I had two failed injectors as well on our 2015 35d. Had BMW here in San Antonio replace them early last year I think it was and paid out of pocket. Contacted BMWNA and let them know about it, but got the same response you did, which I was expecting. Hopefully they add 2015 35d's to the injector extended warranty issue and I can get reimbursed at some point.

Good to know parts are available for the EGR recall. Will make an appt for the X5 as soon as I finish (start) the brake job.
