I drive a 2011 Porsche Panamera and I have a gremlin in the door locking system: when I lock the door with the remote the car bips twice and all is well and all of a sudden it does not bip anymore and the driver door is not locked. If I open the drive door after the alarm goes off.
This has happened twice.

Anyone ever had this issue?
