Walk-in at dealer service, in and out 1 hour, they said diagnostic shows knock sensor was at fault and cleaned and replaced with original knock sensor. 200 miles later, same issue - no throttle response at 3000 rpm, followed by solid yellow cel. Dealer says ok to drive on, come in next apt. 5 days later. Car in and out same day, they cleaned both knock sensors and replaced with originals again. 300 miles later same problem - no throttle response, cel, etc. This time dealer replaced both kock sensors with new ones. The same issue repeats another 2 times. Dealer has been in touch with vw tech line since episode 3 because they tell me it is a "warranty issue".
