Second issue that cropped up on our trip last weekend. The parking brake switch has come adrift. It's not totally loose, but has started to move around. Does anyone know how this is attached? Next time I'm at the coach I'll bring a bore scope and go in through the cup holder but if someone has experience with this issue I would like some guidance.

Thanks,

Mine came loose on my 2018 Phaeton and you will have to remove the panel it is attached to and get in there with a large wrench, 1" or 11/4" to tighten it. it takes some maneuvering to get to it. Good luck..

Mine was that way when we did our PDI at delivery. The dealer removed the plastic panel covering and tightened it. It worked loose over a year ago and I've not bothered with it. It's still secure the way it is, it only moves around in the mounting hole and does not affect the way it works. If my roundtuit ever comes in I'll get around to tightening it up again.

When I tightened mine I put a drop of locktite on it so I wouldn't have to do it again.

So is it captured in some type of bracket under there? My fear is that it is going to come loose completely and I won’t be able to release the brake.

This discussion finally convinced me to get roundtuit it and tighten the valve. First remove the ten screws around the black plastic panel. Next you will have to use a small punch or screwdriver to knock the roll pin out of the yellow knob holding it to the valve. It takes some pulling and contortions to get the panel away from the dash and lifted up enough to get to the large nut under the black plastic. The valve is mounted through the plastic side compartment underneath the black plastic and really the likelyhood of the nut completely loosening is very miniscule. Even if it did, the valve can't fall through the hole due to the size of the knob. I used a large pair of pump pliers to tighten it and like posted earlier, put some LokTite on the nut to hopefully keep it from loosening up again. Lastly I used the same pliers to squeeze the roll pin back in the knob and valve shaft.
