I can only speak for myself, but the pinging I experienced pre software/knock sensor update was so Minor & infrequent I could have lived with the problem. At no time did I complain to my dealer about it, if not for their insistence that I return it for the update I would not have done so. I have driven more CU2's than i can count & have not noticed a severe pinging problem on any of them, it is more like very mild & infrequent, you really need to listen for it & it usually last for 5 to 10 seconds, mostly between 2000 & 2500 RPM
