Hi,
The issue is in the air tube.

What could be the cause?

Hi there,

Are you referring to oil being in the air induction hose that connects the air cleaner to the throttle body?

Hi there,

If you are getting a build up of a thick sticky deposit at the butterfly valve this is normal, well not normal but something that happens with fuel injected cars, you only need to clean the throttle body and valve with throttle body cleaner, just spray and wipe away, this should be done at every service so i dose not build up,
