at about 160 miles on my f7 the tempature light came on. I felt the motor and it wasn't hot and the right side heat exchanger wasn't hot. so i figured i had an air pocket in the system. so i went threw the process of burping the sled and the light went off. now at 280 miles the temp. light came back on. I was out in the middle of know were so i stoped and did the burp process again and let the sled sit for about 1/2 hour. started the sled back up and the light was still on, didn't have a choice but to ride it home. after about 10-15 miles the light went off. why does the light keep coming on and should i be worried that i had to drive it when the light was on??
