So, when we were replacing my angle gear sleeve, we hit the little, round plastic vent cap and it broke and fell out. I planned to stop by the dealership and track another one down (and then figure out some way to get it on there.. PITA.) but ignored/forgot it until now. I was too excited to have AWD drive to care..
Super important, "wrecking my angle gear as I drive" part, or just get it replaced soon.
Finally, the question I'm really worried about. Will Volvo even sell me one? I didn't see it as a part in the online catalog..
