Q: why does my check engine light keep coming on in yellow? on 2010 Porsche Panamera Turbo

it started after I returned from a four day trip where the car was left at the airport. I returned to find the battery dead and had the car jump started. For weeks all was fine, then the auto start/stop function deactivated followed by a check engine light. Porsche first thought it was tied to the thermostat, then later to a computer setting which was changed by the jump - to which they claimed to have reset the computer and the issue should be fixed. I got the car back and within 20 miles of driving the stop/start deactivated and check engine light came back on. I would appreciate any insight or recommendations.
The Dealership did not address and repair the problem , take it back and ask for you many back or make them properly repair the problem. Their assessment of the problem was inaccurate. I think that this is pretty obvious.

Best of luck!
