I had Module Masters overhaul my ABS module in 2017.
Since then, a few stray lights, but in the norm for a BMW.

I am now getting a continuous hard fault. DSC Return pump fail.
Very little info about that pump. Thinking I needed to take Big Red
into the shop. I did what I could on my limited knowledge.
Right before making an Appointment, I called Module Masters.
The technician that is the guru on this specific module called me back.

He said, that this fault.... Return Pump fail, is most likely a module problem.
When My Module was sent in, they didn’t address this section of 5he module.
They do now..

No charge for the upcoming repair!

Yah Hooo
