What sort of noise would a faulty engine mounting make? When test driving the S4 I thought it sounded like the front offside wheel bearing was rumbling excessively. (I also noticed a faint different noise when engaging the clutch at low speeds) I guess tyre noise will be worse with 18" tyres over 17 but there was certainly more noise from the front offside which can't be right? I mentioned this to the salesman and he called a mechanic over who suggested it could be the engine mounting. He said it was a common fault on S4? But from previous experiance these guys talk a load of s*&t. It hasn't had its 100point check yet so they will look into it then.
