Hi all, My first post, so please bear with me. I have a 2013 Audi RS5 Convertible, which is my most recent Audi over nearly 25 years of ownership. I bought it last year and it's coming up for it's first inspection service in a couple of weeks. The only issue that I've noticed recently is a slight oil weep from the part in the attached pic. There are obviously two, one for each bank of the engine. Please excuse my ignorance, but can someone please tell me exactly what this is? The oil leak is from where there is the only connection on the part, horizontally. It's only a slight oil weep, but naturally I'd like to get it checked out and sorted out. Thanks for your help in advance!
