While taking out the G263 sensor I took out the foot vent (black plastic 'box') and had a look inside. It was quite dirty, with what appeared to be soot. Has anyone had very dirty vents before, and how did you clean them? I don't really want to pull the whole dash and air-conditioning/heater unit apart.
I am also at the beginning of the process of finding where a nasty smell is coming in from. It smells like exhaust/soot.. I have to fix the drains under the bonnet to make sure they are not open all the time (depends how far they are pulled onto the plastic? one isn't quite glued, and perhaps it's stretched on too far), and to make sure that the small one near in the firewall is there. I also want to check the exhaust vents/valves in the rear of the car. Is it possible to do this from the inside, by removing some trim perhaps, or does the bumper have to be taken off the car?
Could the evaporator or heater or anything else inside the hvac unit be dirty and causing this smell to persist even though not new pollutants are coming in from the outside? Can the evaporator unit be vacuumed? I plan on checking its drain hose and outlet to make sure it is clean and functional.
Can a biocide for the evaporator help with any sooty/exhaust smell, or would it only get rid of mouldy smells?
Is there any hope for the air inside to every really be clean? even when idling in traffic?
Thanks in advance for any help.
