2013 error P2600. Aux coolant pump

[Ross Hancher]

I got a 2013 b200 w246.
I read fault code P2600 which apparently is auxiliary coolant pump error.
Searching for days it seems the fault code s usually down to the relay, but what relay is it!?!?

Failing that, where is the pump I can't find it anywhere.

Workshop manual would be handy or a full parts list but I just can't find anything.

Please help, why it's s it so hard to find this info?

I dont have a B200.
The auxillary pump runs when the engine is switched off after a journey.
Normally it is at the windscreen end of the engine. If your aux pump is working, then see if you can hear any buzzing in that area.

Can you be more specific.
Fault says open circuit so maybe it's a wire but I can't find the xxxxxc thing

Sorry, I don have a B200.
Any chance of a picture of the engine.
