Febi Bilstein 171985 - variable valve timing gear

The Febi Bilstein 171985 timing gear is a part of the variable valve timing mechanism (VarioCam / Camshaft Adjuster) fitted on the camshaft. The part has 44 teeth and is placed on the inlet side of the timing drive, where it transmits drive from the chain or belt to the camshaft while allowing the valve timing to be adjusted depending on engine speed and load.

Application

The part fits selected engines installed in Mercedes-Benz vehicles from 2002-2018, including the Sprinter (906), C-Class (W203, S203, CL203, W204, S204), E-Class (W211, S211, W212) and CLK (C209, A209) and CLC (CL203). It corresponds to the original Mercedes-Benz catalogue numbers A271 050 06 47, A271 050 08 00, A271 050 09 47 and A271 050 14 47 - before buying, compare the OEM number on the old part, because engines of this family came in several variants.

Why replace with an OE-quality replacement

The variable valve timing gear is a precision component - its wear (loose seating, large play on the spline) leads to incorrect operation of the VarioCam system, camshaft sensor error codes and uneven engine running. Febi Bilstein is a German manufacturer of replacement parts supplying OE (Original Equipment) class components to workshops throughout Europe, producing among other things on commission for car groups.
