This bulletin applies to 2017-2018 Porsche Boxster vehicles. The instrument cluster may at times display a warning message “Refill Coolant Immediately!...Do Not Drive On.”
Due to an error during production of the locking lug, the electric plug connection on the coolant reservoir cannot be locked correctly.
In the event of a complaint and if the plug connection is loose, the coolant reservoir must be replaced. It is not enough to just re-connect the electric plug connection to the existing coolant reservoir.
An adapted coolant reservoir has been installed as standard since April 10, 2018. The corrected reservoir is available as P/N 982.121.407.C.
