ok, I just wanted to make sure my pump wasn't swapped out without my knowledge, i.e. taken from an R50 etc, as I've never had any service on the pump and expect that it's the original one that came with my car since I'm the original owner of my car.

At least for now I saved the $1450 on new pump, but still cost me under $1000 for the hoses and also was in for the annual oil change. I don't drive the car on a daily basis so to me it was not worth changing the pump at this time since it still works.


Thanks
It's been a few months now, what happened with the leak? did replacing just the hoses fix it?

still dry not leaking at all works just fine

Hi,


The hoses were all that were required, there may have been minor stains around where the mechanic was pointing to but it is not leaking or losing power steering fluid at all. I check it from time to time and it is still dry around the big circular clamp on the plastic housing.


Thanks for asking

just to make sure, were these the hoses you replaced?

hoses

They were the ones that lead into the pump from the reservoir

Power Steering Failure mini cooper S 2005

Guess I'll call the number posted above and report it.

My Mini Cooper S 2005 recently starting to have power steering problems. After driving for a period of time suddenly the power steering would fail and it would be "strong arm" steering. When the vehicle was turned off and then on again the power steering was back ( at least for a little while). I checked the fluid level ( no problem), I checked the fan ( no problem). I did a scan ( I have an Autel scanner), and it showed the 5529 code for the EHPS module, this apparently means " open or short circuit for the control circuit". So I detached the control circuit connector for the power steering pump ( this is the wire connector with the two small gage wires) that can be detached without even removing the fan ( although easier if you do). The connector was cleaned with connector cleaner and the filled with dielectric grease and reconnected. Interesting the locking mechanism for this connector is lousy........but a zip tie worked well so the connector is now together and solid.

Well at least for me the above fix worked and I have had no further problems. I do wonder if the connector is just in a lousy location and subject to aging. John

PS fan trigger ?

Hi,


I read in another thread that the PS fan only triggers when the radiator fan triggers on high speed stage 2, not when the AC is on and radiator fan is on low speed? someone said the PS fan is hard wired to run with the stage 2 radiator fan in high speed? I tried to test by turning on AC and did not see the PS fan spin, it is also the second PS fan on the car replaced under warranty years ago can't remember when exactly and I am also on my 2nd radiator fan which was replaced a couple years ago due to low speed resistor blown.


Thanks

For manual climate control, it only switches on when the radiator fan is on low, and ONLY if the DME deems it necessary to switch on. It make sense as traveling at high speed there is no need nor desirable for the fan to be running against much stronger air stream.

I only check the wiring diagram of late model R53 manual climate control. Auto climate control may be a bit different.

solved PS Fan does trigger with AC on

Hi, I did more research and came across another forum that suggested to check fuses, and I have found a blown fuse F41 as described here, when I changed the fuse and put in the new one, put the AC on and my PS fan turned on at the same time with stage 1 fan for radiator as well. I am suspicious of the dealer removing this fuse or not checking it when I had changed my ps pump hoses for leaking


http://www.psmini.org/forum/power-st...topic6701.html


Try checking fuse F05 and F08 in the fuse module next to the ECU. Also, fuse f 39 and f 41 in the kick panel.
There is also a power steering pump relay (k69923) in the kick panel.


This saved me a lot of grief. My PSF is working well and no noise at all.

Water Pump replaced. Next day issue with P/S

Is it time to get another car? I just had the Water Pump replaced (cost $878) and Check Engine Light still on. NEXT DAY, driving my Super S mini 2007 hatchback out of garage the power steering went out. VERY difficult to turn the wheel. Is this related to the fixing of the Water Pump? Happens when the car is cold, overnight in the garage). Had repeatable problem for two days then today no problem. Also noticed that following on the heels of this problem is a problem with a LOCKED steering wheel. This just started happening today. It does unlock but not before the icon for locked steering comes on. Total miles 150K. I'm getting the feeling that I should let this Mini just die. Sad!

Sounds like you are up against the argument between reliability and sentimentality. If this is your only means of transportation and you count on it to get to work, etc., you may be up against the reliability side of the equation. I have a 2002 MINI and as much as I like it, if I didn't have another means to get somewhere if I had to, I'd probably put it up for sale. You can rationalize some repairs, especially if you can do them yourself, as being close to/less than a car payment. But if you can't work on it yourself, and don't have a super mechanic who can fix what ails you, you probably need to find a more reliable set of wheels. 150K is not a bad number. But they are pricey to work on and with that many miles, there's no end to the things that will continue to dog you. I keep finding a puddle of coolant under my R53 - suspect it's something to do with the pressure cap. Old cars need drip pans...

Good luck!

Thank you Edgy, My sentiment completely. Trying one last effort to fix with my worthy mechanic. I will get a better idea after I see him, as to whether this is a continuing domino (one thing after the other) story. Sad, but might have to let it go...
