Looking for x6 n54 what issues to look for?

[Brule]

Hi All,

I am looking at getting an early x6 2008 model.

Just wandering what are well known issues with awd or trans at high km?
What to look or listen for?

I have had an e92 n54 for 5 years and k ow the engi e pretty well but do not know anything about repairs or costs of awd issues.

Looking at cars with 100-165km currently and need to know if its worth getting the lower km car or not.

From Australia if it makes a difference.

Cheers
