vs
Ignition coil OEM Volkswagen or HUCO
Reviews
I had the same deal, but none of the similar error codes. Verdict: it's probably your ignition coil. Overtime they crack SOOOOO SLIGHTLY that they let in moisture and you're boned. I snagged the Huco cheap one, been fixed ever since. I finally saw the cracks in the old one when I took it off and it was easy to change. I have a 1997 Golf GTI 2.0 8v
Pros: easy to change, fixed issue
Cons: cracks let in moisture

Volkswagen Golf
I got it. All good now. I swapped a Meyle coil (probably original right?) Out for or a used known good Huco. Knock at idle is GONE and she reves right up!
Pros: Knock at idle GONE
Vehicle:
Volkswagen Jetta
as the op stated, the car sounded completrely different. there was no hesitation, idle changes, vac changes. the car also accelerated a lot smoother as well. it was easier to start from a stop and the engine felt stronger. i didnt believe this at first myself so i threw them on my buddies heavily modded a4 that had an ignition problem between 4-5k rpm and the sound went away with these coils. his car also performed much better as well.
Pros: smoother acceleration, stronger engine
Cons: Fitment issues

my tach was acting up when i first got the car, I cleaned all the connections going to the coil when i replaced the coil and that fixed it.
Pros: cleaning fixed the issue
Cons: tach was acting up

Changed the plugs, and while changing them noticed that there was a little charring in two of the coil paks seating surface where the spark plug tip sits...after changing the plugs the car still felt like ****. Ran to Advanced....and they showed 2 cylinders not firing good, needless to say they only stocked one coil pak. I replaced it and the car ran like a champ.
Pros: car ran like a champ
Cons: car still felt like ****

My wife's 2000 Cabrio started having this same set of symptoms. Replaced coil, plugs, plug wires, cap and rotor not that long ago. Coil was indeed cracked, but the symptoms persist.
Cons: symptoms persist

Everyone swears the stock coils are great for 800hp because force fed did it. I don't care, the coils suck and always have. I always had random misfires here of there even when new, and I could never run the plug gap I run now with push downs or bolt downs on a stock car even without serious hesitation and enough to increment the misfire counter. This 190k mile Jetta did this also and I thought maybe carbon fouled plugs or a dying coil. Now it pulls 20 inches of vacuum with a rock solid needle at idle no bouncing, no hesitation. The car sounds absolutely different at idle, fresh plugs and a .040 gap, no other change but the coils and fersh plugs. It sounds throatier and crisper with the larger gap too.
Pros: throatier sound, crisper sound
Cons: random misfires, hesitation

I used to use the HUCO brand single coil on my old 8V and it would fail every year.... My parts supplier now only sells HUCO when they can't get the BERU units. I have a BERU on my VR and def a better quality piece. I think I went through 4 coils in 5yrs with my old 8V... eventually I kept one ready in the car "just in case"
Pros: Beru better quality
Cons: fails every year
Yep. The codes don't lie, the coil pack is bad. I swapped it into my wifes 04' and the CEL/ misfire was right there with it. The guy bought it somewhere local but doesn't have the receipt/ record, so he's out $175.
Pros: codes don't lie
Cons: coil pack is bad

Yep, guess it's common, but mine just caused a smoking fire under the hood! As mentioned, I just started the car in the a.m. and was backing out of the garage. It started sounding and acting funny as explained and the engine light was blinking.
Cons: caused smoking fire
