Asked by GuruTFN5S Jul 20, 2018 at 08:28 AM about the 2015 Audi A3 1.8T Prestige Sedan FWD

Question type: Maintenance & Repair

My audi a3 2015 Se has some form of oil leaking from the passenger feet aircon' it comes from underneath the passenger dashboard.
the engine is free of any oil and no oil leaks from the engine.
what could be leaking, it is clear oil like fluid, with no smell to it?

1 Answer


The only kind of oil that would come from that location would be Air Conditioner Refrigerant Oil, coming from the A/C evaporator. This oil would be very clean and clear. This means an evaporator leak. That means the refrigerant is also leaking and I would guess your A/C is no longer working. Assuming there is not a bottle of baby oil in the glove box leaking, you have a broken A/C system.
