Clearing a Rear Wash Wipe Blockage.
in a BMW 1 series (E87) 116i ES (2006) 5 Door Hatchback...your part numbers may differ, check first
On thing that keeps cropping up on this forum, over the short while I've been here is the constant problem of a blockage in the rear wash wipe system.....Whilst this can be down to a number of things but usually its quite simple and is very easy to exchange part for part.
First and foremost I would like to thank the good people on this forum for providing me the knowledge on how to perform this task, without their help and guidance this thread would not have been possible.....Thank You!
Whilst my problem was a blockage somewhere, I knew that my motor was still working (so that was a relief)
Thinking then that it can be one of the following:
1) Nozzle Blockage
2) Pipeline Blockage
3) NRV Blockage (Non Return Valve)
So not being sure which of the above it could be I purchased all of the small parts necessary...to cover all bases as it were.
But this time I purchased a double nozzle (for more squirts for my buck)
Part number for Dbl Nozzle and Cover
The Parts supplied
The Double Nozzle
Halfrauds Finest Non Return Valve
Gunged up Single Nozzle before work began
Gently remove the cap lifting it upward to the right whilst gently pulling it back at the same time and it will slide out from under the washer arm.
Not looking too good....the nut was rusted so the nozzle would have been in from new and didn't look in the best or order.
Time for a change
Removing the old nozzle....
I found vice grips to be the best tool for this little job as you can really lock onto the nozzle head and not slip off as you may probably do with pliers.
With the grips firmly secured around the nozzle head...N.B. pull straight outward, don't twist or bend or you could risk breaking off part of the stem which in turn would turn a quite simple task into a big job.
Gently does it and out she comes.....
At this point I still wasnt sure which of the three faults were endemic to this situation so with the old nozzle out and the pipe (visible) I gave the pipe a good blow with an airline....I then went round to the steering column and flicked the rear washer on to see if there was a jet of water comming out of the pipe....To my relief...There was!.....So now I had eliminated the NRV and the Pipeline blockage scenarios in one motion.
So we were simply dealing with a nozzle fault (so glad I purchased the double one now )
Fitted and working (again )
The nozzle shank just pushes down into the tube (again gently does it) and the cap fits neatly over the unit as before.
Just before I fully located the cover....I lined up the nozzle with the hole in the plastic cover to make sure I was taking advantage of all the water available to the screen....I didn't want it hitting the cover, but going directly onto the rear screen....now it was just a question of fully locating the cover cap....Job Done....Estimated time ...1/2 hour.
Whilst I did not have to remove any of the boot panels to access the NRV (thankfully)...this was a job worth doing for low monetary outlay.
I hope it serves a purpose and helps folks with a similar problem and gives them the confidence to perform such an easy task themselves instead of fuelling the coffers of the Stealers.
Thank you for taking the time to read this small walkthrough
