Ignition coil Denso or OEM Volkswagen

I read up some online and decided to order new ignition coils. Took a few days, but I got four new coils and threw them in. Again, problem solved it seemed. No more EPC light, misfire codes didn't come back and no more rough starts.

I was having hesitation problems a few months ago while accelerating. No CEL, and no codes with VAG-COM. I read here that a lot of other people had had identical problems; the CEL and codes didn't start appearing until well after the symptoms started. Changing the coils solved their problems. So I took the risk and changed all four coils (at about 65,000 miles). That completely solved the problem for me. By the way, the new OEM coils had a completely different part number than the original ones.

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.

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.

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.

had the same problem in the gti...just got a replacement coil pack for 32$ at the VW dealer and was good to go...i hear its a common thing to replace...
