Question about Cars & Trucks
Have a coolant pressure test done to determine for leaks in the system. have a compression test done to determine head gasket or cracks.. Check radiator cap is holding the set pressure and is opening to admit water back from the reservoir on cooling. Check hose from radiator to reservoir is tight with no cracks in it.

SOURCE: 'low coolant"
Inside the surge tank is a float that turns on the "low coolant" light. As the float gets gummed up it gets stuck in the low position. I've had good luck in cleaning the surge tank out really well and ungummed the float so it slides up and down like it should.

SOURCE: Low Coolant light
Sounds like your sensor unit in your coolant overflow tank. Like nearly everything man made that floats, they will eventually leak (become water logged). This is a relatively cheap fix, as long as the light is coming on and the coolant level in the overflow tank is between the MIN and MAX lines in the overflow tank. This means that the float in there is dropping below the actual fluid level (watter logged) and you need to get a replacement sensor unit (aka sending unit) for the overflow tank.
Otherwise, if the coolant level in the overflow tank IS BELOW the MIN level line on the tank, then you are losing coolant somewhere and that is when things start to get expensive (might be a radiator problem, head gasket, cylinder head, heater core, etc).

There is a lot wrong with "low oil" and low oil is not normal in a low mileage healthy engine.
The dealer is fobbing you off in the hope you will go away.
If the oil is being changed at least every 5000 miles or so there should be minimum oil depletion between changes with only very minor top up needed. Some oil consumption is normal but it should be minimal.
If the oil level is dropping to a very low level in about 4000 - 5000 miles of normal motoring you have a significant problem. The oil is either leaking out or the engine is burning excessive oil or a combination. If there is no leak through faulty seals or by other means such as oil escaping into the cooling passages of the engine, then there is excessive burning.
These engines are known for excessive oil consumption because the problem is a common one in the 06, 05, 04 and previous year builds back to about 98/99. The dealers know all about this problem - as does BMW - and they will try to fob you off until the car is out of warranty because the fix is expensive.
From what you say the problem has not been fixed on your car. Document the oil loss and insist on your warranty rights because your engine is using excessive oil and this is NOT normal in a properly functioning motor with as few miles as yours has. Make it clear to the dealer that you are well aware that excessive oil consumption is a common problem in many of the 325 petrol engines and you want it fixed under warranty.
Then sell the car as these vehicles will cost you quite a bit in repairs once out of warranty and once you clock up around 60000 miles or more. If you have an auto you can expect major problems at about 65000 miles (later if you are lucky) and replacement of the transmission will be necessary. Once you notice any significant problem with the auto transmission it is on it's way out.

more than likely is being caused by a faulty level sensor but first check the connection and fluid level when engine is cold as fluid level will rise when engine warms up

Hi! Please check the coolant reservoir for it may need to be filled up a little. Hope this helps and have a good one!
