Anyone able to help with buying advice for a Touran?

Hi guys,

Hoping someone on here can help as I'm struggling to get any replies elsewhere online!

I'm looking at buying a VW Touran, 2nd facelifted version so 2010 onwards. It's the first time I'll have had an MPV.

The examples I'm looking at are mainly the 1.6TDI - the only other one we'd consider is the 2.0TDI as we don't want a petrol. They've mostly done 80 - 100k miles.

Just wondered if anyone could offer any buying advice? Was the 1.6TDI affected by dieselgate or does it have any other known issues that I need to be aware of?

How do running and maintenance costs compare to something like a Golf or Octy estate?

Any advice gratefully appreciated as I may go to view one this evening.
