On the 2007-2012 Audi S8 5.2L FSI V10 (BSM), the D3-generation S8 uses the 5.2L FSI V10 (shared lineage with the Lamborghini Gallardo/R8 V10). Its timing is driven by chains with plastic guides and hydraulic tensioners located at the rear of the engine. Over time and with deferred oil changes, the tensioners and guides wear, producing a rattle on cold startup that can persist. If a guide breaks or the chain skips, valve-to-piston contact can cause catastrophic engine damage. Access is poor (rear of the V10), making this an engine-out-level job and one of the most expensive risks on the D3 S8.

This issue also affects: Audi A4, Audi A1, Audi A5

Common Symptoms

  • Rattle from engine on cold startup
  • Metallic chain noise from rear of engine
  • Rough running or misfire if timing has shifted
  • Check engine light for camshaft/crankshaft correlation

How to Fix

Investigate any cold-start rattle promptly: inspect tensioner travel and guide condition. Replace the timing chains, tensioners, and plastic guides as a set with updated genuine parts; this is a major, labor-intensive repair (often engine-out). Strictly follow short oil-change intervals with the correct grade to maximize tensioner/guide life, and address any low-oil-pressure condition immediately. Do not drive a V10 with a persistent timing rattle.

Typical repair cost:$2,500 - $6,000
