Error Codes 928 & 930: What Do They Mean?

Hello, I'm having another problem. When I activate the automatic locking, the car locks as it should (at 15 km/h), but the rear door on the driver's side remains unlocked. The error codes in the diagnostic memory are: 928 "Coding Unit for CL Driverside" and 930 "Unknown Troublecode." However, the button goes down when using the remote key fob and the locking button on the driver's door. Sometimes, the diagnostic tool also shows "Status LOCKED" or "SAFE," but the button is still up, and I can open the door.
Can someone perhaps help me with that?
Best regards,

A relatively recent version of VAG-COM would give you the following text:

00928: Door lock module for central locking, driver's side (F220)
00930: Rear left central locking control unit (F222).

'Unknown Trouble Code' sounds like it's coming from another software that hasn't been updated since 1999...

Okay, I think I'll check the microswitches on both doors.
What is the cheapest possible price for a VAG-COM device? And should I order it from the USA?
Best regards,

Take a look at our online shop.
