Hello, thank you for writing in. The vehicle may need a series of tests at this point. With no diagnostic codes to assist us in diagnostics, the power steering system components will need to be tested individually. When you refer to the steering continuously turning, what do you mean by that? If the power steering pump is making a "whirling" or "buzzing" sound, it likely needs to be replaced. Check the power steering fluid level and color. Make sure it is not black or gritty. If it is low, there may be a leak which would explain the burning smell. The fluid would likely leak out of a hose, the pump, or the housing. Locating the leak would be top priority at that point. For more help diagnosing the power steering system, contact our service department.

Leaking vehicle fluid, cracked or blocked hoses, broken and malfunctioning pumps, and fluid contaminations are a few of the possible causes of steering wheel failure in your Mercedes. Other causes include worn power steering belts, lack of power steering fluid, or even oil leaks.
The light warns you that the power steering system has failed and prompts you to investigate for a cause. The cause may vary according to the type of power steering system in your car. In hydraulic power steering systems, a leak in the system causing a low fluid level is the most common cause for this problem.
Improper Fluid Levels
Too much and your valves and seals could collapse under the pressure. Not enough and the fluid can`t exert the force needed to turn your car. Replacing your fluid on time will help prevent this issue, but any leaks can cause a loss of fluid that will ultimately lead to power steering failure.
Vehicles that are designed with a power steering pump should only be used when the power steering is operational. When the power steering stops working, you should refrain from operating the vehicle until the pump is replaced.
All you need to do is turn off your engine, then restart it so the light can reset. In most cases, it should come back on, and this only indicates that it may have thought it suspected a problem due to a mistake in the computer system.
Electronic failure is when the electrical systems keeping the power steering running stop functioning. This type of failure can be caused by a fuse issue, so you can easily check the fuse box to see if one of the fuses needs replacing.
Today`s electronic power steering systems may fail due to issues with the mounted electric motor. In particular, excessive heat on the motor is likely to cause the failure modes. Infiltration of the system environment by water, dirt, or other contaminants will also likely lead to EPS failure.
M-type fuse.
The steering angle sensor (SAS) determines where the driver wants to steer, matching the steering wheel with the vehicle`s wheels. Located within the steering column, the steering angle sensor always has more than one sensor packaged together in a single unit for redundancy, accuracy, and diagnostics.
Vehicles that are designed with a power steering pump should only be used when the power steering is operational. When the power steering stops working, you should refrain from operating the vehicle until the pump is replaced.
This problem can be fixed on your own, but if you`re not sure how to fix electric power steering problems, take it to a certified mechanic.
In most cases, this is usually caused by a lack of power steering fluid or a leak in the system. It could also mean that you have a worn-out power steering pump that needs replacing.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

had power steering pump replaced but power steering fluid is leaking
ANSWER : This suggests that you may have a leak somewhere else in your power steering system such as one of the hoses or the rack and pinion system. As you may know, the power steering system is a highly pressurized system that can have as much as 300+psi of pressure in the system at times, so it is not uncommon for these types of leaks to happen. If you’d like to get this fixed, I would recommend having an expert from YourMechanic come to your location to diagnose the leak in your power steering system and make the the necessary repairs to fix it.

Chrysler 3.8 L. T&C power steering rack and pump replacement.
ANSWER : As you may know, the power steering rack pumps power steering fluid through a series of small reed valves that help to produce hydraulic pressure as the system is pressurized by the pump. This is what allows the power steering system to assist you in steering your car. When either the pump or the rack is not working properly, one or the other can sometimes over compensate for the other to a certain degree, but will eventually be overworked and fail. It sounds like this may have been the case in your situation. I would suggest having a second opinion on the previous mechanic’s work. If you’d like a professional from YourMechanic can come to your home or place of business to properly diagnose and repair your power steering system.
