971 - No power at dash, no start
Hello Everyone. I'm at my wits ends and am now reaching out for help or insight into an issue I'm having.
The car is a 2018 Panamera 4S Sport Turismo.
The issue is no power at the dash and no start. Happened suddenly. Drove home on Thursday just fine. Parked the car. Came out Friday. Hopped in the car to go to work, flipped the switch..... and nothing.
To date here is what I have done:
Tried jump box. No go.
Tried both keys.
Put fresh batteries in each key, and tried again.
Tested battery voltage. Just fine.
Changed the battery in case there was an internal short.
Checked the various connections at the battery
Checked the fuses on the positive side of battery
Checked the battery isolation switch on the positive lead
Checked the ground from the battery
Checked the ground at the front shock tower
Toned all the high amp fuses in the box to the left of the battery
Toned all the fuses at the front luggage compartment
Swapped and bench tested the two relays at that same fuse block
Toned all the fuses under the passenger seat
Toned all the fuses under the driver seat
Toned all the fuses in the A-pillar right hand side
Toned all the fuses in the engine bay
Swapped and bench tested the three relays in the engine bay
Swapped the ignition switch for new
Pulled the computer above the pedals and checked those connections
Pulled all the fuses in luggage compartment and visually verified
Pulled all the fuses in the engine bay block and visually verified
Pulled the engine bay fuse block out and checked for corrosion or water intrusion (looks good)
The car does have power. Soft close doors work. Seats move. Horn honks.
I am out of ideas of what to check, and I'm open to suggestion.
