Hello together, with my beloved Subaru WRX STI spontaneously went out on Thursday on the AB of the engine and could not be started. I was not at the moment fooled, did not kick him before it and I also drove for about 15 minutes. likewise no signs of jerking, no bang, no temperature or anything else. just spontaneously went out. Now Subaru towed him away and as a next diagnosis said that the timing belt has torn and the engine This was already an exchange engine which had, however, “first” 100,000 km on the clock. Basically I trust my dealer, but can it be? Shouldn’t there be at least a bang or any signs? thank you and LG
