Not sure if any of you have this. I'm getting a fast, almost fuel injector sound ticking that comes ago as if it were a flick of a switch. I believe its coming from outside, although It sounds like something on the passenger side. If I open the door I can really hear it. It happens at any RPM, drive or in park, does not matter. Killing me. Going to bring it in most likely. It just started happening. I've got 50'000 kilometers on the car.
