BMW 550i navigation control module unresponsive after water spill on BMW 550i

Some BMW 550i owners report experiencing issues with the navigation control module becoming unresponsive after a water spill. These problems may manifest as a frozen screen, lagging, or sudden shutdowns, necessitating prompt attention to prevent further damage. Owners have found that performing a soft reset or a more thorough hard reset can sometimes reboot the iDrive system and resolve these issues. In some cases, a software update from BMW is required, particularly if the problem is linked to the EPS control module. Additionally, if the module has sustained damage from the spill, it may need inspection for corrosion, and depending on the extent of the damage, replacement parts like the steering motor may be necessary to restore functionality.
