Altea XL 1.6 tdi SE Copa 7DSG -Advice / experience sought.

[Valuesman]

Hi everyone,
Just joined and dont even own one yet...but.... Just placed a deposit on 13 plate Altea XL.
Before I make the final commitment, any things I should ask for them to do / check / resolve.
Its from a Seat main dealer - 1 owner 19k miles.
Simply love the DSG drive but does set of nagging doubts in my mind about potential repairs.
Any feedback greatly appreciated
Cheers
