Drivetrain malfunction

icloudfiles · 08-22-2021, 10:00 AM

Got the warning on my drive back after a track day. Pulled over and let it sit for 5 mins and started up again. No warning and it drives fine. Checked for codes via carscanner app and there were none. What’s the best way to chase this?

What was your fuel level while on track?

i've heard under a certain amount of fuel and being driven hard pulls this sort of code all the time

Unfortunately it is a common issue on track if the tank goes below 1/3 full. When you say drive back after a track day, was this on the way home or back to the pits after a run? It's peculiar for that to happen under normal driving conditions on the street.
