looking at a 2010 q7 tdi next week, is there a link to common problems?
 

I want to know what to look for, I've owned multiple Audis for the past 20+ years and need to get something newer than the d2 she's driving with nearly 400k miles on the clock.

Thanks,

Keyless door handles fail. They tend to unlock once pulled slightly but the lock button goes short to ground and this in turn causes battery drain issues. Sunroof leak were mostly fixed by 2010 but check for signs of previous moisture round the spare wheel well.
Check or smooth up and down changes - that should be the 8 speed trans which are generally very good.
Has it had the emissions fix yet?

Was the emissions fix on both the gas and diesel?

Just the diesels
