Not Turbo “Spoiler Error Adjust Speed” on 2014 4S
#16
I had same issue this week.. All started from a weak battery which caused a few other issues which went away witj the new battery.. The spoiler issue remained.. I took my 911 to an independent local shop and they recalibrated the car using their scan tool hooked into the the cars OBDII port. $60 diagnostic charge and all is well.
