Original incident: 08-27-2014
Second incident: 03-27-2019
Third incident: 05-23-2024

In all three of these incidents, I first read the P12 PCM, Compared to previous READS of the same PCM, then Reflashed OS and calibration and resolved the probem.

I have dealer access to Techline Connect. Should I force Techline Connect to perform FULL WRITE and see if it is back again in 5 years? This has me very curious. This car is driven every day by this young man back and forth to work and I see it go by the shop multiple times a week. It is just like a clock, five years go by and here it is again, same problem, same solution.
