Purchasing second hand

Well I've been looking at Audi A3
hatchbacks , because these cars have
always appealed to me. Im hunting for one
right now and came across one been sold
by the agents. 2010 Audi A3 2.0tfsi . It's
got a dsg automatic gearboc and is
phenomenal condition in terms of car
response , performance and car upkeep. It
has full service history maintained by the
agents. Only 96000kms only on the clocks.
The reason posting is cause I've received
the diagnostic report, and im not entirely
sure how to read them, but it seems that
there were some things that showed up on
diagnostic and not in as they specify in
normal error parameters. Does anybody
know how to read these , understand if it
means the computer detects problems ..
The car aski in test drive , seemed always
pull of is second , is this normal?
Economical ? When the stronic is activated
and it manuel operated it starts off in 1st
