Car is making a whining noise that usually means low power steering fluid but level is fine. i am pretty sure the pump needs replaced but am not sure where exactly it is located in the engine compartment. If anyone knows anything about replacing the pump and the location any advice would be helpful-thank you
Before you replace the pump, check the filter located inside the oil tank. This filter cleans the oil before going to pump. REMEMBER that Audi uses a special oil!!! Not your normal power steering fluid! Mixing them could cause damage to the entire system!

I had a similar problem with my Lexus. There was no Power Steering fluid in the reservoir. It is located on the passenger side of the car under the hood by the firewall. Use ATF fluid, but make sure you get the right type. This is written on the lid and in the handbook. After filling, the noise went immediately.
Is it full of power steering fluid ? How are the hose's high pressure and low pressure ? Did you bleed the air out after changing the pump ? There is no filter .
Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid.
Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
Verify the fluid level. Repeat the bleed procedure, if necessary.
Check your transmission fluid level, as recommended in the Owner's Manual. Also, if your car is equipped with power steering, check the fluid level in the power steering reserve.
If all fluids are at recommended levels, see if you can locate the noise. If it is in the engine compartment, try to determine if the noise is coming from any of the serpentine belt pulleys.
Sometimes the bearings on air injector pumps fail in higher-mileage vehicles, first causing a "whining" noise, and ultimately resulting in the serpentine belt "chirping" or squealing on acceleration. Best you can do is make sure all fluids are at recommended levels, then try to pinpoint the source of the whining noise for further diagnosis.
you can hear your power steering pump working and if it's whining, it may be low on fluid.
Check the fluid level with the engine running and be very careful of moving or rotating parts.
Locate the pump and check the level (the cap will usually have a dipstick to measure the level attached to the cap and you read it the same way as your engine oil dipstick). DO NOT overfill the pump as it will just leak out and cause other issues.
If the level is very low, top it up then work the steering from side to side a few times then recheck the level. Careful, power steering fluid can get very hot!!
If the fluid in the pump looks dark or black, take the vehicle to your local mechanic and have the fluid replaced and the system flushed.
Do you hear noises while turning the wheel at low speeds or stationary? If you hear a whining noise check the power steering fluid level. A low fluid level would make a whining noise as well as cause stiff steering. If you hear a squealing noise check the power steering belt tension. A slipping belt would cause stiff steering also. If you hear no abnormal noises check to make sure the power steering belt is there. If all of the above check out ok you may have a bad power steering pump, steering gear or a blockage in a pressure line.
normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.
the power steering pump will also make a whining noise too.
turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).
if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.
if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.
oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
Checking the level of the power steering is a good start. The pump is mechanical, driven by the serpentine belt, and cannot be turned off. Your steering may seem normal but if you let it go, low fluid can destroy the pump.
