Product description
If your front wipers are starting to smear, skip, or leave streaks, a fresh pair can make the difference between “barely okay” and clear visibility in everyday rain and drizzle. The Bosch Aerotwin A 930 S is a set of two replacement blades designed for the front windscreen, supplied with a pre-assembled adapter.
That said, it’s not a universal fit. This specific Aerotwin set is stated as only for left-hand drive (EU), so compatibility is a big part of the decision here.
The essentials
Bosch’s Aerotwin A 930 S set is built to replace worn front wiper blades with two different lengths (600mm and 475mm). It’s meant for drivers who want a straightforward blade swap rather than experimenting with mismatched sizes.
On paper, the appeal is simple: two blades, pre-assembled adapter included, and a Bosch part number reference (OE: A1768202700 / 1768202700) to help line things up with the right replacement.
What stands out in use
What you’ll notice day to day is the basic job done properly: when the blades are correct for your car’s wiper arm and screen, they can clear a wider, more even swathe instead of hopping around or streaking at speed. Aerotwin blades are generally chosen by people who want dependable, routine clearing without getting overly technical.
A small practical example: if you’re commuting in the UK and the windscreen looks fine when stationary but starts to smear when you hit motorway pace, the problem is often the blade condition and fit. Replacing both front blades together is usually the sensible move rather than changing just one side and hoping the other keeps up.
Compatibility matters (and this one has a clear limit)
Bosch lists a vehicle compatibility set that includes models such as BMW 3 Touring (E91), BMW 3 Touring (F31), BMW 3 Sedan (E90, F30, F80), BMW 3 Gran Turismo (F34), Audi A3 Sportback (8PA) and Audi A3 Hatchback (8P1), plus Mercedes-Benz A-Class (W176).
However, the product is also explicitly marked as “Only for left-hand drive (EU)”. So it’s not just about the car make and model—drive configuration matters. It’s worth checking on the vehicle selector (as Bosch/retail listings suggest) rather than relying purely on the OE number.

It may not suit you if…
It may not be a great match if your car is right-hand drive, because this listing is specific to left-hand drive (EU). Also, if your wiper system already uses a different blade setup, you could end up with a fitment mismatch even if the car model sounds correct on first glance.
Buying verdict
It makes sense to buy the Bosch Aerotwin A 930 S if you want a straight replacement for front wipers, you’re dealing with typical rain visibility issues, and the vehicle selector confirms the fit for your exact car (including the left-hand drive condition).
You may want to skip it if you’re right-hand drive, you can’t confirm the adapter/blade type matches your wiper arms, or you’re only replacing one blade and expecting it to “balance out” poor clearing from the other side.
Mini FAQ
How do I make sure this fits my car?
Use the vehicle selector on the listing and also cross-check the OE number provided (A1768202700 / 1768202700). Don’t rely only on model name.
Why does it mention left-hand drive (EU)?
Because blade compatibility can depend on the overall wiper arrangement used in different markets. This set is specifically stated for left-hand drive (EU).
Is it better to replace both front blades at once?
In most day-to-day situations, replacing both together is the more consistent approach—one fresh blade can look fine while the older one still causes uneven clearing.
What sizes are included in the set?
The set is supplied as two blades with sizes 600mm and 475mm.
What should I look for if wipers are still streaky after fitting?
If it’s still not right after installation, it usually points to a fitment mismatch or incorrect adapter/arm compatibility—so it’s worth re-checking the fit against the vehicle selector.
