Owner reviews for ignition coil

The stock ignition coil on our Mk3 Jetta -- which we've had since it was new in 1996 -- just went out about two years ago. Typical crack causing the engine to die when going through puddles. I considered replacing it was an inexpensive Meyle coil. Decided against it, because while Meyle is a German company, their ignition coil is made in China, and I'd heard some bad things. Figuring the OEM VW coil really is over-priced, I finally decided on a Beru coil. It is made in Germany, and so far no problems.

I've had similar spark plugs fouling up issue with the G60 turbo swap in my caddy. After checking all the stuff you mentioned, I upgraded to an MSD Blaster 2 coil and NGK plugs with a wider gap (0.030). So far so good, running on all four cylinders now.

Make sure the new coil is a good Bosch, Beru, or OE unit, not parts-store brand junk. I've seen plenty of bad coils out of the box.

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

Did this conversion on my 2001 Audi A4 with a standalone. I ran it with stock (3ms) dwell and up to 5ms dwell and didnt notice any difference. I was running Hitatchi coils before and would notice slight bumps in idle. Now all I hear is smooth butter at idle.

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!

So far I've replaced all ignition coils (1 died while I was test driving the car, the other 2 years after in the winter, of course). I decided to replace them all with non-faulty Audi parts instead of doing it every year.

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.

Mine is working exactly as it should !!! My cam follower is wearing thin, my DV is busted, my PCV leaks just fine, and i'm starting to think my coils are also going bezerk (but thats fine cause it about that mileage)...

Issam's right about the poor reliability of COPs. We regularly have vehicles in the shop whose spark plugs outlast the coils that fire them by tens of thousands of miles. One 5.4L ford V8 got six new coils before a single plug failed at 90k.
