Hello all, I'm new here and searched for this topic but didn't see one that hit all the points I wanted to learn about. If there is one that I missed, sorry in advance. I have recently been looking at a used 2008 Audi S5 with the 4.2L v8 in it. It has 90k miles on it and is listed for around 15k. I just want more information on the potential timing chain issues and if I should be worried about them. The car has a maintenance history and clean Carfax and is really tempting to buy after I test drove it. I just do not want to get stuck paying a large sum of money to get such issues fixed right after buying it. Also if there are any other issues that I should know about please let me know. Thank you all.
