Can someone tell me what the following error code means on a 2009 Mercedes CLK 350, please?
B1115,B1118,B1128,B1134,B1130 and Airbag module is faulty

Update: Some googling provided me with these explanations. But I am not sure if they are correct or what they actually mean.

B1118 Fault in CAN communication with control unit N93 (Central gateway control unit).
B1128 Control module ICS Instrument cluster with service interval display has detected undervoltage.
B1134 The CAN signal for the 'driver door' door contact switch from component N10/8 (Rear SAM control module) is implausible or missing.
B1130 The instrument cluster no longer transmits over the engine CAN databus. Status 'CAN bus OFF'
