Trans Failsafe Prog -- Now dead Battery -- What is going on?
Day 1: I started my 2001 540i in the morning Trans fail safe error came on along with other dash lights. I drove it about 3 miles (using only 3 gear apparently). I parked the car for an hour. It started fine and drove fine but the battery light was now on. I drove it 3-4miles and parked it.
Day two: I drove the car 5 miles to the store. The battery light was on, the car ran fine. At the end of my trip the radio signal got weak, the interior lights got din and the windows closed slowly.
Day 3: Car will not not start. Interior lights come on but it will not turn over.
Does anybody have an idea of what is going on? I am thinking my alternator or battery are having problems. Should I be worried about the transmission?
What should I expect when I take it to a mechanic.
Any input would help. Thank you very much.
