I was wondering if someone could check the front of their C for me on the air dam. The top vent on the passenger side front of the car looks like a cover or cap is missing from the top vent air dam. In the middle of the vent I have an open circle about the size of a quarter. I brought the car in for its first oil change earlier this week and while looking at the invoice that was provided it also states that they oiled the chasis on the car. I wonder if this was done via this hole and the cap was not placed back. I'm pretty sure I would've noticed this before as I have washed the car multiple times and have never noticed the hole before. It seems like a coincidence that it is missing right after I brought it in for service. Does anyone know what this hole is for and if it should be covered? What if any damage can be done if its not covered?
