I don't mean to be alarmist, but severe pinging is often mentioned as a precurser to piston damage caused by faulty mass air flow sensors. They never set a fault code for the MAF, but the sensor causes a lean condition which leads to the tops of a piston or two (always 1 or 4 or both) turning to a chunky powder. Every time I replace one of these engines, severe ping is noted by the customer prior to the breakdown. I had one last week that was pinging and cutting the boost way back on a road test. I replaced the MAF and the ping went away and the boost came back. That guy saved his engine by bringing it in before it was too late.
