I have a 2012 VW jetta gli 2.0 turbo dohc 6 speed transmission. We've replaced ignition coils, spark plugs, fuel filter, had injectors cleaned, still runs rough. Engine light blinks a few seconds and then stays on. I haven't driven it in weeks because I dont want to mess it up! We buy only OEM parts. I've talked to people and they think it might be electrical, but it's a guess.
