2003 BMW 325i will start but making noise

I have a 2003 BMW 325i. The vehicle starts but as I drive the engine makes a loud noise when turning the steering wheel to the left or the right. I can start the vehicle and turn the wheel from side to side and it makes this awful noise.

    I checked the level of the power steering fluid and it is full.



    When moving the steering wheel side to side while stationary the noise is present. Also I smell fumes when I start the vehicle.

    Thanks for your assistance. The mechanic picked up my car today and the power steering pump had to be replaced. Good job!

It might be a faulty power steering pump. Try checking the level of the power steering fluid. It is probably best you have your power steering system checked by a mechanic.

Does the noise occur only when the vehicle is moving?

Try moving the steering wheel from side to side, while stationary (but don't do it too often, or you might damage something). If the noise is still present when the car is stationary, then it probably is the power steering system.

If the noise only occurs while the vehicle is moving, it could be a problem with the differential/final drive, or even wheel bearings.

    The fumes that you smell could be due to a small amount of power steering fluid leaking onto a hot component, such as the exhaust.

    Although the fluid level may appear to be okay, it is still possible that there is a fault with the hydraulic system.

    A large enough build up of transmission/power steering fluid can cause a fire.

    You should go and have your car examined by a mechanic.

Makes a loud steering noise in rear of car when makes a sharp hard turn to the left, what could this be?


Sounds like a right wheel bearing. You should be able to jack up the right side and do one of two things. Shake the wheel and see if the bearing is sloppy or rotate the wheel by habd and see if you can hear the bearing making noise. They are pretty common on these vehicles.

Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

Noise coming from the front end of my 2003 dodge durango


You didn't specify if your vehicle is 2- or 4-wheel drive. If 4 wheel, you may have a failing contstant velocity joint which, when having developed worn spots in the cage can cause the noise you describe.
Typically, turning the wheel back and forth can cause the noise to become less or more loud and often the combination of a specific speed and driving a certain curve radius can cause the noise to nearly disappear or become more pronounced.

Very loud "rubbing " sound when driving only


you did damage to the wheel bearing i bet it sounds like a airplane sound. also if you steering wheel is off 7"then have front end aligned because this will destroy the tires and they will make noise.

2003 BMW 325I Power Steering


when looking at the engine with the hood up, look to the right hand side for something that looks like this (#1 in the pic): http://www.realoem.com/bmw/showparts.do?model=ET37&mospid=47720&btnr=32_0957&hg=32&fg=20

it will be black in color, but don't confuse it with the oil filter housing. power steering reservoir will have a unique cap (#2 in the pic) that can be removed with your hand. the one that has the large nut on top is the oil filter. remove the cap and put in the correct fluid.

hope this helped.

Make sure you check your power steering fluid... if it's even low, it will make a terrible noise...run it on empty too long and your can ruin your power steering pump.
