Seem a few people talk about some sort of dme software update that helped. Any ideas ?
I had the knock sensor before, a new sensor fixed it. I think the sensor code indicates that you have a bad sensor...if you had knock you would have a knock code...
Unless a faulty sensor can make knock's 100% knocking
