I have a 2012 1.4 turbo with 150k highway miles... relatively trouble-free for last few years... recently changed water outlet, but reused coolant line back to reservoir...long story short, that blew apart, coolant gone and car overheated. Pulled over and shut off immediately... fixed hose and refilled, but exhaust gas bubbling through coolant tank bottom hose. Mechanic wants to install new head gasket, machine the head if it's not cracked, new water pump, and new timing chain. $3k. New engine is $6-7k or I can try getting a salvage and do it myself (he won't put in used engine). Anyone else had this problem? Shame to scrap this car, but I'm pretty close.
