My a3 is due a service and is due and DSG oil change. From what I have read the DSG oil and filter should be changed. I was thinking about getting the DSG change done at audi or VAG specialist as it really needs to be done correctly. Then I was looking at getting the service done independently. Is the filter that is changed with the DSG the same filter that would be changed on a service? My point being that obviously there is no point getting two new filters within the space of a week or so.
