Help needed fault code 5e20 wont clear

Hi Guys im currently working on a customers car BMW 1 series 120 d turbo 2006 original fault was dsc traction control yellow lights all up on dash fault codes
5e40 Steering Angle sensor signal not Plausible, offset
5e24 Pressure sensor 1 not plausible
5e20 Pressure sensor 1 electrical faulty

I sent the abs pump to a company who repairs and tests these units and they told me the pump was faulty and repaired after i received my repaired pump fitted it and bled the brakes trying to clear fault code which wont clear is
5e20 Pressure sensor 1 electrical faulty no matter what i do this fault wont clear so i sent back the pump which they again tested and said it was fine no faults or codes stored i should be receiving it back tmrw but not sure what to do if this code wont clear im using a snap on ethos anyone have any ideas would be of great help surely its not a wiring can fault otherwise the pump wouldn't have come up faulty? thanks again

There's a particular method for properly bleeding the ABS unit after installation. It requires the use of a scan tool that can access the DSC module and cycle the valves open and closed to extract any air bubbles that would otherwise be trapped inside. I don't know if the ethos has this capability or not.
Also, you might want to track down a service manual for your car to be sure you're following this procedure to the "T."

Hi thanks for your suggestion i was thinking about using something like that to bleed so i prepared myself and bought this kit off ebay what a load of crp so anyway i put the pump back in bled the brakes again and light still there so i started it and with my self bleeder still connected to my tyre giving me the pressure i pumped the pedal while i went round again then the light did reset this time so not sure if it was a bleeding issue or whether this company never cleared the codes from this pump properly the first time? but its all sorted now but i would like to get this new software working but you need to be a computer programmer thats what you get for £26 off ebay cant expect miracles ey
