Earlier this week I had a problem with my 2011 2.2 D4D, first my keyless entry stopped working but the fob continued to unlock the car, then a few days later, while the engine was running, a message on the dash said no key detected and when I switched off the engine the car woud not switch back on.
The next day I came back with the spare smart key and although the keyless entry didn't work, I was able to star the car and drive it home.
This morning the keyless entry worked again with both smart keys.
I ran some diagnostics with techstream ad got the following DTCs in entry and start:
B2784 Antenna Coil Open/Short X Icon C N
B278A Immobiliser Power Charge Malfunction(VC5
GND Short)X Icon C N
Can anyone shed any light on where to look next?
