2013 Passat Alltrack purchase

[staryknight]

I Just put a deposit down on a 2013 Passat Alltrack with 107kkms on it. Price was $19400 and it's got the sports pack and driver Assist and visibility package.

I'm waiting for the used car dealer to show me the servicing records and the most recent 105k service done with timing belt replaced as the books weren't there when I went in to test drive and put down the deposit so I'm anxious to whether it's up to date with all its servicings.

I'm finally going into something more sensible and family friendly after owning my scirocco for 5 years.

What's the best TDi tune going around nowadays for the 2l diesel and is a DSG tune worthwhile? Coming from a manual scirocco it's quite a different car. Also do people install oil Catch cans I'm their TDis or even do the EGR Valve delete?

Edit: purchase fell through and the dealer couldn't supply full servicing records so I got my deposit back after some drama and have just signed to purchase a 2013 Audi A4 allroad.
