Hi, I have a 1997 300tdi. The brake warning light is not coming on at startup (the test it does). The low level switch is working but the hand brake switch isn't, I am not sure if that's connected to the fact the start up test is not happening. I know it's not the end of the world but would like to see if I can fix it. Any ideas of where to start? Is there a relay for this lamp flashing at startup?
Thanks!
