So I just passed the 6K mile mark on my 2016 TD6 and I am getting a service required message. In vehicle info it says that I am due for an oil change, which makes no sense since the first oil change is supposed to be 16K miles or 1 yr. My vehicle was delivered in early February 2016 and built in early January 2016. Checked oil level and it is reading only 1/8 below full. DEF says fill in 3,500 miles, which is about right. Any ideas?
