Problem:
I programmed a new key on a BMW F10 CAS4+ using Xhorse VVDI Key Tool Plus via OBD. After programming, the remote functions and Comfort Access work perfectly on the new key. However, the car won’t start. Before programming, the original key started the car normally with Comfort Access. Now, even the original key no longer starts the car wirelessly.
Solution:
Sync CAS to DME and will start again.
Go to Special function- synchronisation CAS – DME.
