I took my 2017 S P100D to the service center early yesterday for the AP2.0 to AP3.0 upgrade. The service center said that it would take around 4 hours to complete. It has now been almost two full days. The service center informed me that they are having software issues with the car and that engineering has been working on it. Has anyone else experienced this issue? I searched the forum and did not find any similar threads. Thanks!
