I've had a leak in my Audi's PS fluid since I got it as a used car from my Grandparents. They just told me to replace the power steering fluid every week, and doing so has worked up until a few days ago. Now, the wheel is tight by the time I reach my destination regardless of how much I put in. I'm literally running through bottles of this stuff just to get to work. The leak is on the left side of the car, pretty far back (no where near the PS fluid reservoir). On top of this, when I check the fluid after arriving at my destination, I see bubbles in the fluid. Why is this happening now? How much do you think it will cost? Thanks guys.

Re: Power Steering Fluid Leak, boiling fluid.
Look at the steering rack on the side of the car that you think the leak is, look for the steering rack boot or gaiter, it looks like a black circular accordian type thing.
If this is bulging and leaking fluid the seal in the end of the rack is gone, this is one of the most common faults of leaking fluid and at the rate you are losing fluid, the leak is on the pressurised side of the system after the pump (the seal at the end of the rack)

Heavy steering (not caused by neglected low tyre pressures) is usually related to a problem or failure with the power steering pump system.
Items to check on the Power Steering (PS) System
1. Is the serpentine belt slipping on the power steering pump pulley because it is old and worn and needs to be replaced? If it is slipping it will likely be slipping on other pulleys also.
2. You have allowed the power steering fluid to run low and the PS pump is starved and is sucking air. Running the fluid low will damage the PS pump and the steering rack. Low fluid in the PS reservoir is normally a sign of a fluid leak in the system. A leak could be on a system hose, in the PS pump or in the steering rack.
3. The PS pump may have failed, hence cannot produce the required pressure in the PS system, and needs to be replaced.
These are real bad about having bad pumps, and bad leaking hoses. Make sure you still have good fluid and no leaks. Most likely it just drained again through a bad hose. If good fluid then pump is bad again. If your steering rack was bad it would be leaking real bad as well.
try to find exactly where it is leaking from, if it is from a seal in the power steering unit it would be wise to replace the whole unit, if it is in the hose leading to the unit you can have that replaced by a hydraulic hose doctor
they may have loosened the power steering pump to take off the belt and not put it back right.
They may have overtightened the belt which has worn the bearings out on the steering pump and made it start leaking from the bearings...
The power steering leak is creating bubbles in your power steering pump which gets strained more when turning, which causes it to be louder when turning. If you know where your leak is, then fix that, then try to bleed your ps system by filling up with the cap off the resevoir and turning the steering wheel max left to max left with trans fluid. if the noise is still there then your ps pump needs to be replaced along with the ps vsv located on the side of the pump.
Not really sure what your asking. But if your leaking from the power steering unit but it looks like tranny fluid it's because it is tranny fluid. Power steer fluid and tranny fluid are the same except that tranny fluid has a red dye in it.
try replacing the o ring or use double o rings between the reservoir and pump, pressure builds from use and the fluid blows out of this o ring even after the vehicle is off. When the dealer replaces the pump they re-use the reservoir and o ring so the problem does not get fixed. The fluid runs down the pump and the lines to the rack, instead of washing the engine and observing where the fluid is leaking from, they replace good parts until they find the problem. Sometimes one o ring isn't enough.
Check the fluid level and add as much as is appropriate. Keep in mind that you must use Audi/VW power steering fluid, as it's a proprietary mixture and use of "normal" fluid will ruin the steering rack (that'll run you over a grand to replace). Do this soon - extended periods of running with low PS fluid will burn up the pump.
