It would be helpful if you state the exact model and year. When I see that many electrical faults I think battery - battery connections including grounds. -
Puzzling fuel issue.

Are you sure both pumps are working? -
Fuse Short to ground or open circuit (bad grounds are common for Cayenne) Low battery voltage Then start checking individual control units

Yes, the control is inside the PDK. Likely best it be checked with a PIWIS.

P1990 PDK Software monitoring A (or B) of signal processing unit Possible fault causes: - PDK control unit faulty Fault effects: - CAN alive counter freeze - Engine speed limitation - Transmission limphome indication in instrument cluster control unit C150 DME control module, communication Possible fault causes: - No power supply for DME control module - DME control module incorrectly coded - Short circuit or open circuit in the CAN drive - DME control module faulty (in most cases the cause is not the DME control module but incorrect coding!)
-
Sometimes when there is a voltage spike to the system (like connecting a new battery) the programming can get "mixed up". When this happens the best thing to do is have a tech/shop with a PIWIS re-program the affected control module(s). I think it very rare to replace a DME if most everything but one or two items are not working.

As long as the majority are in the 1-3 range then it is usually considered good.
