I am trying to program brand new MX (433MHz) sensors installed onto a second set of wheels for a 2016 Mercedes C-class. I manually entered the ID (clone the stock sensors) in programming mode, but get an error that says "write file error (-1)". It appears to at least find the sensor, because if I try very far away from the wheel, I get an error "without sensor (-2)".
Can someone help me? I tried this after driving for about 30 minutes. How do I activate (wake up) the MX sensors so that I can program them?
I am using a TS401, with software version 5.41. Thank you,
