I was changing my o2 sensors and found this underneath my 96’ C4 when I was finished. I couldn’t find where or if it came from my C4. I’m not receiving any faults. Anyone have an idea?
If the tab(s) are busted you can buy the drain tube separately. The source I was quite familiar with doesn't seem to have it any longer but I'm sure there are vendors out there.
**** I found it for as little as $1.20 but who knows what their minimum sale is or what shipping might be. Maybe you consider doing a solenoid tune up and adding the vent to the purchase.
Anyone know what this is?
