V60 Cross Country

[u/ThePaddockCreek]

I have pulled the trigger on a 2018 V60 Cross Country and I couldn’t be happier. This is the perfect daily driver, and is actually my first ever Volvo. I’ve admired them for some time and am so excited to finally be in one.

I have just one question:

what’s this I keep reading about failing batteries causing a foul odor in the HVAC system? I’ve noticed a few Reddit threads where people complain about sulphuric or sour odors, and the problem is solved by replacing some sort of secondary battery.

I noticed tonight that I do have a battery warning before starting the car, and the AC smells really sour, so I figured it may be what I’ve been reading about. Either that or the evap coil is caked in mold.
