they appear to be metallic on my 2016. try a 5.5 mm socket wrench.

does everyone with adaptive cruise have the lower grill covering the radar or is it open? 

You have no idea how much I appreciate this forum and appreciate you. This community is a lifesaver. 💗

I got a message today, after my Edge wouldn't remote start, that the battery in the fob was low.  Yeah, so low, it wouldn't remote start.  I could still unlock the door though.  Got the other fob, and as I figured, it was dead also.  Luckily, I had some CR-2025 batteries at the house.  Of course I didn't know that each fob took two batteries.  Dang.  And man, getting the cover off was a test of patience.  If I had to get to the emergency key for something real, I think I might have broken the thing.  After it broke my fingernails!!  Anyway, I finally got them apart, changed the batteries, and all is good.  Now to get the second TPMS sensor replaced.  It's close to oil change time, so I might just wait until that comes up, or just get the oil change done a little early, and have the TPMS done at the same time.  It's all good!

Welcome.   What type things does your Edge need doing?

Hi all, I'm new here from Lubec ME. I've been a lurker who only visit the site whenever i need things done with my ford edge 2010. But I've decided to be a full member and to connect with fellow enthusiast. I'm welcome to learn more about my car and to share ideas if needed. Thank you all! 

FYI, in case you didn't already know, the ATC is sold separately, in case the differential is good and you don't want to replace the whole assembly. 

As far as I know, A/C systems on Ford vehicles come with the dye already inside the system from the factory. So leaks can be detected faster.    This is from the 2015 Service Manual, but I would expect it to still be the same.  Fluorescent Dye Leak Detection.pdf

Pulled the plug, made no difference other than throwing an AWD malfunction error.

Yeah, I unplugged it, threw an error on the dash, but didn't change anything as far as driving. Wheels acted like trying to grab on pavement when turning... as if it's in a 4WD in 4WD.
