Hi all. New to the forum. I'm about to make payment on a 2019 SDV8 but somehow wanted to be sure so I plugged in a Launch X431pro diagnostic scanner to read the codes and found the car to have multiple errors on engine and transmission. Seller have shown recent receipts of new dpf and engine module and a used rear axle, so I am not sure if any of these are related to the error codes.

ECM (Engine Control Module)

1. P250D-37 Engine Oil Level Sensor - Circuit High. - Signal Frequency Too High
2. P250B-87 Engine Oil Level Sensor - Circuit Range/performance - Missing Message
3. P064F-00 Unauthorized Software/ Calibration Detected - No Sub
Type Information

TCCM (Transfer Case Control Module)

1. P0810-62 Clutch Position Control Error [P081 0] - Signal Compare Failure

Please help. Thanks
