Passat (B5) :: Cylinder 2 Misfire On Cold Start Ignition
Mar 12, 2012
I get a cold start ignition miss on cyl #2, then goes away (with a little revving), car then runs 100%. No problems during hot re-start. 2005 1.8T AWM. I replaced all four plugs (NGK OEM), all four coils (OEM latest rev), Coolant temp sensor (temp gauge was flaky). No other codes other than Cyl#2 miss and Random Cyl miss. Could I have a leaking (fuel dribbles out) injector on Cyl #2, causing a too-rich misfire when the car is cold started??

My 2010 gti has a p30030 misfire cylinder 3 only on cold starts. Swapped plugs and coil packs, still only on 3. Took a look inside every cylinder and found that there was some oil in the cylinder only cylinder 3. So much blow by that it kind of collected in the cylinder? Carbon cleaning needed?

I have an 07 kia rio, I had a misfire in the 3rd ignition cylinder. When I opened it it had oil in it. So I cleaned it out and put a new spark plug in it and change to a thicker oil. A few hour later wet to drive it and after five minute the car shut down. When I was able to get it to turn on, it started to knock. I got it check and said misfire in the 1st cylinder, So I changed out all the ignition coil one by one it didn't work till I got to the last one, the knock went away for a few minutes then came back. So I put the originals back it and the knock is gone but it still misfiring with the check engine light flashing or staying light.

Bought a 2006 (later production) with 25,000 miles over the weekend. Couldn't pass up the price and the warranty (1 year left + CPO). Picked up the car Saturday at noon..... had to drive to DC for business and the CEL came on when I turned on the car this morning. I researched at lunch that it could be a cold start misfire but I am already pretty heated about this. When I get home tonight I am going to plug it in to my OBDII scanner and see what I can pull. If it is something bad.... I am giving it back to the dealership.

2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?

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....

I am having a misfire code on the #1 cylinder. Its not bad but I really want to nip it in the butt before it goes out completely. I was told to try and get some of the older style coilpacks that bolt on and go with them. Can I put them on my 03 passat 1.8t.

Well I started her up and started driving her again and I got a cel! (remind you it sat all winter just got started up!) so check the cel and it says cylinder 1 misfire! ok, check spark plug gap and change # one coil to # two and two to one! everything seems fine! well get the same cel and misfire BUT this time says its cylinder 3???? so what coil packs do i change and what do i keep? the #1 and #3 were changed 18 months ago under recall! havent had any misfire since i cleared the last cel! Just change all 4? gap is at .032 on all 4 also! wires are all good and harnesses are perfect! are they just going bad or just a hickup from sitting?

As the title states... 2003 Passat 1.8T. The car was running fine. Had a new timing belt installed. The Check Engine light now continues to come on for Cyl #1 misfire. Attempts to fix so far include:
1) New plugs
2) New coils
3) New injectors
4) new cam and crank sensors

I have my timing belt and oil pump replaced and after 2 days the car was misfiring. Had the throttle body clean and reprogramed and still the same issue. run all test and its ok. What the issue will be. I was told it can be the ICM but the mechanic says there is no way to test it.

my dad has a 2001 Passat and he recently had his check engine light come on. We had it checked by a guy who owns a tester (snap on) and it comes up with a misfire fault on cyl #2. Wire looks good, I didn't have tools with me so I couldn't take a plug out, but do you think it could be a bad spark plug? Bad coil? Car has 89K on it.

I have a misfire on cyl 3, what is the firing sequence, changed plugs which didn't solve problem... so I'm going to try coil pack.

Today I started up my 2013 Passat SEL up and it started shaking and idling very strange. A few seconds later I had a flashing CEL so I decided to turn her off. I waited about 5 minutes (after cursing for about 4.5 if those minutes) and tried again. This time the car started and everything was fine, no CEL, no other issues. I drove for about 10 miles, shut off the engine and re-started about 5 more times with no issues.
I just had the car in for the 50K mile service at VW and everything checked out ok. I copied the VAGCON report below and I also sent it to my service manager to get his opinion. What I should do?

My brother has a 98 turbo passat which is reporting misfire on cylinder #2. We swapped the coils between cylinder #2 and each one of the other cylinders and the problem did not move, making me beleive the coil is not at fault. What else should we check?

The Problem: Multiple Cylinder Random Misfire, Misfire on Cyl 2 and Cyl 3 codes. Runs fine on highway after first start in the am. Begins to misfire badly/throw code within 1 mile after exiting highway driving and starting "stop and go" city driving
The Car: 1999 VW Passat 1.8t "AEB" engine code
192,xxx miles. Greedspeed/Neuspeed ECU. All else is stock
****ICM module replaced less than 1000 miles ago due to misfire/similar problem. All was fine until now*****
Compression tested (cyl 1-4): 155lbs, 150lbs, 145lbs, 155lbs
Repairs/troubleshooting tried already:
Swapped cyl 2 and 3 coils for cyl 1 and 4. Result: problem remains / same error codes (cyl 2 and 3 misfire / random misfire)
Swapped cyl 2 and 3 injectors for cyl 1 and 4. Result: no change, problem remains
Tech is suggesting fuel system cleaning (to eliminate any carbon deposits in cylinders and clean injectors). Then look at replacing injectors if problem persists. Could I have another bad ICM?

1999 Passat 2.8L. New coil pack assembly, wires, plugs, valve cover gasket(oil in plug holes). Misfire at idle and low rpm. Driving at higher rpm's misfire seems to go away. Codes are random misfire and cyl 1 misfire. Need to know if I would get an injector code if a fault or If that motor has problem with faulty cams or springs or any other common problems. I am going to do a compression check this weekend I'll update that info.....

So every once in a while I would start my car and get a rough idle but not too bad. I got a cel after a few times of this happening. I had a misfire on 1 and 4 and possible misfire on 2. It was ok for a a couple days. But during the last few days I'll start it up and it's fine. But then if I shut it off and restart it will have a rough idle again. Also today I got gas and then it rough idled and when I would shift or put it in neutral the rpm would stay up and drop slowly down. Like if I shifted gears I could almost do it without the rpms dropping at all. I've got 110k. ??

Replaced plugs and coils after I got a misfire on cylinder 2. (cheap made in china coil packs off of autoparts warehouse)
Also, plugs had 30k miles on them with original packs. Got it again.
Replaced coil on cylinder 2. Got it again.
Bought Denso double platinums. Got it again.
Moved coil packs around. Misfire on cylinder 4.
Checked plugs, good dry non corroded. Its always 2 or 4.. not 1 or 3
Slow drive with less than 30% gas pedal action it runs "ok". If I go uphill or need to step on it, not happening. Bucks like a mule.
I dont think its the fuel injector... Ordered the red audi packs off europaparts. Might need to check connections. what do i do?
I've been also reading that it could be the cam follower. I'm willing to check it and then force the dealer to fix it under the extended warranty, but if its broken I cant put it back in. The dealer is 50 miles from me.
It happened a morning I was out of gas and used .... regular! But did put in super right after that. I had spare regular gas in a container (fresh) for the generator.
Then used fuel additives. I have also been using fuel additives every other fill up just to protect injectors. I know it wont do anything other than that because of direct injection.

I have a 98 1.8T passat. The number one cylinder won't fire, according to my checks, the ignition coil is not being activated by the CPU, (no current at the connector only ground) what could cause this problem. Any way to check the crank or cam sensor.
