Was doing a little work on my E9 today and had to make a quick run to the auto store to pick up a few things. On my trip back the "T" light came on the instrument panel. My first thought was "Dang it Mike now what have you broken". I had a 3.0CS owners manual a friend gave me but no reference to what the "T" light indicated. Quick search to the e9coupe forum revealed low on gas. What a relief not something stupid I broke! By the way what does "T" stand for?
