I'm in the process of putting together an 2016 Audi A4 B8.5 s-line and I think I've got everything sorted except the front impact sensors and what I believe to be the hood closed sensor. Could someone post a picture of where these are connected? I've checked the audi.7zap.com reference and I get an idea, but it's not specific enough.
Of course as soon as I ask for help I figure it out So the clicky thing was the hood latch sensor and I found a video of a dude talking about it... just had to take the latch off the radiator support and there were two holes that the micro switch lined up with and it clicked into place... easy peasy...
Now with my confidence up I started looking around for where the crash sensor might go and sure enough I found it on the support bracket below the headlights!! Two for two!!
