Mercedes C-Class Wiper Blade Size & Fitting Guide (2021-2024)
Wiper Blade Sizes
Front blade lengths and arm fitting for the Mercedes C-Class, 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 — longer blade | 550 mm (22 in) | Bayonet |
| Front — shorter blade | 550 mm (22 in) | Bayonet |
| Rear | Not fitted on the saloon; S206 estate no data available | Vehicle-specific rear fit |

What Fitting Type?
Catalogue fitting for the Mercedes C-Class: Mercedes bayonet
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 — no set listed for this vehicle
Bosch does not list a wiper blade against this vehicle in the catalogue data we checked. No data available. Do not substitute the part from the previous generation of this model — the arm interface often changes between generations. Check by registration on the seller’s own fitment tool.
Valeo — no set listed for this vehicle
No Valeo front set is listed against this vehicle in the catalogue data we checked. No data available. Valeo singles of the right length may still fit, but only if the adapter matches the arm — confirm the fitting type first.
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 Mercedes C-Class 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. Press the bayonet catch on the underside of the connector and pull the blade straight off along the line of 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 Mercedes C-Class need?
The catalogue front set for the Mercedes C-Class is 550 mm (22 in) and 550 mm (22 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 Mercedes C-Class wipers use?
The Mercedes C-Class is catalogued as: Mercedes bayonet
What rear wiper blade does a Mercedes C-Class take?
Rear blade for the Mercedes C-Class: Not fitted on the saloon; S206 estate no data available Rear blades are normally a moulded vehicle-specific fit, so match the part number rather than the length alone.
How often should I replace Mercedes C-Class 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.

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 →
