The service functions must be carried out in the relevant order!
SMG TRANSMISSION SERVICE FUNCTIONS
| When replacing SMG control unit | 1. Teach in clutch valve characteristic values 2. Adapt complete transmission 3. Teach in clutch slipping point 4. Teach in offset of longitudinal-acceleration sensor |
| Before working on the hydraulic system, if the system: - is to be opened - is filled with hydraulic fluid (depressurization of hydraulic system) |
1. Reduce hydraulic pressure |
| After working on the hydraulic system, if the system was opened | 1. Bleed actuator block 2. Bleed clutch slave cylinder and hydraulic lines |
| After removal and reinstallation of parts (no replacement of parts!) - Engine - Transmission - Clutch |
1. Teach in clutch valve characteristic values 2. Adapt complete transmission 3. Teach in clutch slipping point |
| When replacing transmission When replacing hydraulic unit with actuator block When replacing engine |
Note: Perform points 1 and 2 only if the hydraulic system was opened. 1. Bleed actuator block 2. Bleed clutch slave cylinder and hydraulic lines 3. Teach in clutch valve characteristic values 4. Adapt complete transmission 5. Teach in clutch slipping point |
| When replacing clutch | Note: Perform point 1 only if the hydraulic system was opened. 1. Bleed clutch slave cylinder and hydraulic lines 2. Teach in clutch valve characteristic values 3. Teach in clutch slipping point 4. Reset clutch curve (automatically carried out by BMW diagnosis system after successful teaching in of points 3 and 4) |
| When replacing individual clutch parts: - Release lever - Ball pin - Release bearing ... |
1. Teach in clutch valve characteristic values 2. Teach in clutch slipping point 3. Reset clutch curve (automatically carried out by BMW diagnosis system after successful teaching in of points 1 and 2) |
| When replacing clutch slave cylinder with PLCD sensor | 1. Bleed actuator block 2. Bleed clutch slave cylinder and hydraulic lines 3. Teach in clutch valve characteristic values 4. Teach in clutch slipping point 5. Reset clutch curve (automatically carried out by BMW diagnosis system after successful teaching in of points 3 and 4) |
| When replacing longitudinal-acceleration sensor | 1. Teach in offset of longitudinal-acceleration sensor |
