help and suggestions needed. SMG issue journey

[chalaka]

It is definitely fixable. I do not re-oil, the pump, i try to keep it as dry as possible when assembling, once assembled and secure to pump body, before putting back the tiny filter, i drop some chf11s into the tiny hole, then rotate the pump manually from the shaft on where the electric motor the goes, this would give it some fluid so its not dry.

hope this helps..

your experience sharing definitely helps tons.

I'll try to redo my work and follow all the steps suggested ~

Did you ever resolve your issues?

Hope you don't mind if I hijack the thread, but I'm struggling with my SMG system. I replaced the SMG pump assembly last year. This winter I had to replace the clutch and the starter. When I put the system back together, the pump keeps running intermittently. With the key in the ignition, the pump runs for about 4 seconds, builds pressure, then turns off, the pressure leaks down over 10 seconds, and the pump comes on again. I monitored pressure on INPA and the pump is running wonderfully and building pressure, the system just can't seem to maintain the pressure.

I have removed the intake and checked above pump assembly as well as under the car around the transmission and see no evidence of a leak.

Could air be entering the system? The relay and pump seem to be working perfectly. When I removed the transmission, I disconnected the hydraulic lines from the pump housing. I did remove the Clutch slave cylinder to put a new boot on it. Other than the SMG system was not touched.

Where could air be entering the system? Any other thoughts? Any ideas would be welcome, I am very very frustrated.

Did you replace the SMG pump with a brand new BMW unit?
