Aren't the OEM arms both 22"?
IIRC my aftermarket "aero" blades are 24" (driver) and 23".

I can't check the numbers for you Jim, but at that price you had to buy the whole assembaly (with aerofoil), now you have the OEM blades next time you need to change them you can replace just the rubbers at around £8

In this photo you can see one of the metal strips that hold the rubber in place, (there is one each side), you remove these and side rubber out as in second photo.

The OEM ones definitely feature a shorter blade on the passenger side Jim, and also the curve is different on each blade too

Any idea how I can get hold of the correct part numbers to launch a dispute?

If ordered separately: 4B0 955 425 + 4A0 955 425 B

2 wiper blades in one kit: 4B0 998 003

One rubber: 895 955 429 A


Interestingly, the same wiper blades are used on A6 C5 and A8 D2.

Mine say that's what they are:
S 4BO 955 425 (with aerofoil or whatever it's called)
4AO 955 425B

But I'm pretty sure they're the same length....off to check before it gets dark

They are the same length (550mm). Hence the same rubber part for right and left.

Just measured my blades (probably non-OEM - they have no writing on them apart from "2Edge") and they are both 22inches (559mm). Both look the same and both are very curved.

mine are both 22in, (£4.99 Aldi specials), been on for two years worked great and just beginning to think they might need replaced soon+++

heres the post when Oli did his -

I haven't gone and measured mine Jim so might be my mistake - sounds like they are the same length after what others have written/checked, but one is definitely "more curved" but you'd better not launch an "eBay prosecution" just yet! :rolleyes:
