BMW Repair: bmw dash board symbols, bmw 325xi, water jug

Question
What does the red box that looks like it has water in it mean. I have a BMW 325xi 2005. That light has come on a couple of times when I start the car over the last few days.

Answer
The red light that looks like a water jug is oil pressure.Check your oil.If the oil is low you must check out why.It may leak or burn the oil.You should have the oil pressure checked to make sure it is fine,as you may have a bad sending unit or engine problems if it is low
