Hi, My A3 is due its 2nd service within the next couple of months. The car will be sitting at about 33k. I believe the DSG/S tronic oil is recommended to be changed every 40k miles. Seeing as my following service will not happen until about 50k (going by current intervals) should I get the oil changed now at 33k? This will save a visit to the dealers at 40k. Also do you know if the DSG/S tronic oil change is included as a normal part of service? Thanks in advance.
