DEF flush for X5-35d no longer covered/required?
My 2011 X5-35D is 1 year old, so I just took it in for the oil and DEF change. From what I've read here and elsewhere, they flush and refill the DEF as part of the regular oil maintenance. However, they (BMW of San Francisco) only topped off the DEF. When I asked about the DEF flush, I was told BMW has changed its policy and the DEF is no longer flushed under the BMW covered maintenance program, only topped off. Did I miss the memo, or...?
