Is your Mercedes steering feeling off? This might be the culprit. This is a replacement power steering solenoid valve that fits a ton of Merc models from the early 2000s onwards. We're talking S-Class (W220, W221), E-Class (W211, S211), ML-Class (W164), R-Class (W251), CLS (C219), SL (R230), SLK (R171), and more. The part numbers you need to match are A2214600184, 2214600184, A2114600984, 2114600984, and a few others – check your old one! It's a critical little part that regulates the fluid pressure in your steering rack, giving you that smooth, power-assisted feel. It's got a fail-safe built in too, so even if the hydraulics go, you'll still have manual steering (safety first!). Made from high-strength steel for durability. Just make sure it matches your car's OEM markings to be sure. A straightforward fix to get your luxury ride steering smoothly again without paying dealership prices.
