rough idle, power steering pump?

I have a 95 BMW 540i, Anyhow went to start it up today and it was idling terribly, and when you turn the steering wheel the car wants to bog down and squeel extremely loud to were the neighbors are wandering what's going on lol it drives rough like it has no power I littlery had to stop at the end of my road it was si bad! Does it sound like my belts are going bad or my power steering pump? The car sounds like its missing, when you turn the wheel in both directions it will try to bog down and make a real bad squeeling sound! I mean the car sounds like complete sh$&26$!!! As you turn the wheel it feels like something is about to break! I need some help!

Any time you turn the wheel hard the power steering is pumping harder and therefore putting a load on the engine. So try this, instead of turning the wheel put the car in drive and keep your foot firmly on the brake. Hit the accelerator slowly while keeping your foot on the brake (this is putting a load on the engine as well) and see if it runs worse that way. If it does, you can suspect a coil and start inspecting them for cracks and testing to make sure they are firing. If not it may be something else. If you suspect a pulley may be frozen, with the car COLD remove the belts and start the car to see if it runs better (don't leave it running long without the belts on though because it will eventually overheat the engine and drain your battery)

I will try that thank you it just started doing it! I thought my power steering pump went out or my belts are worn out but the rough idle has got me confused I just don't understand I was running fine the last time I drove it.

It was running fine the last time drove it.. hahahaha story of my life..

i got my 540 with a bad pump.. o man it sucked.. wheel was heavy ya but it like sticks in places and you gotta be ready muscle it when it does..

i did not have surges at idle but i have a MT and would be giving throttle/clutch while turning at low speed and not notice maybe..


Good luck

Actually no, its a pain in the ass.. Or maybe thats your idea of fun..? hahahah jk

im guessing a 525 is much easier than a 540i/530i so maybe its not so bad.. i can tell you if you have a 540i check or just do that motor mount while you are there.. maybe this apply's to you also?

its a pain to get too for us

I found out today that my power steering pump is still good! I probably pinched a line were my grille came off and went under the car cause it happened rite after that. My friend said the lines were made of metal and I probably pinched one! Were are they located and could this be what happens?

Do the stomp test. Look in the stickies if you don't know what that is.

Yeah. Did you check the sticky at the top? It has a link to the stomp test procedure and it also has a video of a person doing it.

You should be able to turn your key to position 2 (dash lights on, but not cranking car) and the CEL should be on. If it is not, then the bulb is likely burned out. If that is the case, then you need to get the car to someone who has an OBD I code scanner to pull any error codes.

Until you either do the stomp test or have the codes read, you are kind of pissing in the wind in trying to diagnose the problem. Certainly not trying to be a jerk about it, but people here can speculate to the nth degree and still not know what the problem is. You need to get a diagnosis before you can treat the disease.

BTW, I don't think that your rough running engine is related to the belt squealing. I suppose it's possible, but unlikely. Once you get the engine running correctly, you can address the belt issue.

Good luck.

Yeah. He posted another thread correlating this to when his nose peice of his grill came off and he ran over it. O2 sensor was my though as well once he tied the two together.

BTW, good to hear from you again BMW FF. Where ya' been?

Re: rough idle, power steering pump?

The o2 is the first thing I thought about or the mass air flow sensor, I think that's what it is that screws into the intake
