Yep I'd say the local importer had been into the doors as they have to weld in side intrusion bars to make the VX comply in Oz, as low vol import..
...the parts so small its probably dropped out when doing the work, and they just put it together probably thinking geez thats doors noisy..but not my problem..my temporary fix seems to be good so far..I'll see how it holds up over the coming weeks whilst I chase down the correct part..
