Around 2 months ago, one of the starting coils failed. I checked here and some said that the stock "Delphi" coils are known for failing. So i changed all of them for "Bosch" coils.
get the Bosch brand their the same as OEM trust me I know don’t get any other brand even though their going to be cheaper get the Bosch. Besides honestly most of the ignition coils is Bosch companies just throw their name on it to charge more
Get a Bosch and skip the brand logo. Same part and available…aaand cheaper. Same issue for me c63s.
Bosch working great for a few years now, cheap as dirt on rockauto
I bought the Bosch 4 yr and 10k miles ago and haven't had issues.
I've switched from standard to the Bosch ones last summer and it significantly improved the acceleration on my 124 Abarth. Prior to the switch I'd see lots of misfires and "bumps" in the power delivery curve. The Bosch set was not a hard sale with being under 280€/260$ here in CZ. Highly recommended for anyone with power mods.
I bought four of these from the Audi dealership and slapped them into my MK5 GTI when I replaced the spark plugs. They work but they aren’t any performance upgrade. I got ‘em because the car is also red ????
Coils: buy Bosch or Delphi coils. DO NOT BUY THEM OFF OF AMAZON. You would be better off leaving them then replacing them with an aftermarket brand.
I replaced my coil around the same time, and no start failures for me either.
I gave the Jetta back to my son last week after replacing the coil. No issues yet - but mine was happening less frequently.
