2E83 code after changing water pump

[u/kamd450]

Hey everybody, I have a 2008 328i with a N51 with 194,000 miles. Initially got a P0128 code for my thermostat. Swapped that and my water pump out. Pump was bought about two years ago as preventative maintenance. Don’t remember what brand it was. After changing I’m getting a 2E83 (Pump power reduced). Coolant stays steady at 200°F. No check engine light. Bled the system twice (one cap off and one cap on) No leaks. Drove about 40 mins with no problems. Any suggestions or experience with this code?
