2011 CR-V odd smell diagnosis help    (Score: 1, Normal) 03-21-2019 21:13

2011 with the 2.4l k24, 85k miles

I've recently noticed that my CR-V would occasionally produce and odd smell, musty-ish. It usually occurs after slowing down from a brief moderate/hard acceleration.

I've done some basic diagnostics. The cabin filter is clean/new, no foreign debris. The smell is only occurs when recirculate is off. A/C on or off doesn't matter. So it makes me think it might be coming from something else in the engine bay and it's being sucked in by the the climate. I've visually checked under the hood and noticed no odd smells. All fluids look fine.

Maintenance has alway done on time according to the MM system. Did a 3x transmissions drain and fill the last oil change. The A/C compressor and condenser has been replaced by the dealer under extended warranty before when it shat itself a couple years back. Other than that, no major work has been done.

Anyone dealt with a similar issue before? I had suspicions on the alternator (i noticed it would take an extra .5 seconds to fire up on occasion) but the battery and charging voltage seem to be fine. Any ideas?

I would guess you simply have mold or mildew in your HVAC and that's causing the smell. Fairly common.

Here's a video showing how to cleanse and remove.

This is exactly what I was thinking.
