which). It was found that one adjustment was effective at low speeds, and the other one was necessary for 2000 RPM. A valve cover gasket was replaced because of an oil leak, but I don't see how this could have contributed to the problem. I drove it for about 10 miles and the light went on again. What the cause might be?
