Bad idle on cold start up
Hi Badderle,
I had something similar on my S8 v10. Mine was caused by a small air leak from one of the pipes at the back ( the fat braided one passenger side at the back. Replacing it gave me a smooth fast idle until aux air/fuel supposed after 15 seconds. Expensive hose around £90 from memory at stealer prices.
My car is Also 2006 S8 v10 with 165,000 miles on it.
Good luck
Richard
