| Convenience system central control unit -J393- | The convenience system central control unit -J393- incorporates the functionality of -J518-. The diagnostic address is 46, as before. |
| Entry and start authorisation control unit -J518- | The functionality is integrated in the convenience system central control unit -J393-. The diagnostic functions for the entry and start authorisation control unit -J518- are still accessible at diagnostic address 05, even though the control unit is no longer available as a separate unit. |
| Onboard supply control unit -J519- | Diagnostic address word 09 |
| Data bus diagnostic interface -J533- | Diagnostic address word 16 |
| Control unit in dash panel insert -J285- | Diagnostic address word 17 |
| Central locking and anti-theft alarm system aerial -R47- | |
| Driver door control unit -J386- | The control unit and the window regulator motor are two separate components. Two door control units are distinguished (driver door control unit and the front passenger door control unit). If the convenience system central control unit -J393- fails to function, the driver door control unit -J386- takes over the master function for the central locking functionality. |
| Driver side central locking lock unit -F220- | The lock unit integrates the following components: Front left central locking actuator -F131-, driver door contact switch -F2-, driver side contact switch in lock cylinder -F241-, driver door central locking motor -V56-, driver door central locking deadlock function (safelock) motor -V161- (not on USA vehicles), driver door central locking actuator for deadlock function (safelock) -F243- (not on USA vehicles). |
| Driver side interior locking switch -E150- | |
| Front passenger door control unit -J387- | The control unit and the window regulator motor are two separate components. Two door control units are distinguished (driver door control unit and the front passenger door control unit). |
| Front passenger side central locking lock unit -F221- | The lock unit integrates the following components: Front right central locking actuator -F133-, front passenger door contact switch -F3-, front passenger door central locking motor -V57-, front passenger door central locking deadlock function (safelock) motor -V162- (not on USA vehicles), front passenger door central locking actuator for deadlock function (safelock) -F244- (not on USA vehicles). |
| Front passenger side interior locking switch -E198- | Only on vehicles for USA |
