Power Steering and RPM

Hi all,

Just want to start off saying Hi. I'm a new Mini owner (2003 MC, non S). We bought it with 78k on the odo.

After reading some horrifying stories about the PS pump, I contacted the previous owner. He promptly sent me the receipt that shows he changed the PS pump at around 76k mile about 1 month ago.

Is it safe to assume I have the new pump and the problem won't happen?

Also, I notice that when idle and I turn the steering wheel, my RPM would drop about 50 to 100 rpm then back up as I stop turning the wheel. Is this normal?

Thank you,

Phantom

BTW, the marketplace is great. Bought a few interior pieces from the members and they have shipped them very promptly. Better than eBay!!!

Its normal for the RPM to drop in idle when turning the wheel. The reason being that turning the wheel put more load on the pump motor, putting more load on the alternator, putting more load on the engine. It takes the motor a moment to compensate for that so that is why you see an rpm drop.

"After reading some horrifying stories about the PS pump" - it's actually the PS fan that's an issue. The first gen would stop, overheat &, in some cases, cause a fire.

Thanks guys.

On the invoice, it said the previous owner replaced the PS pump.

I have an 03 "S". The PS fan was replaced in 05. My guess is your PS fan was replaced at some point.
