I drove my car like usual, got home, parked it, went to it the next day and it just wouldn't start and had no spark and fuel injector wasn't activating when I turned the ignition. So ignition coil isn't cracked or anything? A few people were having similar symptoms with that issue. And the E30 relay was $40 from my VW dealer, was going to buy used but thought I better not with the relay haha. Worth replacing since it's a pretty cheap option.
