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.

For what it's worth, I used to run the cheapest 235/40ZR18 tires I could find on my Jetta(Sunny brand if I recall), after a few years, I never had any complaints. Paid about $105 each and they seemed worth the money to me and not much different than the name brands($200+ each), at least as far as durability/safety was concerned
Update: There was a direct short in the alternator and when it shorted internally it also took out the 200 amp protection fuse ($115) too for the battery. I got a new Bosch unit and I was happy to find out I did not have to bring it to the nearest dealership and that a local German repair shop were able to do it.
Buy 5L Vaico brand G13. Flush the system several times with distilled water. Then drain and purge with compressed air. Disconnect the heater core lines. Then pour in all 5L of pure antifreeze, and top off with distilled water.
when i had my 03 wolfsburg i ran 225/45/17 dunlop signature HP's, amazing tire for the money
Same, with a 2015 on stage 2 tune it can be pretty quick and on road trips with the cruise set to 70 it can pull some pretty fantastic fuel economy.
I'd recommend getting a kit like this (...) from idp because it has a Graf pump, which has a brass impeller - some kits use plastic.
I had bought this INA oil pan for the old car because it could corner well enough that I had oil starvation problems around some longer turns. I figured that it's an even worse problem to have with a K20 because it uses oil pressure to control valve and camshaft timing, so I had to find a solution to that.
my valeo radiator didn't come with anything.. im just hoping it doesn't leak from that zone.
I just purchased a set of Bosch Icon wiper blades(19OE & 24OE) for my wife's '11 Jetta and I can't figure out how the heck to put them on. I took off the plastic piece that it comes with and tried to slide them into place between the walls but it seems that they have these little plastic edges that stick out and don't allow me to get the full mount inside.
