The 2011 1.4T is known to have an issue with cracked pistons, but I don't know as there's any extended coverage for it.
As for being worth it - I'd suggest checking KBB.com and some other sites to see what the trade-in or private transaction value is. I did a quick check for a LT of your mileage in "good" condition and $4000 trade-in seems do-able.
