: horn noise under part throttle??

07-12-2010, 02:24 PM
another issue ... under say 25-35% throttle i get a fog horn sort of noise that isnt their under full throttle but only when you get the same 25-35% throttle.. it only started happening once i put my silicone hoses on ... now yes they are for an S4 but the allroad was basically the same engine and fitted on with little effort.. i have also double checked every clamp and their is no leaks at all....

could it be from my DV's ? these are new 710's sound odd thats all ...

any help would be great
