I recently bought 2009 E92 with 87k miles on it. The dealer said the display will indicate when the service is nearing. When I did the check the display shows the next service for 4200 miles. From the service log I know that the last owner got it serviced 20k miles ago.
Though I don't see any major problems please advise if it is okay to go by what indicator says or is it better to get it serviced every x no.of miles?
