Leaking washer reservoir replaced pump

[TriX5]

Just got done with this job on the e70 and (after I exhausted all other options!!) I found the below useful instruction on a UK site. This job is not too bad but I was really missing an instruction with a clear picture of the fender bottom and the running board. I went the wrong way at first and dismantled a lot more than necessary. :-( It took me about 8 hours whereas with right instructions (and parts on hand) it can be done in an about an hour.....two at most.

Mine has OE running boards and I would add to the instruction below that I needed to first remove the RB to get to the bottom screws in the fender. The running board is held in place by a half dozen clips in the bottom and by a set of really tight clips in the door sill. Most of the clips in the bottom were missing and I broke the remaining three as well as four of the door sill clips, so get some spares before you start. It also has two tabs that are held in slots in the bottom of the fender.

I only cleared the front of the RB but it would probably be easier to release the back as well by taking 2 or 3 rivets out of the rear arch. Once the RB is free from the bottom of the fender it is time to release the torx bolts in the door hinge area. Once the RB is clear and the bottom of the fender can be moved away from the car you have space to get to the pumps. I took out a whole bunch more stuff but it is not necessary if you only need to exchange the pump. Mine had clear traces of washer fluid coming from the weep holes of the main pump. Also, no need to remove the front fender liner is you are not removing the reservoir, however then it is harder to see where the leak is.....

Here is the text from the UK site:
My 09 started leaking washer fluid little pools under the washer reservoir area on the Tarmac, also had a weak windscreen washer jet others were fine. What you need to do is replace the front and/or rear windscreen pumps, there is a mechanical seal which separates the pump from the electrics of the motor, when the seal goes fluid leaks out of a little tell tale, I thought it might just be the rubber filter grommets leaking, but the amount of chew to get to the job it's easier to replace it all while your in there. The reservoir and pumps are behind the drivers side (RH) front wing which needs partially removing to gain access to the pumps whilst leaving the reservoir in place. Get the drivers wheel off, remove 5 of the plastic rivets holding the wheel arch trim on these will need replacing with new, remove the inner wheel arch mudguard enough to see the washer reservoir and tie it forward. Use a torx bit to remove the screws securing the wing. There are 4 in the door hinge area, the others are on the bonnet shut, there is one Phillips screw under the windscreen trim where the windscreen meets the top of the wing. There are two 8mm screws securing the wing to the body from underneath down near the running board, the running board just pops off with a good heave with a long screw driver, again just pop it off enough to get access, then you can get at these 8mm screws. With those loose there will be just enough clearance to get your hand in to remove the pumps without fully removing the wing.

Below are a few pics. I had the reservoir more or less out because I wasn't sure what was leaking. The middle pump was the culprit. In the pic with the fender you can see where the 2 screws in bottom are and the tags on the RB that snap in to the bottom of the fender.

Next is the thermostat. It is on order and I am sure it will be just as much "fun" as this job.....
