I'm at 68,000 and never got the perform service for this. I have changed the filter twice though. 1st time very oily. Second time after J35 could have gone longer. Even though I have no service light I think I will make an appointment next week for the EGR service. The 2 dealerships I work with have a 199.99 deal.
