After 200$ the problem was NOT fixed, the light came on again every time they reset. I originally bought them because they are "OEM" but they don't work properly and the light comes back on. I did a manual system reset twice (according to the manual) and after that failed I went to Pepboys and asked them to reset them with a scanner. Nothing works. Just wasted a lot of money and time getting nowhere. And there was no product support or help. death s
