Power Steering BMW Mini One 2003

The power steering is very stiff now, could it be the pump itself or just a loose electrical connection. How can I determine what could the fault be?
Thank you, cheers for now.

    The steering wheel was hard to turn so I replaced the blown fuse and tried again. The steering was still hard but better. Any recommendations.

    My power steering is also stiff, began early this week, though I just changed the pump about 1500 miles ago. About a month ago, the car overheated once and then again when I had the air conditioning on. When I just checked the power steering fluid today, I realized my radiator fan is not working. Could it be a 05 fuse? If so, what would cause that fuse to blow and would my new pump now be ruined if its fan also was not working, since they both are connected to the same fuse?

Is the fluid level full? a common problem with these pumps is leakage. Check the pump the rack and all the hoses for any leaks as a first priority. another cause could be the wheel alignment.

Hope you find the problem

My mini cooper has recently been undergoing problems with the power steering (common problem) so I had the power steering pump replaced just last week. The steering is still becoming stiff??? What else...


sounds like your car could be possessed.
or
it may be a dead battery? in car or fob.
if you are positive the replacement pump is good and you have enough fluid and no air in system.
then it may be the steering linkage (a rusty stiff joint) will do that.
has the car ever been in an accident?

After replacing power steering pump, steering still feels hard. rack and pinion was replaced less than 3k miles. car has been sitting for several months.


i've had a similar issue with a 99 M3. really stiff steering. i thought i was getting old and weak.

I was chasing another problem when i discovered a solution for my stiff steering issue.

Most of these vehicles have a valve that helps control steering pump fluid flow at various speeds.

i.e at higher speed you want stiffer steering. at low speeds easier steering. however, how does the pump known your going faster?

Note: all bmw steering hoses leak...

As your car ages, so do electrical contacts, especially in harser climates.

I used eletrical contact cleaner and di-electric grease to solve an intermittemt ASC problem.

This also cleared up the steering issue.

get some electrical contact cleaner and some di-electric grease. pop your hood and clean as many electrical connections as you can and apply a little di-electric grease after the contact cleaner drys.
even do the dme.

Note: I have replaced the power steering rack twice before i discovered this fix. You may also fix some other issues in the meantime.

electrical contacts may be the biggest problem source for most newer vehocles since they tie everything together.

Power steering does not work


pretty vague. do you mean it's stiff at low speeds?

these cars stiffen the steering by reducing fluid flow via a valve in the steering pump. if the signal identifying speed is hampered, then the pumop may think you are at high speeds all the time.

electrical contacts are the most common source for most car problems these days.

use electrical contact cleaner followed by di-electric grease on as many electrical connection in the car as possible, including the dme.

spray the contacts, let dry, apply a small amount of di-electric grease and then refit the connection. under the hood connections will be the ones that need immediate attention.

Power steering keeps going stiff all the time


There are 2 things that cause power steering to go stiff. The power steering pump itself either from failure or "lack of fluid" and the rack and pinion assy under the car.
Most of the time the failure is the power steering pump itself. The teflon rollers fail inside the pump and it either stops providing an output pressure or it seizes up. You can loosen the power steering pump belt then try to rotate the pump by hand. It should move by hand. If it feels like it is intermittently locking up as you rotate, it the teflon rollers have failed and the pump will need to be replaced.

Thanks for using FixYa.

Power steering


bad electrical signal to the pump. pumps thinks its going fast. the valve that controls the fluid flow to make steeering stiffer at higher speeds is confused.

use electrical contact cleaner and d-electric grease to fix contact problems.
pop the hood and cleans as many connections as possible, let dry and apply a small amount of di-electric grease to those connections, then re-connect the plugs. even do the dme connections to the main wiring harness.

this will solve many electrical contact problems seen in older cars.

Power steering stiff - is it the pump ? or the steering rack?


If the wheel binds up or you encounter harder steering in one direction but not the other, it's your rack. Check for leaks, is it from the connecting hose or the rack itself. Can't find it? It's usually on the bottom rear of your engine,a tie rod on either side will attach to your steering knuckle. If your steering is stiff while wheel is centered or at maximum lock it's your pump.

Never worked on a mini in particular. Doing a quick google search and pumps (minus labour) seem to be 350-450$ depending where you go, unless there's some crazy book time i'm unaware of, 1300$ seems pretty steep.

Is there a noise when you turn? If there is, jack up the front end and remove the cap off your power steering resevoir. Slowly turn the wheel from lock to lock, while the engine is running, to bleed any air out of the system
If you replace one or the other, don't forget to do the above step.

A constant whizzing


that whining noise is definately your power steering pump. the earlier models eg 2001-2003 just have noisy ones. so they say, if that noise become really excessive; its an early warning that its gonna fail. the newer pumps are much quiter, but i was quoted approx 1200+ CND for a new pump. I have a 2003 cooper, and the whining noise is loud. only once has the steering been really stiff, but i resolve that problem by restarting the vehicle. watch out tho, the power sttering could fail on you while your driving around a corner, and if you dont have both hands on the wheel, you'll go strait.

Power steering


MOST LIKELY THIS IS THE POWER STEERING PUMP AND THE ELECTRIC ASSIST FAN UNIT CONNECTED TO IT. OFTEN THE FAN COVER WILL OR CAN GET CLOGGED, BUT MORE LIKELY IT IS THE PUMP. IF IT GOES OUT IT USUALLY DO SO SLOWLY. THE STEERING WILL BE HARDER BUT YOU WILL BE ABLE TO STEER. THE NORMAL COST FOR THE REPAIR IS $1000 WITH LABOR. IT DOES NOT TAKE LONG, BUT CONSIDER BUYING THE PART ONLINE AND DOING IT YOURSELF OR TAKE THE PART TO A COMPETENT GARAGE
AND HAVE THEM DO IT.YOU COULD SAFE HALF THE COST!
REALLY.
