So, before I fork out $400 for a water pump I want to be positive it's broken.

I got codes 2E81 and 2E84.

My radiator fan comes on sometimes (1-2 times a week this happens) and will stay on full blast until I park the car - Ktemp goes to 75C while fan is on.
This is why they checked the codes.

Coolant temperature has never gone over 100C in the last three weeks I've been watching it.

Dealer visit was two days ago.

Any advice?

Thanks.
Those are codes for the WP/Tstat on its last legs, don't wait for a full failure... Get it changed ASAP. Find a local indy who will give you a good price or pick up the parts yourself and see if your indy will install them. But get it done ASAP.

You will need a new waterpump, thermostat, new screws/bolts, new bmw coolant. Labor rate of 3 hours.
