im new to this forum but I need some advice from fellow Audi owners please. I have had my a5 cab tfsi 2lt 2012 from New with full Audi service history. For a second time my pistons have failed and Audi have now put in a brand new engine with a 2 year warranty. This was a 10k job which I had to pay half. Before this happened I was contemplating changing it but how would this now affect the value of the car? Should it be worth more or less? The car has 50k on the clock with now a brand new Audi engine as of last week. Any advice would be really helpful.
