Panamera Hybrid: Reduce Speed - Check Engine Warning
Does anyone have insight on what could cause a dashboard warning “Reduce Speed” “Check Engine” when accelerating rapidly? This has been a chronic problem with my 2012 Panamera S Hybrid since I bought it two years ago with 47,000 miles. This is the 3.0 L supercharged V6.
The warning does not occur every time, but frequently enough. The car’s performance doesn’t seem to be impaired and when I pull over and switch the ignition off and back on, the messages clear. The dealer has worked on it, but has not been able to identify the cause.
It has also been to the dealer twice to clean carbon deposits from the secondary air injectors, which caused a continuous “Check Engine” light. The light has not returned and doesn’t seem to be related to the acceleration issue, but I am including this information in case someone sees a connection.
I would appreciate any thoughts!
