I own a 2005 S4 with 127k miles, and a month ago it began to drip oil on my garage floor (about 1 drop/night), the engine also began to burn about 1L of oil/1000 miles a couple of years ago around 100k. I'm going to take it in to my local Audi dealership Tuesday to get a diagnosis, and will then take it to a trustworthy friend of my neighbor's who owns a shop that specializes in BMWs but works on all European cars. Any ideas on where these engines typically leak oil at this point in their life? I was also considering having someone do a carbon buildup clean, as I fully plan on taking this thing to over 200k. Also, are their any services I should inquire about regarding any heavy-wear components that should be addressed at this point?

Thanks.

I forgot to mention this car had the valve cover gastket(s?) replaced at 50k miles due to it dripping oil a fair bit worse than it is now.
