I have a 1986 325e and have recently noticed my brake lining light will come on intermittently, no biggie, I probably do need brakes, but what baffles me is that it only seems to come on when my temp guage is "pegging" from cold to medium. Sometimes after I go somewhere like into a store after its been doing this when I start the car again it will act normal. Could these 2 problems be related in any way? Any advice or input would be appreciated.
