Welcome to RennTech :welcome:

 

First thing you need to look at is the charging system (voltage excursions cause no end to ghost MIL lighting up).  Load test the battery and check the alternator for correct voltage (around 14V).  I would also scan the car for any other information.

There is a TSB out concerning faulty ground wiring. This can cause all kinds of warnings also. But as JFP says, start checking the alternator output. Look for an output of 14.0 volts or higher. Apply load from, lights and seat heating, etc. and make sure voltage does not drop down to much. You don't wanna see anything below 13.2 volt I would say.

Page one of the TSB states:

 

 

Attention: Service Managers/Service Technicians

 

Vehicle Type: Panamera S/4S/Turbo
 
Model Year: MY 2010-2011
 
Concern: Check Engine light illuminated with various fault codes stored in the DME.
 
Information: There is the possibility of faulty splice points in the engine wiring harness which may cause various
fault codes in the DME.
 
Splice points VS1 and VS1_1 provide the ground path for multiple engine sensors to the DME pin B42
"Ground Engine Sensors".
 
If the vehicle has been in the workshop multiple times for a check engine light, check the vehicle's
entire history of DME fault codes to determine if this ground splice may be faulty.
 
Any combination of faults for the sensors listed may indicate this ground splice is broken or faulty.
• Mass air flow implausible (P0068)
• Intake Manifold pressure sensor (P0069, P0106, P0107, P0108, P1183, P1184)
• Engine Coolant Temperature Sensor faults (P0116_P0119, P050C, P3081, P3082)
• Radiator exit Coolant Temperature Sensor faults (P2183_P2186)
• System too Lean or too Rich (Bank 1 & Bank 2) (P0171_P0175)
• Oil pressure sensor faults (P0521_P0524)
• Oil Level sensor faults (P250C, P250D)
• Oil Temperature sensor faults (P0195, P0197, P0198, P0298)
• Boost pressure sensor (P1189, P1190, P1637, P1638, P1639)
• Camshaft position sensor 1 & 2 (P0341_P0349)
• Crankshaft position sensor (P0335, P0336, P0370_P0373)
• Engine Compartment temperature sensor (P1154_P1158)
