Hi Guys,
You may remember I posted about a leak I was having in my boot well last year: http://www.z4-forum.com/forum/viewtopic.php?f=45&t=61309 (sorry for not posting an update).
After extensive drying the motor worked again, I wasn't able to trace where the water was getting in, but it seemed to stop coming in in such huge quantities.
After keeping an eye on it for many months all seemed fine, until the nice weather reappeared over the last few weeks and I tried the roof; the water was back with a vengeance, and has completely corroded the connections to the wiring harness (fell apart in my hands), and possibly the pump itself.
As it was in for a service today, I asked them to take a look at it to see what work would be needed, and was quoted £2700 for a new wiring harness (£20 on ebay), pump (used £250 ebay), relays and fuses (pennies - although I've tested both relays and they work fine, fuses ok too). Obviously there is labour, expertise and a degree of security in the cost, but I just can't justify spending that sum on what should be a straightforward swapout - which brings me to my question:
My intention is to replace the wiring harness, see if the pump works, and if not replace the pump. Is this a straightforward job? Does anyone have any guidance? My main concern would be refilling the pump properly with hydraulic fluid afterwards (I'm pretty handy but not done much with hydraulic systems before).
