4D16 code and MIL, 121,600 miles
I just had my CEL/MIL come on my 2012 e70 X5 35d and am at 121,600 miles. From my reading of the 4D16 code, NOX sensors or the SCR cat are strong candidates for being the problem. Hoping there would be some flexibility in the 120k extended warranty for these I called my local dealership and they told me there is nothing they can do. Curious if others have had same experience as I recall BMW will sometimes agree to honor warranty when so close on a goodwill basis....
Assuming I can't get it covered under warranty, I think I will try to throw a couple NOX sensors at it and see if it fixes the problem, unless others advise differently. Reading other threads implies this is the primary cause of this code and while I had throwing parts at problems these seem like a wear part that likely will go soon anyway even if not causing my problem today. Not ready to consider a delete. |

Go to a different dealership, you are just past the 120k and still within the 10 year.
NOx sensor is definitely covered, and my guess is the SCR is as well
