Well just had a call from VW Boston the leak is fixed, turned out to be the seal on the pipe that goes into the main air intake and another part from the fine oil seperator, £227 altogether. They didnt charge me for any of the diagnostics or fault finding, so it could have been a damn sight more.
Now the task of speaking to VW UK to find out if i can get any sort of goodwill seeing as Maidenhead VW identified something in June, when it was still under warrantly and said "it was normal to have some oil seapage around the air intake pipe" seems like that was an easy cop out by them.
But im glad since i moved i have found a very good VW dealer, which is a pleasant surprise.
When i get the paperwork later i will have a look to see if there are any part numbers on it, and hope the leak doesnt reappear in a few days, fingers crossed.
