Citroën C4 Wiper Blades — Size & Fitting Guide (2021–2025)

Wiper Blade Sizes at a Glance

Blades are labelled by length, not by side: supplier catalogues do not state which of the two front blades belongs on a right-hand-drive car’s driver arm.

Wiper Blade Sizes

Front blade lengths and arm fitting for the Citroën C4, 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.

Confidence in this data: High front, none rear

Checked against: Autodoc C4 III B

Model and body-style splits: The e-C4 X (C43 saloon) is a separate model in the catalogue. These figures do not apply to it.

What Fitting Type?

Catalogue fitting for the Citroën C4: Top Lock

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 ranges are Aerotwin Retrofit (AR-prefix) and Aerotwin Plus (AP-prefix).

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.

How to Replace Wiper Blades

Changing the front blades on the Citroën C4 takes a few minutes and needs no tools.

1. Lift the arm away from the glass until it locks upright, and lay a folded cloth on the screen in case it drops.
2. Release the old blade. Press the release tab on the top of the connector and pull the blade square off the arm — it unclips rather than sliding.
3. 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.
4. Fit the new blade until the catch clicks home, then tug it gently to confirm it is locked.
5. 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 Citroën C4 need?

The catalogue front set for the Citroën C4 is 600 mm (24 in) and 400 mm (16 in). The catalogue does not say which of the two goes on the driver’s arm of a right-hand-drive car, so measure the blade you are replacing rather than assuming the longer one is the driver’s.

What fitting type do Citroën C4 wipers use?

The Citroën C4 is catalogued as: Top Lock

What rear wiper blade does a Citroën C4 take?

No data available for the rear blade on the Citroën C4. Where suppliers disagree or list nothing, we say so rather than guess — check by registration.

How often should I replace Citroën C4 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.
