possible to repair heater valve/pump?

[8 POTS]

Yes, there is the electric aux water pump installed under the heater valves.
I would replace it with a new one. On the other hand I know of some people which removed the aux water pump completely.
This info might help

Thanks 4 help, it is defnitley the small pump below the valves that is leaking, I will have it replaced, but unfortunatly in South Africa you can only get such a part from BMW which costs R1900, which is equal to +/- 160 Big Macs at R12 each.
