Me again - doesn't any body else work on the weekends? 
So this weekend was spent giving attention to the MINI which finally succumbed to the dreaded power steering pump failure at 190k. A new one is about 12kR part only, so after some internet research it appeared as though there might be a chance to repair it. A totally enclosed electric motor drives the pump. It sits under the exhaust and is prone to overheating and failure in many ways, one of which is because it is enclosed all the brush debris stay inside and cause shorts and get between the 4 brushes and commutator. So I thought would give it a checkout. It's really a pain to remove like everything else, and if you thought working on a Mini was space challenged the MINI is 10 times worse! Anyway removed about 3 tablespoons of dust from the motor, excluding the lot that got blown away with compressed air (not an exaggeration!) The pump section was fine and at least it working again........ for now
