Friends, last week, I had just started the car this morning and was driving for about 3-4 km in stop-and-go traffic, and suddenly I heard a noise like a bed knocking. At first, I thought the sound was coming from far away. I even thought there was a concrete breaking truck or something, but it was far away. Then I realized the sound was with us. It didn't take 5-10 seconds for the sound to disappear. My friend next to me said the bed knocking sound. I first suspected the transmission, but now I suspect the injectors. It hasn't recurred in a week. But there's a clicking injector. I can hear it clearly, especially when passing close to walls. I'm also wondering if it could be the rail sensor. I haven't had a chance to see it yet.
