Don’t bother. The fix is only temporary and doesn’t make much difference. Best fix is to spray silicone spray inside. The door button will fix itself over time once it’s worn in. The Grenadier gets better overtime.
Worst thing, is to get the dealer to open up the door cards, rip open the vapour plastic barrier and change the door button. The door is never the same with rattles and loose clips or missing screw. I had one door done and eventually I had to open up the door card myself to discover a missing screw which I later found at the bottom of the door rattling away.
