BMW 3 Series Wiper Blade Size & Fitting Guide (2019-2024)
Wiper Blade Sizes
Front blade lengths and arm fitting for the BMW 3 Series, taken from the Bosch and Valeo entries in the TecDoc-derived parts catalogue. Catalogues publish a front set as two lengths and do not state which blade belongs on the driver’s arm of a right-hand-drive car, so this table labels the blades by length rather than by side. Measure the blade you are replacing, or check both arms, before you order.
| Position | Blade length | Arm fitting |
|---|---|---|
| Front pair | 600 mm / 24 in + 475 mm / 19 in — identical for saloon and Touring | Pinch tab |
| Rear | G21 Touring 280 mm / 11 in. G20 saloon no data available — no source fetched establishes ‘not fitted’. | Vehicle-specific rear fit |

Confidence in this data: High front, Medium G21 rear, none G20 rear
Checked against: Autodoc 3 G20, 3 Touring G21
Model and body-style splits: No front split between the saloon and the Touring. The catalogue also carries a Valeo VF824 at 600/450 Top Lock against the G20, which conflicts with every other entry on both length and fitting and is not treated as applicable here.
What Fitting Type?
Catalogue fitting for the BMW 3 Series: Front pinch tab (not Top Lock); rear moulded
Adapter warning. The Bosch set listed for this car is an Aerotwin Original (A-prefix). Aerotwin Originals ship with a single moulded, vehicle-specific adapter — they are not multi-fit and will not clip onto a different arm type. Bosch’s multi-fit products are the Aerotwin Retrofit (AR-prefix) and Aerotwin Plus (AP-prefix) ranges.
Right-hand drive. At least one supplier publishes a distinct right-hand-drive part number for this vehicle. On a UK car the blades sweep the opposite way to a left-hand-drive car, and the profile and stops differ, so buy the part the catalogue flags for right-hand drive where one exists — the references below say which.
Fit blades in pairs. Both front blades age at the same rate, so replacing only the streaking one usually means doing the other within weeks.
Recommended Wiper Blades
Bosch A605S
A605S (3397014774) 600/475 Pinch tab — A-series Original, flagged left-hand drive — same part on G20 and G21. Rear (G21) A280H (3397008005), A281H (3397008045), A283H (3397016466), all 280.
Valeo VF370
VF370 (574470) 600/475 Pinch tab left-hand drive; VM371 (574471) 600/475 Pinch tab right-hand drive. Note Valeo’s VM/VF prefix convention is reversed here relative to the VAG cars — go by the stated flag, never the prefix. Rear VM270 (574614) / HR28 (578561), 280.
Check by registration
The rear blade for this vehicle is not established in the data we checked. No data available. Use a seller’s registration lookup rather than buying on length alone.
How to Replace Wiper Blades
Changing the front blades on the BMW 3 Series takes a few minutes and needs no tools.
- Lift the arm away from the glass until it locks upright, and lay a folded cloth on the screen in case it drops.
- Release the old blade. Squeeze the two pinch tabs on the sides of the connector together and slide the blade off the arm.
- Compare old and new side by side before fitting — same length, same connector. If the adapter does not match, stop; forcing it damages the arm.
- Fit the new blade until the catch clicks home, then tug it gently to confirm it is locked.
- Lower the arm back to the glass by hand. Repeat on the other side, then test with plenty of washer fluid on a wet screen.
Never let a bare arm snap back onto the glass — a windscreen chipped that way is not covered by the blade warranty.
When to Replace Your Wipers
Wiper rubber hardens with UV and heat rather than with mileage, so a set on a car that is parked outside will usually be finished in about 12 months whatever the distance covered. Replace them when you see any of the following:
- Streaks or a haze left behind on the return sweep
- Juddering or chattering across the glass
- Missed strips of screen, especially at the top of the sweep
- Splits, curling or a shiny, glazed edge on the rubber
- Squealing that does not clear with a wash and a wipe of the rubber
Clean the rubber with a damp cloth every few weeks and clear leaves and grit from the base of the screen; both add months to a set. A blade that still streaks after cleaning is worn, not dirty.
Frequently Asked Questions
What size wiper blades does a BMW 3 Series need?
Sources disagree for the BMW 3 Series. 600 mm / 24 in + 475 mm / 19 in — identical for saloon and Touring Because the figures conflict, measure the blades on your own car before ordering.
What fitting type do BMW 3 Series wipers use?
The BMW 3 Series is catalogued as: Front pinch tab (not Top Lock); rear moulded Note that Bosch Aerotwin Original (A-prefix) sets carry one moulded, vehicle-specific adapter and are not multi-fit.
What rear wiper blade does a BMW 3 Series take?
Rear blade for the BMW 3 Series: G21 Touring 280 mm / 11 in. G20 saloon no data available — no source fetched establishes ‘not fitted’. Rear blades are normally a moulded vehicle-specific fit, so match the part number rather than the length alone.
How often should I replace BMW 3 Series wiper blades?
About once a year for most UK cars. Wiper rubber degrades with UV, heat and grit rather than with mileage, so a car parked outside will need blades sooner than the distance covered suggests. Replace them as soon as they streak, judder or miss part of the sweep after cleaning.
Does the BMW 3 Series need a right-hand-drive specific set?
Yes — at least one supplier publishes a distinct right-hand-drive part for this vehicle, listed in the references on this page. A UK car sweeps the opposite way to a left-hand-drive car and the blade profile and park position differ, so use the right-hand-drive part where the catalogue offers one.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
