Concerns:
Industrial (250V) NEMA Supply Cable and charging electronics (Porsche
Mobile Charger)
Cause:
It has been determined that the Industrial (250V) NEMA Supply Cable for the Porsche
Mobile Charger
has been enclosed in affected vehicles for which the plug of the connection cable for the in-house infrastructure must be optimized for operation with certain types of sockets.
Higher resistance in the supply cable can increase the risk of overheating and thermal damage to the socket
and adjacent areas. If this goes unnoticed, the local thermal damage could spread and lead to a fire.
Action:
•
Vehicles with Stop Delivery (scope 1): Remove the affected Industrial (250V) NEMA supply cable from
the car before delivering the vehicle to the customer.
•
Vehicles that have already been delivered and assigned to the recall - Porsche
Mobile Charger
Basic and Basic Plus (scope 3-12): Replace the affected supply cable of the Mobile Charger with an
optimized supply cable with an integrated temperature sensor. In addition, the software on the Porsche![]()
Mobile Charger must be updated with the PIWIS Tester at software 43.500.060 (or higher). See ⇒
Technical Information 'Re-programming Porsche
Mobile Charger (Powerboard) - Basic and Basic Plus'
•
Vehicles that have already been delivered and assigned to the recall - Porsche
Mobile Charger
