HOW-TO: Mk3 Front & Rear Aero Wiper mod
« on: 29 April 2009, 20:01 »
VW Golf mk3 Front Wiper Mod

arm part numbers, you will need 1x of each of the following

8N2 955 407 D
6X2 955 409 C

o/s wiper is off a Lupo
n/s wiper is off a TT

Costs are approx £40 a wiper from VW

then you will need aero wipers to fit these and both wipers are 21" long



VW Golf mk3 Rear Wiper Mod

this mod changes the standard rear wiper from this:



to this:



to achieve this you will need

this: bmw 1 series rear wiper arm - p/n 61.62.7.138.507 £8.65 inc VAT



this: bmw 1 series rear wiper nut cover - p/n 61.62.7.199.566 £1.66 inc VAT
** this will need modifying before fitting - see later **



and this: bmw 1 series 11" rear wiper blade £11.20 inc VAT



if you don't know how to remove and refit the wiper arm there follows a very quick guide

lift off the nut cover



undo the bolt with either a 13mm wrench



or a 13mm socket wrench



lift off the arm

I cleaned the area thoroughly while the wiper was off



in true haynes style "refitting is a reversal of the removal"

nut cover modification


now... the brains among you will know that the BMW 1 series jet nozzle rotates with the wiper arm... (you mean you didn't know this!), whereas the majority of VW jet nozzles are fixed and therefore a larger space is cut in the nut cover.

the BMW nut cover will need to be modified otherwise you will only get about 1/10th of your screenwash on your screen, the rest will just hit the inside of your cover and run down your boot... not cool

to do this:



you will need this: dremel with various attachments



and this: an emery board from your mrs



** before you attack your nut cover note that the plastic is very soft and will mark easily **

I widened the nut cover hole already cut by BMW to the width required. it doesn't need to be as high as the BMW hole, however it looks stupid as a 'cross' so I widened the whole thing, you will need to do this to almost the two 'lines' that are inside the nut cover, take your time and then 'sand' off the plastic to make it nice and smooth, flat and level using the emery board.


11" wiper to 13" wiper mod


I found that the washer jet stream was hitting too high on the window and the wiper wasn't covering enough area to wipe all the water away, especially at the top.

** you will need your existing BMW 1 series rear wiper blade to complete this mod! **

go to halfords and buy a W100 13" Rear Flat Wiper Blade - ironically it is a VW golf MK5 rear wiper fit

you have to remove the adapter in the middle of the blade, I found the easiest way to do this was to remove the end cap on the blade keeping the rubber and metal strips aligned and then work my way down to the adapter in the middle by pulling the rubber out and twisting the metal strips... do this for both wipers and swap the clips over. Rebuild and re-clip the end caps on. Your 13" blade will now have a BMW fitting on it.

some pictures for your perusal:















If enough people are interested I will enquire about a group purchase of this... although the prices probably do not warrant enough discount to make this viable.

If you find that there is an easy or alternative way to do the nut cover modification then please post this as a reply with pictures.

thanks for reading

Guy

So for the 13" mod do you still need to purchase the BMW aero blade?

afaik yes... I wasn't able to figure out any other way of doing it, this included standing about for half an hour by the wipers in halfords scratching my heed  :rolleyes:
