Just came off a 4hr round trip... no problems what so ever...parked the 06 X3 218k on the clock m54b30.
Parked her couple of days for "rest".
Returned to take her to the car wash...instantly notice low coolant light illuminated.
Went to add and coolant went straight to the floor. I'll investigate later for where the expansion tank popped (i guess) yeah! It popped...split right down the side ...delivery should most likely be after the Christmas holiday.
