718 False low coolant warning

Had a "Refill coolant immediately" red warning message pop up the other day. Pulled over, checked the underside, nothing. Visually checked the coolant level per the manual, level was normal. Restarted the car, and the message was gone, water temp was normal as well. Drove the car several times since, then had it recur yesterday. Same as before. Have an appointment with the dealer for troubleshooting and repair. Have come across a Service Bulletin for this problem occurring on 718s built from late 2017 to early 2018 that deals with a faulty part in the expansion tank. Does anyone have any info on this, or have any suggestions on what to expect from the dealer (or cautions)? Thanks in advance.
