SMG Pump Components & Hydraulic / Bleeding procedure.
I would like to check my SMG Hydraulic Fluid level and bleed the system on my 2007 M5. I've been looking around for a DIY on this or any talk about doing this process, but haven't found anything...
First - Seems that the term SMG Pump and SMG Motor are used interchangeably... Also, many people have asked where the heck do we fill and check the SMG Hydraulic Fluid? Seems like a simple question, yet I haven't found a clear answer... I seriously believe some think that it's the Power Steering reservoir, just because the two use the same CHF11S fluid!
I attached what I believe to be a good side view picture of the SMG Hydraulic Pump System. I labeled each component based on my understanding from reading several threads. Please correct me if I mislabeled something so that it will help any newcomers like myself!
1 - SMG Hyd. Fluid Reservoir Tank with Vent on top?
2 - SMG Hyd. Pump Motor?
3 - SMG Hyd. Pump?
4 - SMG Hyd. Pump Block?
5 - SMG Hyd. Pump Solenoid?
Are the Fill and Drain plugs correct?
Second - Where can I find the correct procedure to top off the SMG Hydraulic Fluid Level and Bleed the system to be free from any air? Assuming I need to add Fluid, should I drain all old Fluid out instead of topping off with new? I have DISv57 on my laptop now.
