the def system in all diesels is a huge issue at the moment. if the check engine light is on with the remaining starts light then there is an issue with the adblue system, there have been tons of issues with heaters and level sensors. this system is still not perfected and is very troublesome, consumers are better off with gasoline issues, as the expense of the adblue and repairs outside of warranty will negate any fuel savings that are advertised. i will not be able to tell you what is wrong without fault codes, you do however need to see a dealer asap or the car will be locked out of starting after the 16 starts. they need to get this rectified sooner than later, hope this helps, Lou P.
