So I've run the reader in both modes, and this is what I've got
  • Code: P2002 - Particle Filter Efficiency Below Threshold - I've cleared the error, and I'll refill with new diesel and see if it comes back
  • Code: B2477 - Module Configuration Failure / Module: All Wheel Drive Module - I have done some googling and have noticed the car either misfiring at about 2500 RPM in 2nd gear around when the turbo is spooling.
  • Code: B1317 - Battery Voltage Too High - The previous owner had mentioned it had a new alternator recently, and there are receipts for a new instrument cluster. I'll have to do some more digging into this with a multimeter.
  • Code: C1278 - Steering Wheel Angle 1 and 2 Signal Fault - I'll try to reset everything on ABS and see if it comes back.
  • Code: B1318 - The battery voltage level is too low. - Module: Antilock braking system - Like above, I'll try a reset.
  • Code: U1900 - CAN communication bus fault - All the backlinks on the forum appear to be broken, so I'll do some more hunting.
  • Code: B2976 - Control line to EAH open circuit or short to ground -
    Control line to EAH open circuit or short to ground
Not looking like anything major, the misfiring is probably my most concerning.

Please chip in if you have any pointers.

If all the error messages are new and not historic , they are not date stamped, then I would look for a common cause especially with that build year .
Clear the error codes and slap the dash and see if they re appear or remove the instrument cluster and wiggle the connector. If it triggers the errors it could be dry solder joints in the cluster.
Fairly quick check could save a lot of work/cost
