As far as I can see, there are no cooling related issues with the car. Everything seems normal to me. No warnings or lights.
However, when scanning with Inpa I get 255 occurrences of this code. 2E85

What's the best way forward to see if I have an actual issue with the pump or with something else.
The code is a communication error with the pump, I think.

Here's the full details....

Late response....
I am driving with it for more than 4 months abd it seems to be fine. Did you find what is it?

General consensus is that it’s a warning sign the electronics in the pump are failing…

Is this the original pump? There was an updated part circa 2015 which resolved a lot of these issues…
