20A201- Charge air cooling system: Coolant pump protective function - dryrunning

[NCM2C]

hi all, as the title says i've been battling this code since getting my car back. First check, low coolant all around - especially expansion tank. Refilled & code went away. scanned car today 1 week later to see if there were any codes after doing some datalogs for bend, code has returned. Just checked both reservoir tanks & they have plenty of coolant. Is this a possible waterpump failure?

maybe when it ran low, air entered the system. try bleeding it
