Cracked coolant pipe between the engine block and the left cylinder head on the Panamera 4SCooling

Engine / equipment: Panamera 4S (971) 2.9 V6 biturbo
Period mentioned: 2017–2018
Symptoms: Coolant loss: a stain under the engine, a smell of hot coolant and, if not noticed in time, the temperature and coolant level warning lights on at the same time.
Possible cause described: The coolant pipe joining the engine block to the left cylinder head (cylinders 4 to 6) can crack over time because of vibrations in the cooling system. Porsche replaces it with an improved pipe in service campaign WJ26 (technical information 45/18, October 2018).
Check for the garage: With the temperature warning light on, stop in a safe place and do not drive on; do not open the reservoir when hot. At the garage, have them check the pipe between the block and the left cylinder head and whether the car has campaign WJ26 outstanding.
