The Audi Avant Twin Rotating Washer Jet & Solid Rear Wiper Mod

[xbiker423]

Cool! Post pics for us!
Some of the Audi SUVs have solid rear wiper arms, but in the UK thread they say that the top (or sweep) of the wiper is too high. I'm not sure if that was due to a GTI upper fairing (wing) above the rear window, or that the wiper arm was just too long.
I bought my original solid wiper arm from ebay. When it finally arrived (2nd attempt), it compared very well with the OE Audi unit. It was listed as aftermarket from Eastern Europe, but it must be a Skoda or Audi item, as it's exactly the same. I'd say the fit and finish are 100% as good.
xbiker- how close are you to the Long Trail brewpub? Love LT!

Good to know about the eBay arms. I just placed my order with ECS for the Q5 wiper so hopefully I'll have this done by next weekend. One more project I can cross off my list. I'm ok with reports of the Q5 arm being possibly too long. I have a wagon so it should fit. I'll go out and measure now that I have details (thanks to Graeme!).
I'm only about half an hour from Long Trail. Oddly, I've never gone.

Great thread!
If you also want an aero rear wiper and rotating jet you can use the Q5 aero arm and blade with the same Audi motor.

8E9 955 711 E Motor
8K9 955 985 A Jet
8K9 955 205 Cap
8R0 955 407 1P9 Q5 Aero Arm
8R0 955 425 Q5 Aero Blade

Graeme -
Thanks for posting these #s here. I got them from a ukmkivs.net thread and was going to post them here. Now I don't have to!
As previously stated - awesome site. I did the cruise LED mod (and have gotten many, many ideas) thanks to you.

Disconnect the fluid line. This is usually done with a small flat blade screwdriver, but most will just pull off.

I would just add that to release this clip, you rotate the black C-clip piece 90 degrees around the grey end and the whole connection goes loose and pulls straight apart.

You can see the grey piece has a flat on each side - line the gap in the black C-clip up with the flat to release the tension on the pipe fitting.

To reinstall - rotate the C-clip back to its original position and push hose onto connector and you will hear a click when its fully home.

Subscribed. Probably gonna do this on the Passat & Jetta

Thanks Graeme! I'll try to edit the text and update to add your instructions.

Just completed this on an 03 Golf wagon. Apart from the plastic cover piece being slightly larger than on the regular golf, everything is the same. Thanks for the great guide... Looking forward to some dirty glass!

 

[graeme86]

I have now installed the Audi rear wiper motor and tried some different wiper arms to get the best fit on the Golf glass.

My Webspace page also has a full comparison of the different OEM blades that fit.

 

[Lex4TDI4Life]

Wow! Gonna have to hit the scrap yard for some wrecked Q5s

 

[smopoim86]

Bought parts tonight. I thought I was done with the modding.

 

[SFHGolfTDI]

Finally got the dreaded leak from my wiper motor shaft. The fixes are either too expensive, or too time consuming. So I'm leaning toward this tasteful mod.

Anyone know if Audi wiper motor part 8L0 955 711 B is the same as 8E9 955 711 E? I'm looking at an alright deal on one from a 2001 Allroad, but I can't tell if it has the twin washer, will work with the Q5 wiper arm, etc. Anyone know?

 

[graeme86]

I believe you may find that this wiper motor parks the wiper on the left side of the glass and it also has the VW style jet.

 

[SFHGolfTDI]

Is 8R0 955 711 B the same as 8E9 955 711 E?

If anyone has a lead on where I can find these parts on the cheap, that would be great. eBay isn't turning up too many of the right wiper motors at the moment.

EDIT: At least according to this, here are all the part numbers that refer to the same motor as 8E9 955 711 E: 8E9955711E ; 8E9-955-711-A; 8E9-955-711-B; 8E9-955-711-C; 8E9-955-711-D; 8E9955711; 8E9955711A; 8E9955711B; 8E9955711C; 8E9955711D; 8R0955711A

I don't know why 8R0955711B isn't on that list and if there is any substantive difference between the two, but I suspect not.

 

[graeme86]

Looking at google images, the 8R0955711B does look physically identical to the 8E9955711E in respect of the shape of mounting legs, even the electrical plug is the same.

But if it was given a new part number then there is some technical difference...perhaps they changed the intermittent sweep time or the internal gearing to slow/speed up the arm sweep..I don't know the actual reason.

All the other parts quoted above for arm and jet etc are still the same with this 8R0955711B motor.

Your call.

Edit:

Found this video of a Q5 rear wiper in action:

https://www.youtube.com/watch?v=D0sGpzt1sFg

This would have the later 8R0955711B motor.

Clearly the intermittent sweep is only about 4 seconds delay in this video.

On my installation with the 8E9955711E motor, the sweep delay is appreciably longer - about 8 seconds, so I would say they have certainly reduced the intermittent sweep time with this later motor, hence the new number allocated.

[SFHGolfTDI]

Is it worth trying to get the connector that attaches to the washer port on the motor? I think its 1J0955875P from what I can tell. Mine is black with no sleeve and looks different from what you both have pictured (I have the Bosch wiper motor, not valeo). I'm worried my connector might not fit right.

But they seem very securely attached to the wiper hose. How do those come off? Hot water?

 

[SFHGolfTDI]

Oh well. I just fixed my old sprayer tube with some new stainless steel tubing and JB Weld. I couldn't justify $100+ for this nifty mod when I could fix for $12 and put the money toward an RC3 or nozzles later. If a $50 motor/wiper comes up on eBay, I'll consider jumping on it. But Audi parts are $$ I'm discovering.

 

[SFHGolfTDI]

Finally got my hands on a motor for $40 on eBay.

Graeme, or anyone, seems that the new A4 Avants also use an aero wiper similar to the Q5. But the part numbers are different for both the arm and the blade, and I can't figure out what the size differences are. I'm trying to get comparative measurements for the A4 vs. Q5 wiper arms as it seems they are not the same part, but might be another possible replacement with the right blade combination:

8K99554071P9 - B8 A4 Avant/Allroad wiper arm
8K9955425 - Blade (a long 400mm from what I've been able to tell).

 

[graeme86]

My information is that blade is 413mm long by itself.

I dont have the overall sweep measurement (center of pivot to tip of installed blade).

Do what I did - go down to Audi showroom with a tape measure

Haha. I might have to do that.

 

[graeme86]

Be prepared for lots of strange looks.

 

[SFHGolfTDI]

FYI, I did a little more research and the Q5 and latest Touareg 7P use the same wiper arm and cap, but the Touareg uses the longer 360mm arm. I think this provides the best fit based on Graeme's research for the MK4 Golf and my measurements on my existing setup. This is especially helpful if you are looking for a complete setup on eBay (either aftermarket or used), without having to mix and match parts.

7P6 955 427 Wiper Blade
8K9 955 205 Cap
8R0 955 407 1P9 Q5 Wiper Arm

 

[SFHGolfTDI]

Got some answers back from an Avant owner on Vortex about the length of the wiper. I measured the rear window on the Golf and that it is way too long for the VW Golf MK4, not sure about fitment with smaller blades (would need to take off about 1.5" of the total length, so a 13"/330mm blade instead of 16") or on a Jetta Wagon. The arm is probably an inch or so longer than the Q5/Touareg arm as well. Seems the Touareg/Q5 setup is the way to go with Touareg blades:

I just measured the one on our 2014 allroad.
Total Arm length from mounting point to tip of blade (your longer distance) is 19 3/4"
arm just itself length (your shorter distance) is 12 1/2"
blade length is 16"

http://forums.vwvortex.com/showthre...with-B8-Avant-A4-take-this-measurement-for-me

 

[graeme86]

Interesting. thanks - will add measurements to my data base.

I can tell you that the Q5 blade 8R0 955 425 is 330 mm

The A1 Sportback arm 8X4 955 425 is 320mm long, so slightly shorter again.

Depends on the look you want..long arm and stubby blade or whatever.

But the better combination for maximum cleaning area is a shorter arm with the longest blade, especially sweeping the area near the pivot point.

 

[SFHGolfTDI]

Agreed. That's what I'm going for. Motor delivered. Waiting on used Touareg wiper arm and blade from German eBay. Still not as cheap as I was hoping overall, but I hope to recoup some costs by selling my current aero wiper setup.

Shady! Sorry I missed your posts. This thread wasn't popping up in my CP subscribed after an extended fall absence (?).

Luckily, we have Graeme to pick up my slack!

Also, I can edit the parts list above, if you guys can help me narrow down the ones we have confirmed as compatible. And I finally edited the instructions to include Graeme's notes and helpers.

And Graeme, if you see this, I finally got the switch and relay from UK ebay to add a rear fog light switch to my kick panel. I'll send you an email once the weather here improves!

 

[SFHGolfTDI]

I was wondering why you were ignoring me, Steve! This how-to has been awesome by the way. Very well done.

I think in the US market these parts already previously referenced in the original posts and this thread provide the best fit for the Golf (we don't have the longest blade available that Graeme referenced):

7P6955427 Touareg Wiper Blade
8R09554071P9 Touareg/Q5 Wiper Arm
8K9955205 Cap

The A4/Avant wiper arm that I was wondering about (8K99554071P9) is in my opinion too long but can be made to work with shorter blades, but that gives you less wiping area and a "stubby" look. Not sure about fit on MK4 Jetta Wagons though. I don't know how the rear window sizes differ.

S- Sorry! I've started adding threads back into my CP. Most of them are still subscribed. Maybe they just drop out after a while if I don't post? Not sure.

Glad the thread helped- at least as a basis for everyone else to add info and tips.

I'll add your info above to the post on part numbers- thanks!

 

[SFHGolfTDI]

Wow, that was frustrating. I excitedly went to install everything today. Got it all buckled together and tested it. Sprayed awesome. Went to look at the backside of the motor and it was dripping washer fluid and had an internal leak just like the VW ones have! (I attempted to open it, but it seems it is not repairable in the same way and I didn't want to break it since I've requested a return from the eBay seller and reinstalled my old repaired wiper motor. Very anticlimactic. I now have a Touareg rear wiper arm/blade from Germany, but no motor. I'll hold on to it and see if any wiper motor turns up on eBay or Car-Part at a decent price, though this one was hard to beat at $40. But I'm now pretty leery of having the same issue with other used motors.

Moral of the story: 1) Beware with used wiper motors (this was a 2009, so I was hoping it had some life in it still); 2) this model Valeo motor is prone to a similar problem as the OE one on our MK4s.

 

[hskrdu]

S- that stinks! Sorry to hear it. I'll keep my eyes out for an Audi motor for you. Last salvage yard I went to had 4 (!) Audi avants, but every washer motor was gone. I'm really curious as to why it is leaking. I haven't opened my A3 motor up, just the OE Golf motor- and we all know what the problem is with that series. I did see some complaints on the UK forums, but it didn't seem to be as widespread as the VW rusty fluid pipe issue- maybe that's only b/c fewer Audis are sold.

Obviously the diameter of the fluid pipe on the VW doesn't fit the Audi twin jet, but could we repair the VW pipe in such a way to make it fit the Audi jet, instead of just a repair to fit the original VW jet?

My OE Golf motor is set aside with ss piping ready to go, so maybe I'll see if I can figure something out. This would provide a long term solution, and lower the cost.

 

[SFHGolfTDI]

I've been doing a little bit of research this morning; the seller offered me 3/4 refund and I keep the motor, so I'll just try to repair it. Unlike the brass pipe that is the failure point in the OE MK4 units, these Audi Valeo motors have a weak point where the rotating outer pipe meets the plastic fitting on the back side of the motor (by the gears). There is either an o-ring that goes bad (?), or whatever method they use to seal between the plastic and the rotating tube piece fails. The only repairs I've seen people using is plumbers tape around the metal portion to reseal it; this doesn't sound very satisfactory to me for a moving part. Here are a few repair threads:

http://www.vwaudiforum.co.uk/forum/...-C6-)-Rear-wiper-motor-removal-refurb-install (may require registration)
http://www.matthewvaras.com/2014/03/14/2007-audi-a6-avant-rear-wiper-motor-repair/ (didn't seem to address the leak which was obviously there; just cleaned and regreased motor and sealed it back up)
http://uk-audis.net/topic/3428-rear-wiper-motor-leaking-water-from-casing/#entry37141

I'll try to crack my motor open sometime soon to see what is going on in there. Hopefully there is an easily replaceable o-ring or something similar to seal it up again. In the meantime, worth keeping an eye on your motors as it seems there is no escaping rear wiper issues in the VAG family!

 

[graeme86]

Looks like the 8E9955711E version motor has now been superseded to a 8E9955711G version.

Don't know the exact internal technical details of the difference between old and new versions, but externally has same mounting tabs and correct shape electrical plug socket, so visually identical.

 

[SFHGolfTDI]

Looking at google images, the 8R0955711B does look physically identical to the 8E9955711E in respect of the shape of mounting legs, even the electrical plug is the same.

I recently picked up the 8R0955711B motor from a 2011 Audi Q5. I haven't had a chance to test it out yet to confirm fitment and that it will behave in the MK4 platform. Will update when I do.

Crossing my fingers that this one is not a leaker.
