Congrats man....awesome you were able to DIY. I've had at least 3 regulators go over the 2 X5's we've had (our 2001 3.0 had 2 for sure, and one on our 2006 already). What a pain. Glad to see you were able to do your and fave a few bucks.

I believe there's a bit of a mod that strengthen this common failing part.

Good luck!
