By reports here, car engines seem to lose oil at a greater rate (i.e. quarts/mile) now than 10-15 years ago. Part of the reason I expect is a tendency toward higher-performance turbo designs in order to achieve the car-selling points of both good mpg and good power. So perhaps your Q7 has a high performance engine; likewise, higher performance engines require higher performance brakes, and those tend to do what you describe, squeaks and brake dust. Timing chains experience higher forces w/higher performance engines, especially with a driving style of rapid accelerations. So earlier failure isn’t unexpected. AC evap drain clogs aren’t related to engine design so much, but are a common complaint here among many makes/models. You can see what others have said by using the forum search feature, link above right on this page. However a higher repair fee to fix this problem is expected for a higher performance vehicle, b/c space tends to be at a premium and the parts tend to be all crammed together in order to fit, which causes the mechanic to take longer to effect the repair. --- _[View the full topic](https://community.cartalk.com/t/2014-audi-q7-just-these-four-problems/179359)._
