Ignition coil HITACHI or BERU

I recently bought a BERU.

I also ordered four (4) new ignition coils from Hitachi, installed them 60 miles ago and it's been smooth since the installation. My car is quieter, more responsive, and idles better. No, check engine lights at all.

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.

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 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.

Has anyone ever experienced an odd electrical type humming sound eminating from the front of the dash after putting in a new ignition coil??? I put in a Beru Coil and I could swear I now hear a faint hum that wasn't there prior to installing the new one. It kind of sounds like the radio with the sound way low when it picks up engine frequencies (but I know it's not that). It definitely sounds electrical and not mechanical and I've noticed the hum increases in frequency when I increase the rpm's. Do coils even make any noise??? Thanks.

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