2010 Q7 4.2l SLine
 

I am in the process of upgrading from a 2010 A3 2.0T to a 2010 Q7 4.2l SLine. The Q7 has about 100K miles and currently an unknown maintenance history. What should I check or replace from a preventative maintenance standpoint. This will be our primary vehicle and used quite a bit for road trips so I want to make sure the things that could go wrong if left to their own devices are changed out before they fail. Thanks in advance
