A couple of my parking sensors were sitting a little askew, so I figured their holding brackets had probably come loose.
As we discussed earlier in this thread, VW has a bespoke tool for clamping these down while the epoxy sets (part of the VAS 6614 set of tools).
#6 is the plastic bumper cover; "a" is parking sensor bracket on the inside of the bumper cover that has to be epoxied to the inner bumper cover (epoxy is #7).
When I installed the other sensor brackets, I was able to get a clamp onto them in some way and they seemed to be holding solid just fine. These two in the middle, though....I just put some weight on them and hoped for the best....which lasted not quite two years.
So, wanted to do it better-er this time around.
I called my guys at the local VW dealership here to see if they had one I could borrow, but they did not.
Time to get creative: Being Canadian (and as required by law), I had a few hockey pucks kicking around the garage. So, I figured a way to re-purpose a hockey puck along with some Goop™ to craft my own version of a VAS6614. Did the trick very nicely.
And on the outside of the bumper cover, some rubber and a couple heavy washers.
