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).
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.
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 RepliesWe 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).
Car dumbie back again with another question.The diagnostic for my check engine light indicates numerous cold start misfire codes. The cylinders are OK. That was checked during the diagnostic.The fuel intake is carboned up. It is recommended that I clean the intake manifold. Does this mean cleaning the fuel injectors, the throttle body or both? 2006 Passat VW....
View 1 RepliesThe 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.
View 6 RepliesI have had a check engine light on in my car for a while now. I am pretty sure that it deals with the disconnection of the vacuum servo that controls the intake manifold's flaps that designate which track the air takes through the manifold. It has been running fine like this for a while under the assumption that because the performance of the vehicle hasn't changed, there is no need for immediate repair.
Here is my new problem which I am trying to determine if it has to do with the above issue. Over the past few days my car has been giving me EPC and ASR lights along with switching to back-up power. I have been on expressways driving 80, i have been going around corners doing less than 20, and it has happened everywhere in between. Keep in mind that when it happens i slip my car into neutral, pull over, and reboot. After that everything is fine for a short while. I stopped at Auto Zone to get a diagnostic, and for some reason, which i did not feel like questioning due to the way the autozone employee was mentally equipped, they did not give me codes, but descriptions.
(1) Camshaft Positioning Sensor Fault A Bank 1
(2) Camshaft Positioning Sensor Fault A Bank 2
(3) PCM Processor Fault
(4) Running too lean on Bank 1
(5) Running too lean on bank 2.
These are the descriptions for the 5 fault codes. I am planning on stopping back today and getting the proper codes. But would like to get some opinions in the mean time. I've check fuses and relays pertaining to this issue and all have tested ok. Nothing is leaking from my engine and nothing is visibly damaged, except for the vacuum servo arm which is broken (see above paragraph). I feel like the issue is with the ECM (PCM, PCM, ECU, whatever).
Another interesting thing is that when i operate my car using the cruise control, there are no issues what so ever. Possibly an issue with the throttle or its many components?
My truck's been having an occasional hard start, meaning the engine cranks strong but it fails to catch and then sputters. The 2nd start attempt usually fires up with no issues and then runs perfectly otherwise.
MPG's haven't changed, fuel filter was changed 15K ago. Air filter is clean. Plugs were changed about 10K ago. I always use Shell/Chevron gas. MAF sensor looked clean when I took it out so I didn't do anything to it.
This is starting to happen more frequently, maybe once every few weeks and I get a feeling it's the start of something. I've found myself waiting a few seconds for the fuel pressure gauge to come up before turning the key to start reliably. In the past, I could simply flick the key and it fires up the first time.
I see posts talking about the fuel pump module above the spare tire. What are symptoms of that going bad? Any pending codes that might be stored?
I'm about to get myself a scanner since I need one sooner or later. Which specific PID's to check while debugging this?
I have 01 passat, it runs fine, except check engine light is on. When I turn AC on the engine beginnings to work funny, RPMs jumping up and down, feel like engine doesn't get enough air (or gets too much). I was told to replace ignition coils. I replaced them all but the problem didn't go away. Even actually one of the coils pups up a little bit all the time.
View 1 RepliesFriday, May 13 I brought my car to the shop because the Check Engine light came on and the engine started loosing power. $540 later they had replaced both O2 sensors. A day later the light was back on. Brought the car back on Monday and they replaced one of the sensors that was defective according to them. One day later the light was back on. Brought the car back on Wednesday and they replaced the sensor again, telling me the brand was not compatible with my car. One day later night the light came back on. Brought the car back in Friday May 20 in the morning and they have my car since. They can't figure out whats wrong. A week before all that happed I had an oil leak and they replaced the oil filter and a seal. Could that be it?

View 19 RepliesI 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?
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 RepliesI have an 05 diesel. I have noticed the last 3 days I needed to crank it slightly longer to start it and it takes a second before ideling normally. It usually fires right up and jumps to life. Today i drive about 45 minutes. Stoped for about 30 minutes and shortly after I started it back up the check engine light came on. Will the Ex flash you the codes or do you have to have a reader? Thought I would try Autozone tomorrow but not sure if they read deisel codes or not. I was suspecting maybe glow plugs but who knows at this point. It seems to be running fine and I checked all fluids.
View 13 Replies2004 Golf, manual transmission. The yellow check engine light comes on when it's driven on the highway for more than 10 miles or so (60-70 mph).
The light goes off on it's own after about 36 hours of suburb driving - 1-2 miles at a time on suburb roads, lots of lights and not going over 40 mph.
1) Why the light is coming on? No other signs of trouble occur - oil looks good, temp stays fine, no smells, etc.
2) Why the light goes off after 4-6 miles/36hours?
a 2011 jetta. brake pedal is hard no pumping action. The car show check engine. The idle is not smooth.
View 2 RepliesI 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?
View 6 RepliesAnother month and another problem to be resolved. Here goes: The 2001 Passat 1.8T has had a hard life in the past year. The specifics are listed in previous posts. Most recently, the radiator was replaced because the engine was overheating again. The car has been leaking fluid ever since but it is not radiator fluid. Yesterday, I took a look at the oil and found tan gunk mixed in with the oil. I must admit that I had concerns after the fact about the shop that did the last oil change. Is it possible for mechanic to screw up the head gasket while replacing the radiator? It was fine before the repair. Is there another source to look for the seepage into the oil? Basically, the question is - Is the car destined for the graveyard because of this?
View 9 Replies2001 passat, 1.8, manual 140K. Last Wednesday I went to drive south, and i turned the key. The engine cranked but it didn't start. After trying for a few minutes, and the engine stumbling after a few times, the engine started. RPMs were low, but after a few seconds everything was fine. The outside temp was probably 15-20f.
Over the next few days the car sat, except for once where I moved the car (outside temp was 35+), and it started right up. As soon as the temperature dropped to 18 or so, it did the same thing, crank and crank then start. I dont remember if it was then or wednesday when I got a CEL while trying to start the car. I checked it and got a P0321. Cleared it and havent seen it since.
Fast forward to sunday, morning was the same thing, about 10 tries until the engine started. I got a jump start in the afternoon thinking it was the battery. It started right up (temp was 30+?). The next day I decided to roll start it, started right up (temp was 15?).
I replaced the battery monday thinking that was the cause. But everything is the same, when its cold I have to crank and crank. Once the car is running, the RPMs are low. If I give it gas, it stalls. Once the RPMs come up, if I stop the engine, it starts right back up. Thinking it is a fuel problem, I played with the fuse.
Granted, the engine was warm when I did this. Engine running. Pull fuse out, after a few seconds engine stalls. Try to start, no go. Put fuse back in, engine starts right up on first try. So now we go back the CEL. I thought at first it was just a side effect of cranking and cranking the engine. But now I think there might be a problem with a sensor, engine speed sensor maybe? Coolant? crank?
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 RepliesMy daughter has a 03 Accent that within the past week will not start at certain times. Some times it will some times it wont. It always cranks but doesn't catch. If she tries to start the car and it cranks, but doesn't catch, if you wait 15 -20 minutes, or longer, it will turn over and run fine. We are thinking crank position sensor or possibly fuel pump...
