Hello everyone, firstly I would like to say thank you to everyone who takes the time to post information about fixes they have completed on their Minis, very useful for the rest of us. They are a fun car, but the more I work on the Mini, the more I realise what a pain this car will be to maintain as it gets older!
Recently my wife's 2005 Mini Convertible started intermittantly losing the power steering, after scrolling through various posts in this forum I found some very useful information on how to remove the EHPS pump and give the electronics a clean, which hopefully will prolong the pump's life. As a replacement pump on ebay would have set us back $500 AUD, still better than paying the Perth Mini Garage $1300 AUD just for the pump! Oh and they wanted $500 AUD for the cooling fan!!!
I noticed in some of the posts that I read, some people were asking about an alternative to the Pentosin power steering fluid only available from the Mini dealer (at least here in Perth, Western Australia) well for Australian residents Penrite make one called LDAS, if you check the Penrite website it lists the stockists where it can be purchased, it is a dollar dearer than the Mini Garage supplied fluid, but if you do not live near a dealer, then you have an alternative. I also asked the Perth Mini Garage about their "Goodwill Policy" and it does not cover the known EHPS failure problem.
The Mini Garage mentioned that failure of the EHPS cooling fan is generally the cause of the EHPS pump problem, which does not seem to be entirely true, but it is worth checking when changing the oil. With that in mind according to the Bentley workshop manual the EHPS cooling fan works in conjunction with the engine cooling fan. So if you are checking to see if the fan is working wait until the engine cooling fan starts before checking the EHPS cooling fan, best to put your hand in front of the fan, as it is difficult to see it runnning with the car on the ground.
Once again a big thank you to this website and all those who contribute to it.
