Re: 2009 FEH wrench light P0A7C
Hello,
I'm experiencing the same issue with a 2009 FEH. P0A7C triggers at 70+MPH REV 3k+. Did anyone figured out a solution? I will be checking the transmission pump, and may replace along the dc to dc converter.
Any tests or PIDs that i should be running/monitoring in forscan to help troubleshoot?
Looking a bit further, I also found Code: B12B8 - Driver Blend Door Actuator, Slow or Door Obstructed which also brings in the wrench light and few people experience the same symptoms, light coming in after 1 hour, 70+ MPG, RPM 3k+. I will change the blend door actuator and will report here.
Thanks im advance
