R50/53 Power Steering?
It can be the power steering pump electrical motor. You can get it rebuilt for $200 at http://www.bba-reman.com/us/index.aspx.
My car just started doing this, too. I noticed that when I start out in the morning everything seems normal, but after about 45 minutes of driving it suddenly feels like I've got to manhandle the steering wheel. My drive to work is mostly in a straight line for about 45 miles while I'm on the expressway, so it's probably not that noticable then anyway. If it is just the electrical PS motor why is it intermittent? I'd think it would either work or not but not return to normal.
I'm replacing my pump in 02 cooper, but I could use some help with the removal. It looks so simple but I cant get to the bolts that are holding it in. Is there a special tool I need. Any feed back would be awesome.

Good luck!
I would also suggest you look at getting the OEM power steering fan duct kit....it will provide better airflow to your new ps pump, keeping it cooler and also protect/extend the life of you power steering fan. The duct is 80$ from moss.... I have one on my s, took 10 min to install.
Thanks!
I went to Mini of The Woodlands in Texas today. It turns out my P/S pump has an electrical fault and the fan is fine. No leaks - the fluid level was actually slightly above the max level.
Quote was $908.32 ($771.29 for the pump and $165 for labor).
Since it takes about an hour of driving to lose the P/S right now I'm going to hold off and see what happens. It's a disappointment that an '05 MCS with just shy of 80K miles needs a power steering pump. I've had other cars with nearly double the miles that never had this kind of problem. I've been driving for 34 years and never had one of these go bad.

I'm actually thinking about a proactive replacement at 75K. I've heard of others doing this and being amazed at the reclamation of performance they didn't realized they'd lost.
I don't like advising customers to run their MINI without the P/S pump working. Over the years we've seen several Engine bay fires and I worry that these fires are sometimes caused by the pump shorting out completely. Not trying to scare anyone, but I don't want to see a MINI die a firey death.
The newer style pumps like on the MINI , some BMWs and an ever increasing number of cars are an DC electric motor with brushes that wear out much like an generator/alternator....so now they have become a bit of a wear item, rather than a lifetime item like earlier pumps in exchange for the 1 to 2 % fuel savings these pumps are said to save when compared to the old beltdriven pumps that run all the time.
