Product Description
This hydraulic timing chain tensioner with OE number 079109218D is a direct OEM replacement specially engineered for Audi A6 C6 (4F chassis) equipped with 4.2L V8 gasoline engines (BBK, BAT, BHF, BAS). All external dimensions, thread parameters, internal one-way valve structure and spring tension strictly match factory original standards, supporting direct plug-and-play installation without grinding or adjustment during timing system overhaul.
- High-strength forged alloy steel housing with anti-rust treatment
The tensioner body adopts precision forging high-carbon alloy steel, surface passivation anti-corrosion treatment to resist long-term erosion of high-temperature engine oil inside V8 engine compartments. Thickened thread wall prevents sliding during disassembly and assembly; built-in high fatigue-resistant spiral spring maintains constant pre-tension after thousands of cold start cycles, effectively solving timing chain slack, elongation and abnormal vibration of original aging tensioners.
- Upgraded one-way hydraulic valve to eliminate cold start rattle
Optimized internal hydraulic damping and one-way check valve structure, which rapidly builds stable oil pressure within 2 seconds after cold startup to eliminate obvious rattling and ticking noise from the engine bay. The hydraulic buffer absorbs chain vibration during acceleration, deceleration and high-speed cruising, effectively limiting the risk of timing chain jumping teeth, and avoiding severe engine damage such as valve and piston collision caused by timing disorder.
- Wide compatible vehicle range for VAG 4.2 V8 platform
Main applicable models:
- Audi A6 C6 Sedan/Avant/Allroad quattro 4.2 V8
- Audi S4 B6/B7 4.2 V8
- Audi A8 D3 4.2 V8
- Porsche Cayenne 4.2 V8 gasoline
Perfect matching with timing chain guides, cylinder head mounting holes and camshaft timing chains, no auxiliary gaskets or modification needed during assembly.
- Strict multi-process factory inspection & obvious fault repair effect
Each tensioner undergoes hydraulic pressure retention test, high-low temperature engine oil immersion aging test, spring compression fatigue cycle test before delivery. It thoroughly fixes typical timing system faults of A6 C6 4.2 V8: cold start chain ticking, unstable idle speed, power attenuation, engine fault light activation and hidden danger of chain jumping teeth.We support one-stop bulk procurement, flexible MOQ, customizable neutral export packaging, stable spot inventory and 12-month quality warranty, serving global Audi luxury car repair shops and cross-border auto parts distributors.
