Well just like the title says, my battery light is on, my battery shows like 12.6 just sitting there and 14.1 when the motor is running. revving it up does nothing to the light. New to this car, new to the TDI game, not new to VW or wrenches but this is my first water cooled VW. Bought it cheap (1997 Passat Wagon) looking forward to playing with it and getting that mileage. Just working out a few kinks before my timing belt kit shows up. I'll get a new TB in there and start driving it!!! Guess I should also add...I have a totally dead instrument cluster...no LED, No tach, no speedo, but I figured these lights were a seperate deal since they seem to work .
