Mercedes-Benz W211 E-Class SBC Sensotronic Anti-Lock Brake Pump OEM A0054319712Q2 / 0265250111

Important before you buy: if your W211 is a 2003–2006 model year, Mercedes-Benz issued a 25-year, unlimited-mileage extended warranty covering the SBC hydraulic pump unit, following a 2005 NHTSA safety recall for a loosening ground wire connection that could trigger a false SBC fault. Check with a Mercedes-Benz dealer using your VIN before purchasing — you may be entitled to a free dealer replacement, and some SBC fault symptoms trace back to that ground wire, not the pump itself.

If you've already confirmed you need the pump, this is the genuine OEM SBC (Sensotronic Brake Control) hydraulic pump unit for the W211 E-Class. It retains the original mounting bracket and connector configuration.

Product Highlights

• Genuine Mercedes-Benz OEM SBC hydraulic brake pump
• OEM part number A0054319712Q2 (Bosch manufacturer number 0265250111)
• Front-mounted, direct replacement
• Exact item pictured will be shipped

Vehicle Fitment

• Mercedes-Benz W211 E-Class, SBC-equipped models

This listing does not have a confirmed year range in our own records — SBC was used on early W211 production before Mercedes moved to a conventional hydraulic brake system on later model years. Confirm your exact part number (A0054319712Q2 / 0265250111) matches your original pump before ordering — this is the only reliable way to confirm fit given the mixed brake systems used across the W211's production run. Does NOT fit W211 models with the conventional (non-SBC) hydraulic brake system, or any W212 (2010+) E-Class.

What Is Included

• SBC hydraulic pump unit, as pictured

Only the components visible in the photos are included — brake lines and mounting hardware are not included unless shown.

Condition

Pre-owned genuine OEM unit. May show normal cosmetic wear from age and prior installation. Check the photos closely for:

• Connector pins and housing condition
• Brake line port condition — corrosion or damage
• Mounting bracket condition

You will receive the exact pump shown, not a stock photo or substitute unit.

Verify Fitment Before Ordering

Compare against your original before ordering:

• Part number A0054319712Q2 / 0265250111 matches your original unit's label exactly
• Your W211 has the SBC brake system (not conventional hydraulic)
• Connector shape and pin layout match

For additional fitment support, send us your VIN and a clear photo of your original pump's part number before ordering.

Why Choose a Genuine OEM Mercedes-Benz SBC Pump?

• Correct hydraulic pressure calibration for the SBC electro-hydraulic system
• Original connector — no rewiring needed
• More reliable than a rebuilt or unknown-history unit on a safety-critical brake component

This is a single unit from one donor vehicle — genuine SBC pumps are becoming harder to find as these vehicles age.

Installation

Professional installation by a shop experienced with SBC systems is strongly recommended — this is a safety-critical, electronically-controlled brake component requiring proper bleeding and system initialization after installation, not a standard brake job.

An SBC fault message isn't always the pump itself — on this platform, a loosening ground wire connection is a documented cause of false SBC faults (the subject of a 2005 factory recall). Scan for stored fault codes and check the ground connection before assuming the pump is the cause.
