Yeah, not what you want for this. The price is the evidence but also if you read the description it has no reference to the BCM. I recommend calling a dealership service department and carefully ask as many questions as you can. Generally the answer will be that you'll have to bring the car in but you never know until you try by asking - with some thick skin..

I hope you don't think I'm stalking but you are asking a lot of good questions to which I'm interested in learning the answers.
