I have been doing a major overhaul on the top end of my 2006 BMW X5 e53 4.8is. It's been a nightmare by the way, but I won't bore you with those details. I just have a question. As I was taking off one of the valve covers, I slightly cracked one of the cam positioning sensors. It doesn't appear to be a serious crack, and I could probably repair it. Do you think that cracking it damaged it's functionality? I can post pictures later if that would help. It cracked slightly right where the upper cylindrical part of the sensor attaches to the lower square part. It was a small diagonal crack. It appears that it is only plastic that cracked, nothing electrical.
