My 03' R50 has 110K miles on it. Recently, the fuse F3 15A blew and I replaced it. Now, after 3 weeks or so, the fuse blew again. I got the usual 8 different codes and the check engine and DSC light was on as well. I replaced the fuse, reset the codes and all is good. I also replaced the O2 sensor, the one by the cat. I did not do anything with the one behind the cat. I am afraid this issue might come back again...

I am not sure what else I should check... Any help would greatly appreciate it.

Jay.
