Ignition coil Denso or BERU

I replaced the old ignition coil with a Denso one. The car is running great after the replacement.

Make sure to spend a little extra and get the Denso brand coil. The cheap one don't last very long.

Short answer - it was the ignition coil. In the end - it serves as a reminder that just because a code (or lack of) seems to point to a specific component, you MUST diagnose. ECM costs $300 - $1000 including coding - a Denso ignition coil was just over $100.

I personally dislike HUCO brand which it had, I replaced mine with a BERU coil, still going strong since '97.

My coil is a Beru and pretty much brand new.

many thanks to this diy i just successfully replaced my unbranded made in italy POS coil with a brand new one from beru. gosh, as soon as i put that in and started the car it didnt start so rough. what a small but significant change, kudos and thanks!

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 am currently using the cheaper version because I just never put in the 'thought-to-be-bad' pack back in [btw, it was an injector so both packs were perfectly fine]. With that in mind, I cannot say there was any quality increase because it was never my CP to begin with so it was still misfiring even with the $350 BERU. But, what they did both do is act exactly the same when I put them both in. I have not had any problems thus far with the cheaper one, and it feels about the exact same quality as the beru brand.

Car was misfiring, so I replaced the ignition coil unit (old one was showing cracks). I replaced it with a Beru (OEM) unit. Car went from a sputtering mess to running like a top.

Bought new coil. Lucky to get good German Beru unit for little over $90...last of luck. Put in new coil, still no spark.
