Many months ago, someone else had the blinking service light which would NOT shut off. I think he fixed it with a hammer or took the bulb out. There is no documentation about it blinking or what to do if it does. Perhaps the car just wants to get to a dealer???

As for your DTC and no CEL, that is perfectly normal. Some codes require multiple hits to turn the CEL on, such as the slow responding O2 sensor. Don't worry, it will come back and blink at you when you least expect it.

The shifter light "should" come on in W mode or a gear lower than D. Unless there is a tranny error.
