Passat (B5) :: Flashing Check Engine Light / Codes P0300 And P0301
Aug 18, 2007
This morning I started my car and it was idling a little rough. The the Check Engine light began flashing - I immediately turned off the car and consulted this forum and my father the mechanic. After talking with my Dad and telling him that the car had sat for a week, he thought the issue was probably NOT the catalytic converter and thought it was probably related to the car sitting and possibly getting moisture in the gas. I started the car again (the roughness at idle seemed to have gone away) but the check engine light/malfunction indicator light (MIL) did not flash, it did come back on after a few seconds, but as a solid light . And as we've all read, it's OK to drive with a solid MIL.
I took the car over to Autozone and had the codes checked - P0300 (multiple cylinder miss fire) and P0301 (cylinder 1 misfire). I asked them to clear the codes. I has just put in new NGK spark plugs last month, so I didn't think it would be the plugs. I looked at a new coil pack for one of the cylinders. I decided to see if clearing the codes alone would work and drove home. No issues so far, no MIL, no rough idle, no hesitation (fingers crossed).
When I called the stearleship - they recommended I have the car towed, but would not speculate as to what the flashing MIL could be (catalytic converter or bad coil pack(s))...

i have a 01 passat with a v6 in it on 4 motion and im having an issue with soem mis-firing
i pulled the codes. P0300 P0301 P0302 and P0303 which are all saying that there are missfires in cylander 1,2 and 3 and random miss fires.
im also getting a P0340 which is cam sensor A or the right hand bank. problem is i just replaced the cam sensor and when the motor got warm, the code came back. I was told by the previous owner that the car needed a Coolant Temp Sensor....can this be the cause of my mis-fire issue? hear me out.... it only happens when the car is warm so im thinking that the car is warm but the ecu thinks its cold cause its not getting a good signal from the CTS. thus its either advancing the timing as if the motor is cold and cuasing a miss fire or something along those lines. any thoughts?

Just got a 98 f150 w/ 5.4 4x4 excab. It idles fine but under light accleration. It starts bucking and missing bad, if I step on it, it down shifts and accelerates fine. If I try to maintain one speed it misses bad. It is not throwing any codes right now. The check engine light did come on for like a minute but went back off before I could have it read. I hooked up a scanner just to see if any codes were stored and got p0300 and p0301. I am going to clean the MAF and check for vacuum leaks. I hear the rear plug and coils can get water in them causing similar problems.

I know it is a random cylinder misfire code however I started my car in the morning and it was fine I moved it and put it back in my driveway. I started it up later and waited for it to heat up i came back outside 10 min later and my check engine light was flashing and my car was shaking like crazy you could tell the engine was misfiring like crazy. I had under a quarter of a tank but not empty yet. I shut it off and turned it back on and it was still doing it. I drove the mile to the gas station the way it was.
Under partial throttle it was revving to 4500 and over 5, had to let of throttle to make the car shift up a gear. I filled up and started the car again performed fine after that however the check engine light was solid now and still on. I went to my local mechanic and he read that code P0300. I changed my spark plugs that day and they were crap the original spark plugs I have 65,xxx on my car now. Car is smooth now. I cleared check engine when i saw him first and it did not come back on all day even before i changed the spark plugs later that night. Why my light was flashing and why my car was acting like that till i filled up?

My 2004 Cadillac CTS 3.6L started running rough, check engine light flashed on and off. Codes P0300 and P0303. The car has about 119000 miles. Could this just be the plugs? The car has been running fine up to today.

I have a 2001 Passat 1.8 Turbo engine trim is AUG. My car is acting funny since yesterday. When i start my car it idles rough and CEL start flashing but as soon as i drive at like 10-15 MPH speed it becomes smooth and CEL stops blinking. I took my car to autozone and have it scanned got P0340 P0300 P0301 and P0302. It means random misfire and misfire in cylinder 1 and 2. I am not getting the misfire code for cylinder 3AND 4.
I swap coil boot 1,2 with 3 and 4. But misfire didn't move with cylinder. So i waited whole night reset CEL and swap coil 1 with 4 and 2 with 3. Have i scanned again not i am getting P0300 = random misfire and P0302 = misfire in cylinder 2. I didn't get P0301 this time.

2002 Passat 1.8T
Backstory. The P0411 code shes had for quite some time. I think probably 4 years maybe. Just never did anything about it because I guess they are expensive to fix. Thats the SAIP and combi valve correct? Anyway to remove all the emissions stuff and get the codes deleted?
So, about 3 weeks ago, maybe a little longer i cleaned her engine bay, replaced a few vacuum lines because the shop she took it to last year did a terrible job. Mind you, they did a head gasket, timing belt and some other minor things while they were in there. And they couldn't take the time you run new vacuum lines, since they just cut the originals and used a bunch of t fittings to "solve" the problem.
Anyway, i replaced the lines and it seemed to run better at idle, still had a little mis at idle but ran smooth at speed. I also did an oil change, put some fuel injector cleaner in it, put some seafoam in the oil, and cleaned the engine bay thoroughly. I did it properly and took all the plastics off, cleaned them, scrubbed the bay and used an air hose to get rid of the excess water. Left in a nice state. Ran smoother, looked better, so on and so forth.
Fast forward to last week, and she mentions to me her car isnt running right. Its sputtering, hesitates, running rough, exhaust is puttering, and it used up a lot of gas. She parked it for a few days, and i came down to look at it. Mind you, i don't have a code reader. So I looked at it blindly thinking it had an ignition issue. Nothing could have changed that quick since i looked at it.
So, today we got one coil(just in case ones bad), and 4 new plugs (Autolite Iridiums). Replaced and gaped the plugs to .030, torqued to 23 ft/lbs and started the car. Seemed to run a bit better, but subsided quickly. I then pulled each coil harness plug to make sure it would misfire on each cylinder and it did. So, new plugs and the coils checked out. Time to get its codes read.
Took it to the Pepboys and the codes it came back with were the P0011, P300, P0301-3. Cleared the codes and they came back nearly immediately. I had the dreaded P0011 code. The misfire codes im guessing were from the coils being pulled on each one, and also due to the P0011. Now i read a lot of threads about the P0011 and how its usually not the camshaft position sensor. However, i pulled the plug on that while the car was running and nothing changed. So i thought it could be the CPS. Changed that out and still nothing.....

A few days ago my "Check VSC" warning came on along with the check engine and traction lights being on. I left my car in a parking garage for a week when I was on vacation and the lights came on once I started the car after getting back from my trip.
I have had the "Check VSC" warning before and I fixed it by replacing my gas cap. My gas cap seems fine this time around so I got my codes scanned and the only one that came up was P0300. Having this issue with the 2007 Lexus GS 350? I still feel like it's my gas cap because I bought a cheap replacement last time around.

Let me start with some background. 2001 B5.5 Passat Sedan 1.8T 5spd Completely Stock 156,000 miles. So, tonight i head for the grocery store about 5 minutes up the street. I get about half way there, when I notice that the check engine light is flashing. I ease off the gas, and coax it to the next light. At the light, the car feels like it might stall out, and the car seems to shudder, and I notice that the shudder is connected to the RPM of the motor. Meaning, if i rev the motor the shudder gets faster.
I manage to coax the car home to my driveway, and I leave it in a position easy to be towed. So, i figure that I will leave the car running, and look under the hood, but as soon as I open the drivers door, i can smell something burning/smoldering. I shut off the engine, and carefully open the hood. I find no smoke or fire, but I see that the downpipe (or whatever pipe the exhaust coming from the turbo leaves through) is glowing red hot.
I am not sure what happened. The car gave no other obvious symptoms. The other things I should mention though, are that I change my own oil. Always Mobil 1 with a Audi or at least german filter. However, my father was the original owner, and for the first 60k he used conventional oil. The turbo has always been strong, and seemed to deliver full boost. I do not know if it is still boosting in light of recent events.
For the last few weeks, the check engine light has been on and off. My mechanic scanned it a few times, and told me that it was the "Air Injection Pump Code". My understanding is that this system basically divers exhaust gas into the Cat when the car is warming up. If its not working properly, then it is just a emission problem.
I should also mention, that the car has recently been leaking a little bit of water when there is a hard rain storm. On Saturday, I took the rain tray cover off, checked the Pollen Filter, and removed the battery in order to clear out the drain plugs under the battery tray, and the brake master cylinder. As I write this, I begin to wonder if its possible that something just went very wrong with the Air Injection System.

My 1999 Passat 1.8T (AEB engine) with 120,000 miles has run very well lately.............except for a recent problem. I drove 150 miles on southern California freeways, parked the car for an hour, then started it again. There was a distinct miss and the check engine light began flashing. I turned it off, let it sit for a couple hours, then plugged in a code reader. There were two codes, both the same - P-0302, "Cylinder #2 misfire". I pulled the cover off the engine, wiggled the wiring to the #2 coil, cleared the codes and started it up. There was no miss, maybe there was a little corrosion on the electrical connection?? I know there was a recall on the coils, but my car was too old to participate in the recall. Which it is - bad connection, bad coil, or something else? Or a way to diagnose it further?

Check engine light came on yesterday evening. Advance read the codes as P0100 and P0171. The guy said something that it may be related to the mass air flow sensor. The car seems to run fine.

Ok so we have yet again the engine light on...we did a test and we have the codes P2004 and P0642. What can it be the problem this time??? what can cause this codes and is it expensive to fix? We just fix the care a couple of weeks ago( codes P0507 and P0171) and we are sooo tired of having problems.

The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.

I was just driving and the engine check light appeared. The screen says Emission workshop. its a 2001 B5 passat V6 Manual. I used a code reader and it read P1120 and P0154. Are these codes serious? Can I still drive around? What should I do?

I never had a single problem with that great car, now at 164,000 km, but got my first check engine warnings last friday, with the VSC OFF flashing, as well as the stabilitrak and check engine signals being lit. The car was still running fine, so I disconnected the battery this weekend and erased the codes. But this morning (2 days only later), the warnings are back. I went to a local garage and they retrieved the following codes: P043F, PO43E, P2402, P2419, P2401 and P2402. What do I do with this?

Check engine light came on. Codes are P0300, P0302, P0304. Plugs were previously changed. Plugs look good. Changed both coils. Light still one. Injectors also previously cleaned. What else should we check for? Valves hanging? Anything else to check for?

Mystery issue with my 2001 Accent GSI (5-speed manual, 1.6 L). I'm getting a P0300 error code and the Check Engine light (the light is like an old friend, I miss it when it's not on). This happened four months ago and I replaced the ignition coil - seemed to fix things - but now the light and the error is back with a vengeance. Car stumbles and runs rough. Changed the plugs and plug wires, but no difference.
BTW, there's a small pin hole in the upper part of the gas tank (just enough to give it a gassy smell when the tank is full) but I don't think the hole would be big enough at this stage to cause the check engine light to come on in the same way it does if you leave the gas cap off or loose.

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....
