Fault code B1788 .....Help?Central Auto Locking???? M-Class

Please help,
I had problems with central locking on my 2001 ML270cdi.
The rear passenger door lock was machine gunning.This has been replaced and the drive off locking is still double locking.Also when locking the door by the remote they all double lock.My garage (not MB) replaced the faulty lock but cannot rectify the double locking.The diagnostic fault code reads B1788 (stored in the base module) but with no description.Are these related?

Thanks in advance
