Reference number 079109469AA is a direct fit timing chain guide for Audi 4.2 V8 engines (BNK, BHF, BAT), fitted to A6L C6, A6 Allroad, S4 B6/B7, RS4 and Q7 from 2003 to 2010. This left lower guide sits on the main timing chain between the idle gear and crankshaft. It maintains correct chain tension and alignment, preventing slack, tooth skipping, or cover contact, thus safeguarding valve-to-piston timing.
Made from glass fibre reinforced PA66 with heat stabilisers and low-friction surfaces, this guide resists thermal cycling, oil attack, and continuous friction over high mileage. Mounting points and curvature match OE exactly, enabling straightforward bolt-on installation.
Common failure signs include cold-start rattling, check engine lights with camshaft correlation codes, rough idle, or even stalling. This guide is a known weak point in 4.2 V8 timing overhauls; replacement restores chain guidance, cuts noise, and extends tensioner and chain life.
Each guide is 100% dimensionally checked, thermal shock tested from -40°C to 150°C, and validated for wear. It meets OEM impact and fatigue standards. Backed by a 24-month warranty, this guide offers a durable, cost-effective fix for A6L timing accuracy. Installation is recommended during chain or tensioner replacement, or front cover overhaul.
