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.

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
Passat (B5) :: 2001 - Misfire On Cylinder 1 And 2
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.

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?

Passat (B5) :: Cylinder 2 Misfire / Does Not Move With Coil?
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?
View 8 RepliesPassat (B5) :: Multiple Cylinder Misfire Randomly
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?

View 6 RepliesPassat (B5) :: Random And Cylinder 1 Misfire At Idle And Low RPM
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.....
View 9 RepliesPassat (B5) :: 1.8T - Rough Idle / CEL Came On / Misfire On Cylinder 4 And 2
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. ??
View 6 RepliesPassat (B6) :: New Plugs / Coils - Misfire On Cylinder 2 Or 4
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.
Ford :: 1997 - Cylinder 1 And 6 Not Firing?
Diagnostic says 1 and 6 are not firing. Car runs rough slightly. I think one of them is intermittently firing the other maybe not at all.
Possible causes according to diagnostic:
coil, plugs, injector, vacuum leak, wires (From memory)
Gas mileage is excellent. This makes me think its injectors. Failing plugs or wires would cause massive gas loss through misfiring cylinder.
Just bought this car. The seller said the wires and plugs are new. I will inspect tomorrow when I do the brakes.
Assuming they were replaced it leaves coil, vacuum or injectors.
Passat (B5) :: V6 Check Engine Light - Misfire In Cylinder 4
I'll try to break this down as best I can. I went to my mechanic this am with a check engine light. My suspicion is 02 sensors. This was confirmed as a problem area, but separate they said I had a spuratic misfire in cylinder 4. With that info, i pulled the plug to inspect (I had just installed new ngks in it and they have 18,000K on em.
I put beldon wires on about 8k ago.) plug looked to be normal, but there was definitely a puddle of oil from the valve cover leaking. Oil went into the cylinder head but I didn't really think that was an issue. Nothing abnormal jumped out at me so I reinstalled plug and checked all wire connections at both ends and called it a day.
Then I drove it. Check engine light flashing. Major performance stutters, etc. I drove it for about 20 miles and hoped it was just the oil raising hell in there and it would burn off eventually. It hasn't gone away yet. Maybe coil pack. Can the single portions of that pack be replaced, all i see them sell is the full three as a unit.
Passat (B6) :: Engine Running Rough And CEL On - Misfire On Cylinder 2 And 4
I'm having an issue with a 2008 Passat 2.0T. Engine ran rough one day and check engine light came on! I get the VagCom out, scan the ECU and get misfire on cylinder #2 and #4. Car has 109 000km. Plugs were never changed so I order some new OE Bosch platinum iridium plugs. Go for test drive after having change the plugs and I still get misfire on both cylinder number 2 and 4.
I know coil on plug are prone to be weak on those engines so I go ahead and order 4 new coils which are pretty low cost which is good. Once install on the car I go again on a test drive. car ran really smooth and no check engine light came on. I said fine! I fixed the problem only to discover the day after that the CEL decide to come back on I scan again and this time only get misfire on cyl #2 with fault frequency of 39.
I suspect my injector to be bad but before I decide to remove the intake manifold and spend another 2-300$ in parts. Any way to test my injector with VagCom in order to see if that really is my problem. Also heard the PCV could be a problem but i hardly doubt it would throw a fauly code on just one cylinder.
Passat (B6) :: P0303 (misfire Cylinder 3) / P0299 (underboost)
I've got two error codes that are persistent. The underboost code will be fixed (I HOPE) when I replace the diverter valve which is currently sitting in my trunk.
But I'm getting a persistently intermittent P0303.
Here's whats going on:
-Some mornings, I can start the car and get a very minor rough idle, it seems to miss very occasionally.
-Some mornings, PERFECT Idle.
-Some mornings, Flashing CEL, very rough idle, P0303.
It seems to go away after about 30 seconds to a minute regardless. Sometimes ver minor rough idle comes back on hot start, but not enough to set a code.
What I've done:
-Replace spark plugs. (all 4)
-Replace offending coil with brand new one.
Still having the same issues!
Can these two codes be related, and once I replace the diverter valve, things will be better?
Passat (B5) :: 2004 1.8t Running Rough With CEL On - Misfire On Cylinder 1

View 4 RepliesPassat (B5) :: Cylinder 2 Misfire On Cold Start Ignition
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??
