Ignition coil Bosch or Denso

I had this exact issue and just fixed it with a new ignition coil. I bought a bosch replacement and I haven\u2019t had the issue since.

Make sure when you replace these you use too quality plugs from a reliable parts store, too many stories of bad fakes or lower quality products from online sources. Coils are also likely a good idea at this point, again go with Bosch, again from a reliable source.

I bought a new Denso coil to put on cylinder 3 just to eliminate it as a possibility.

I was chasing down a P0352 CEL. I moved the #2 COIL to the #1 cylinder and the CEL followed the coil (P0351). I ordered the first Denso Coil from Amazon ($53), knowing there could be a possibility of a fake/counterfeit. CEL disappeared.

I'd recommend Only the denso coils. I got a denso and that's lasted about a year so far.

Denso coils are good for another 150,000 miles

As per ignition coils, the only ones you should buy for N43/53 engines are Bosch. All the others (Delphi, Febi, HP etc.) are the same Chinese coil sold under different names, same issues as the counterfeit parts.

Few months ago I got all 6 OBD1 Bosch coil packs and it changed nothing for me other than a slightly smoother top end, I still have a slight misfire at idle.

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 ????

I replaced all 4 in my tuned stage 2 q3 2013 to red bosch coils. 1 of the red ones died last year.
