P1447 Code - Reset SE light

Newbie here.. to wake up this thread again.

I recently purchased a 2011 328i from a one owner. 74K miles. Put about 1200 miles on it and the SE light comes on. Went to local Advance Auto.. P1447. Diagnostic Module Tank Leakage (DM-TL) Pump Too High During Switching.

K. I have read this thread several times. I just yesterday installed a NEW Bosch pump. $69. I have read a couple of post about how to reset the light. I have disconnected the battery cables... Touched the cables together. Put them back. The SE light is still ON.

What did I do wrong? Any thoughts?? Thank you!
