I have no power

I need to know where is the power off switch

When airbags deploy couple of fuses are blown. Have you checked the fuses?

Customer reply replied 1 year ago
I check all the fuses and all are good. I read online about a power device to cut the power when the airbag deployed. Something under the driver seat next to the battery. I can't move the seat to have access to the battery.
Porsche Mechanic: Gunvir Singh,

If vehicle is equipped with pyrotechnic battery disconnect, which can sever battery connections in a crash. In this case the seat will have to be removed to gainaccess to the battery terminals.

The manufature did not provide any procedure to get to the battery in this case. I found a similar forum that shows the seat removal on a similar vehicle. I have added the link to it. https://rennlist.com/forums/cayenne-diy/850528-cayenne-958-battery-compartment-access.html

Do you have any other questions?

Not having power I can't move the seat to have access to the bolts. The pyrotechnic battery disconnect need to be replaced with a new one or just be repaired ?
Porsche Mechanic: Gunvir Singh,

It will need to be replaced.

I found under the driver seat an switch that is can be moved but still has no power. The pyrotechnic battery switch has the same pugs like the airbag has ? I can see an airbag plug in the top of the battery.
Porsche Mechanic: Gunvir Singh,
 replied 1 year ago

Its not a switch, it is the actual battery cables.
