Original Quality Timing Chain Guide 079109514B for Audi A6L

Reference number 079109514B is a direct fit replacement timing chain guide manufactured to original equipment specifications for Audi A6L models equipped with the 3.0 TFSI supercharged V6 engine (engine codes CAJA, CGWB, CHMA, CJTB, CJTC, CJTE) and also compatible with certain Audi A7, A8, and Q7 variants sharing the same 3.0 litre or 4.0 litre TFSI and TDI power units, covering production years from 2008 to 2018. As an essential component of the engine timing system, this guide rail maintains proper tension and alignment of the timing chain, preventing chain slack, skipping teeth, or contact with the timing cover, thereby ensuring accurate camshaft to crankshaft synchronisation and protecting the engine from catastrophic valve to piston interference. Constructed from high grade glass fibre reinforced polyamide PA66 with advanced heat stabilisers and wear resistant sliding surfaces, this guide offers exceptional durability against high temperature cycling, oil contamination, and continuous mechanical friction over hundreds of thousands of kilometres. The mounting hole positions, curvature radius, and locking clip interfaces are replicated exactly from the genuine part, enabling straightforward bolt on installation without any modifications or shimming adjustments. Common failure symptoms include rattling or grinding noises from the front of the engine during cold start, illuminated check engine lights with camshaft position correlation fault codes, rough idle, and in severe cases, engine stalling or failure to start; replacing with our unit restores proper chain guidance, reduces noise, and extends the service life of the timing chain and tensioner. Every guide undergoes 100 percent dimensional verification, thermal shock testing from minus 40 degrees to plus 150 degrees Celsius, and friction wear validation prior to dispatch. The material meets OEM impact strength and fatigue resistance standards, ensuring long term reliability under aggressive driving and extreme weather conditions. Backed by a 24 month warranty against manufacturing defects, this timing chain guide offers workshops and individual owners a durable, cost effective solution that maintains your Audi A6L engine timing accuracy and prevents costly engine repairs. Installation is strongly recommended during timing chain replacement, tensioner servicing, or any major engine overhaul involving the front cover.
