Tiguan DSG troubles !! Oh Dear I thought this might happen!

[knoffie]

Purchased a 2013 Tiguan in April 2014. After worrying over reliability issues and cost of repairs and a lot of help from this forum I decided to buy it. Has been trouble free ( 87,500klms) until last week when I took it in to Southern Volkswagon for its last service under the warranty.
I mentioned that it had developed a clunk when lifting the throttle off and on in the lower gears. After test driving it they agreed and the DSG has to come out next Monday..They will need it for three days!
Now I am so very, very glad that I mentioned it, but now I am afraid to keep it! As I have recently retired and on a pension if it goes again there is no way I could afford to repair it. What do I do? Some options:
1. I could trade it in on something that is less expensive and no major issues, e.g. Mazda CX 5.( drove a 2012 model..didn't like it much)
Hyundai IX 35, Kia Sportage etc. Looks like I could only get around $19/20K and take a $10K hit.
Or take out some extended warranty policy? However Allianz want $4,100 for a 4 year extended warranty.
Swann , around $3,100 for the same type of warranty.
Or just don't do anything and hope like hell nothing major happens in the next 4 years or so.
I really am in a quandary. My wife and I love it to bits , but I have been warned by many that " it will bite you eventually"
Are those warranties worth taking out? If so which one? Any experience?
Any advice would be appreciated ..and yes mine got caught up in the recall! Buggar! Just something else.
