I'm considering buying a 2015+ A4 2.0t and i'm look for everyone's opinion regarding long term reliability. I have owned a 2001 A6 4.2 v8 and a 2006 4.2 v8 and both had many a few very pricy issues that has scared me off from Audi for many years. I loved every minute of owning these cars but the cost for repair was beyond what i'm willing to deal with again if things haven't changed. My biggest concern is that there was a point around the 80-90k mile mark when i had the major issues start. The 2006 model i had and apparently the couple years to follow,had the dreaded camshaft position sensor problem that let to an almost $9K in repairs around the 90k mark. This causes major knock and massive power loss due to a poorly designed part in the cam (sorry for not knowing the specifics) which required the entire motor to be removed from the car to repair the timing chain and something related to the camshaft. I understand there is common maintenance with every vehicle, but needing even a $2k repair at 100k miles is ridiculous in my opinion..
Is there anything I should look out for if i'm looking to pick up a used 2.0t?

 

Up until the 2012 model year there is an oil blowby problem that is very annoying but not fatal. After that it should be just regular maintenance. I bought my 2011 with 99,600 miles and have run it for almost 40k with minor issues (needed rear strut assemblies). Just returned from a 1800 mile trip MI-SC-MI and it returned 28-30 mpg.
