Started getting a smell similar to stinky feet a couple months ago out of the HVAC system. It has become more frequent and stronger now bordering on smelly feet dipped in doggy doo. Besides being unpleasant it's also embarrassing and certainly doesn't impress non-Tesla owners/potential buyers. I've tried turning off the circulation, tried turning off the AC 5 minutes prior to stopping, tried setting the temps low, high, blower high, low etc etc. with the only solution being to not run the AC and just roll down the windows. Have an appointment set to change filters and spray some solution into the system but am being told it may return. Has anyone experienced this and if so, found a solution?
