Good day, guys.
I have my 2007 aurion serviced a few months ago. When I open the engine hood yesterday, I found one small tube near the air intake is disconnected(Please refer to the photo attached). I sent the car to the mechanic who serviced my car, they said they didn't know about it and blocked the tube by some screws. They said it is not important and I still can drive until I find something strange. I am a bit worried about it, can anyone please tell me what the tube for? and should I get it fixed, the mechanic said it would cost a bit as they have to change the whole part of something.Cheers.
