I also found some motor oil in my hoses and dripping out the bottom of my intercooler. Seems normal as the engine runs good with no black smoke. In comparison, I had to replace a blown turbo on a Mercedes turbo diesel truck engine in 2005. Everyone thought the engine was shot but I found a large amount of oil in the hoses and intercooler. The operators were adding a lot of oil and the engine was blowing black smoke. It's easy to jump to conclusions that a turbo is shot when we find oil in the hoses or intercooler. As long as the engine runs good, has clean exhaust, and we don't have to keep adding a lot of oil, the turbo should be good. My son has a 2008 VW GTI and it uses a small amount of oil between oil changes and it runs great.
