My car is about to be 2 years old, and I am worried there 2 items could be already letting go, since it is a common fault on the 2.0T engine, specially on the GTI´s. Has anyone changed either of these items on an S3? If someone can throw me the part numbers for these items (specially the PCV and PCV tube) I will really appreciate. I am in the process of updating my car a bit, going to install some BBS CH´s, lower it and put a milltek turboback.....so I want to make sure it performs at best. Thanks!!
