X3 Engine and Transfer Case codes

I purchased the Bavarian Technic OBD computer software and interface. I am very pleased with what all I can read and perform. However, I recently performed a check of all modules, mostly because of a new sound that may be transfer case oriented. I got the following codes and could use some assistance with some detail on the codes:

Engine codes:

2EF8 and 2E69...note was "knock sensor, signal 2"

Transfer case:

54C6...note was "oil abrasion".

(I change the oil and filter every 10,000 miles and use Mobil One..so this note does not make much sense)

Any assistance is appreciated! Richard

Code 54C6 is the transfer case fluid wear value exceeded - gauged somehow by resistance monitored when clutch plates operate.

So nothing to do with Mobil1 (0W40?) in the engine.

Don't know anything about the knock sensor codes. Maybe if 91 octane fuel is used always a sticky sensor is not critical?
