Does the SULEV emissions warranty cover coils?

A few months ago, a VCG leak caused a secondary air system fault code, and BMW fixed it under the 15yr/150k SULEV warranty (California car). This morning, I started the car up to find a misfire on cylinder 4. Best guess, given its persistence and the car's age (113k) is that I need to replace the ignition coil. But I'm also getting a secondary air code again. I'd assume it's a direct result of the misfire, given that secondary air operation seems to be determined entirely by O2 sensors - but what do you think my chances are of getting it covered under warranty?

EDIT: Could have searched better on this one, looks like the answer is a very likely yes: http://www.e90post.com/forums/showthread.php?t=1324089
