Our original quality timing chain tensioner guide rail, OE number 021 109 467, is a direct replacement part compatible with Volkswagen CC, Phaeton and Touareg. Manufactured strictly following factory original dimensional standards, this key bar tensioner perfectly fits the engine timing system without modification, effectively solving abnormal timing chain rattling, loose chain and unstable engine idle issues caused by worn or broken original guide rails.
