I just had my 10k done at the dealership and thought I would share. The service advisor told me that the oil they use for the tdi is kept in bulk(I asked for the container with the left over .5 qt). From everything I've read about 507, it's only in containers. Another service professional told me that any oil in their 500 family will do for the tdi. To top it all off, it was overfilled. I plan on calling VWOA on Monday; am I over-reacting? I feel that I need this whole thing documented incase they used the wrong oil, and I have a problem later down the road. Also, should I insist they tow the car instead of driving it back to the dealership?
