Default Cannot bleed after SMG Relocation

SMG system worked without error before relocation.

1. Applied 12v to each solenoid and click is audible and measured resistance which also looks good (2.8 to 3.0 ohms).

2. Jumped SMG relay pins 2 and 6 and pump motor runs strong

3. I filled the aluminum block full of hydraulic oil before seating solenoids

4. Attempting to bleed actuator or clutch cylinder using INPA, DIS, AutoEnginuity, and Schwaben fails. No mechanical noise can be heard. Actuator bleed fails very quickly.

5. I cannot shift to 2,3,4,5, 6 or R using any of the software mentioned above. Seemingly stuck in 1st gear.

6. I am using a ctek 7002 in power supply mode to maintain voltage.

Any ideas cause I'm out? Thoughts are appreciated.

I suppose it could be Gear Position Sensor since I cannot shift gears using software and receive error 50 "selector angle cannot be regulated". Just odd for the GPS to fail at the time I performed the relocation.

Edit: Should be noted I reconditioned the pump with all new seals and o-rings prior to relocation. After re-assembly I tested the rotation of the gears and there was no gear bind evident. They rotated freely. I made sure to label each solenoid's position and wire color as well.

You also topped up the black accumulator and resevoir with hydraulic fluid? The pump doesn’t like to run dry and won’t prime without/low fluid.

I made sure to press the external reservoir line into the pump housing fully and then slowly filled until it starting backing up and couldn't take anymore. Accumulator was filled prior to re-assembly. It didn't take much to fill the accumulator.

Default Re: Cannot bleed after SMG Relocation

Check the pump pressure value from INPA
If your pump doesn’t hold enough pressure it will not release the first gear and will keep falling as soon as you start bleeding routine.

Default Re: Cannot bleed after SMG Relocation



I was having issue after reconditioning and relocating the SMG pump
Where I got zero pressure with new accumulator and Burkhart e-motor



I replaced the internal seal on Bosch part



ended with enough pressure to bleed the clutch

Default Re: Cannot bleed after SMG Relocation

Thanks for the ideas ahmed_alghoul but I did replace those seals with new ones during this process.

If no one else has any ideas I'm going to disassemble the pump again and make sure everything still looks to be seated correctly and that the aluminum pump plates all appear to be in the correct orientation.

Default Re: Cannot bleed after SMG Relocation

In thinking about this the pump motor and accumulator pressure can't come into play at the beginning of the bleed for the actuator as the SMG relay is unplugged. No relay, no power to the motor ergo no pressure within the accumulator.

With that said why can't my actuator at least begin the bleed process?

im pretty sure you need to reinstall the salmon relay to perform the bleed procedure.

you need power to energize the pump which uses the accumulator to pressurize. also the clutch bleed procedure also needs the salmon relay as well to energize the pump to send fluid to the slave cylinder. so you cant do anything with no relay installed.

My understanding was, and DIS even warns you of this, is that after working on the hydraulic system you are not supposed to plug-in the relay until the actuator bleed tells you to. So I was thinking the bleed would start and then I would essentially get a message saying "ok, go ahead and plug-in the relay" or something of that sort.

i read some instructions that mentioned that but i used INPA to do all my bleed procedures and i couldn't do anything with the relay pulled.

i just made sure my accumulator and pump were full and my reservoir were full and put the relay in and performed my bleed procedures.

your pump would have to be bone dry to have any negative effects anyways. you had residual fluid in the system + you topped off all components so you will be fine.
