Replaces Mercedes-Benz OE 2045400317 (also written A2045400317, A 204 540 03 17). Cross-references to Febi 38371, SWAG 10 93 8371, VEMO V30-72-0038, Bosch 0 986 594 546, MEYLE 014 800 0112, Bremi 50499, Standard ALS1858. Confirm the OE number on your original sensor before ordering. This is an aftermarket replacement part, not a Mercedes-Benz Genuine (OEM) part.
Engineered for the rear axle of Mercedes-Benz W204-platform vehicles that carry OE 2045400317. On W204-series cars the rear-axle sensor number is shared across left and right — both sides use the same number, two pieces required per axle. Do not confuse with front-axle sensors (W204 front uses the 204 905 xx 00 family, e.g. A2049057900). Exact coverage must be checked with Part Finder or your VIN
Built as an active Hall-effect wheel speed sensor (12V supplied, not passive inductive). 2-pin sealed connector, sensor body with integrated wire harness in one assembly (~1035 mm overall lead length per Febi/Bosch; some brands measure 945–990 mm cable-only — both are the same fitment). Returns clean rear-axle wheel-speed signal to the ABS / ESP module. A damaged tone ring, broken harness or worn hub bearing will still trigger codes — this assembly replaces only the sensor and its integrated wire.
Covers Mercedes-Benz W204-platform rear-axle sensors: C-Class W204 (sedan), C-Class S204 (wagon), C-Class C204 (Coupe), using OE 2045400317. Does not fit C-Class W203 (2001-2007, uses A2035400217 family), C-Class W205 (2015+, new number), GLK X204 (rear uses 2045401317 family), or any front-axle position. Note: some aftermarket pages list 2049050100 alongside this number — 2049050100 is a front-axle number, not an equivalent of 2045400317; do not substitute across axles. If your original reads 204 905 xx 00 it is the front axle — verify front vs rear before ordering.
Lift the rear wheel, remove the sensor at the axle housing, disconnect the 2-pin plug, unbolt the old sensor, seat the Yttrotechnix assembly (body + integrated wire as one unit), reconnect at the ABS/ESP module, reassemble, then clear ABS / ESP fault codes with a scan tool. When in doubt, send us your VIN — we confirm fitment before you install.

Mercedes-Benz W204-platform rear axle: C-Class W204 (sedan), C-Class S204 (wagon), C-Class C204 (Coupe).

FAQs
Q1: What is the difference between OEM and Aftermarket parts, and how do I select the right quality level for my needs?
A: OEM (Original Equipment Manufacturer) parts guarantee exact fit and factory quality, typically at a higher cost. Our Aftermarket parts are sourced from certified manufacturers, often offering comparable performance and superior value. We clearly label all products to allow the customer to make an informed choice based on budget and required lifespan.
Q2: Since you are a global supplier, how do I calculate total shipping costs and estimated delivery time to my country/region?
A: Shipping costs are calculated based on part dimensions, weight, and the destination country during checkout. We offer multiple options (e.g., Economy, Express) with transparent, real-time tracking. Delivery times are clearly displayed and factor in customs processing for international orders.
Q3: What is the warranty period on your auto parts, and what does the warranty actually cover?
A: Most new parts carry a minimum 12-month limited warranty covering defects in material and workmanship, excluding wear and tear and improper installation. The specific warranty details (period and coverage) are clearly listed on each product page.
Q4: How secure is my personal and payment information when placing an order on "okcarpart" ?
A: We use industry-leading security protocols, including SSL encryption and reputable global payment gateways (TT, Visa, Mastercard, PayPal). We strictly comply with global data protection regulations to ensure customer information is secure and protected against fraud.
