Condition
When replacing the 12V Li-ion battery, PHEV models no longer need or support an additional crash shield (often 		
called a crash plate or reinforcement).
Technical Background
Previously, all Cayenne replacement 12V Li-ion batteries were supplied by LG Chem. These batteries require an
additional crash shield that the workshop ordered along with the battery. Porsche recently adopted an A123 battery 		
for PHEV Cayenne only. This new battery is reinforced internally and does not need an additional crash shield.
However, the gasoline powertrain models still require the external shield as of the release of this bulletin.
