Product Overview

The camshaft adjuster, OEM number A2760503700, is the right-side intake camshaft adjuster fitted across an unusually wide range of Mercedes-Benz models with the M272 and M276 V6 engines, including the C-Class (C300, C350, C400, C43 AMG), E-Class (E300, E350, E400, E450), E-Class Coupe (W207), CLS-Class (CLS350, CLS400), and models on the W166, W212, W218, W221, and W222 chassis, spanning model years 2011-2020. Since this adjuster covers so many Mercedes sedan and coupe models sharing the M272/M276 engine family, it's a genuinely high-turnover part for anyone stocking Mercedes valvetrain components.

Worn or failing units typically show up as a rattling or ticking noise from the engine, a check engine light with a camshaft timing fault code, rough idle, or reduced engine power. GSK Auto manufactures this camshaft adjuster to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this is specifically the right intake adjuster, and separate part numbers exist for the left intake and both exhaust camshaft adjusters on the same engine, so it's worth confirming exact position (intake vs exhaust, left vs right) with your customer before shipping.)

What Is a Camshaft Adjuster?

Function: The camshaft adjuster, also called a VVT (variable valve timing) sprocket, adjusts the rotational timing of the camshaft relative to the crankshaft, allowing the engine to optimize valve timing for different speeds and loads to improve power, efficiency, and emissions.

Working Principle: Oil pressure directed by the ECU flows into internal chambers within the adjuster, rotating the camshaft slightly forward or backward relative to its drive sprocket, which advances or retards valve timing based on real-time engine operating conditions.

Importance: Precise camshaft timing is essential for proper combustion, and a failing adjuster - whether from internal wear, oil control valve issues, or debris contamination - can throw off valve timing enough to cause rough running, reduced power, and camshaft timing fault codes.

Common Failures & Signs: Internal wear or oil control valve contamination affecting adjuster response. Rattling or ticking noise from the engine, particularly noticeable at startup. Check engine light with a camshaft position or timing fault code. Rough idle or reduced engine power linked to incorrect valve timing.
