Hi MCFers,
Has anyone experience foul smell or exhaust fumes seeping into car aircon system? My aircon setting has been set to internal circulation which means no external air should come in. But i notice whenever i tailgate behind those big trucks, i could smell their exhaust fumes. Another occasion when i travel along Hougang Ave 2 where there is some sewage works going on, i could smell those drainage odour in my car.
I'm driving a COE car.
