About to drop the hammer on a Q5..coming from a A4 Avant

[plum]

Well I have had a problematic 2009 A4 Avant that is almost out of warranty and found a nice 2013 Q5 S-Line with 56k.

The Q has warranty and is a certified to 160k so there are no issues for a few years on warranty...is there anything I should be cautious about? BTW it is a 2.0

carbon build-up on the valves have been an issue, altho i'm not sure how major. with these direct injection cars, fuel does not wash over the valves anymore. for 2014, audi added an additional injector on the intake side to address this issue, i believe. but this additional injector wasn't there in 2013 and earlier models.

Good to know...I have been lucky with my A4 (although they did replace the pistons et all for oil consumption)
