After I parked my car, I found a black, dirt encrusted warm part on the driveway that was on the path I had just taken. I have the part number, it's a part for the engine I suppose, since it begins with 617. The whole part number is 617 014 04 33. What is this part and its function? Is it safe to drive without it?
