I just sold one of my 400E's a 92 model. The radiator and cooling system was flushed using BG products about 5 months ago.Th guuy who bought the car says that the low coolant level light comes on very lightly at night even though the resevoir is full. I believe that the problem is the sensor. Before I offer assistance does anyone else have any input.
Thanks
Alan
