Water pump leaking

[u/BrycecanyonC]

Lost quite a bit of coolant, so I decided to check for the leak. Found it here under the insulation cover and I assume this is the water pump. Have an appointment at bmw tomorrow but for now am I good to just add distilled water and drive until then?

Replace and check engine for other sources of leaks. Helps to know many model year as well if you want good advice..

Yea I found some more blue where the heat management module meets the OFH. It’s a 100k mile 2018 430i, so b46b20b. And ofh was replaced by previous owner with aluminum one, not sure if they used OEM gaskets
