Update: Dealer service Mgr & Shop Foreman stated that the engine adaptations needed to be reset. This wasn't done after they replaced the pressure converter, and stated it normally isn't necessary. They claim that since the adaptations were not reset, that the existing engine parameters were not off, and there wasn't sufficient time for them to reset before the Drive Train alert. They reset the adaptations, drove some 70 miles, and were not able to trigger the alert. Vehicle was delivered Thur, we drove yesterday around town w/o alert. When dealer delivered vehicle, I did notice somewhat unusual ticking sound to the engine (lifter noise?), and my wife noticed the same yesterday morning as we headed out. Sounded similar to what we heard when we had timing chain issue 3 yrs ago. We notified the dealer of the noise, and their response was "sounds coming from engine are totally normal and engine is under warranty if there are any issues."
