Hello everybody,Have a Audi A6 sline ultra Automatic 2015,I notice that when the car reaches over 50kms there is a wierd sound like as if it wants to up an other gear,It's very smooth going from 1st to 7th gear but strange noise as if its wants to find a other gear,First I thought it's was tire noise so I changed them all and it's not as noisy now so that made a difference but just can,t figure out what the strange noise is,Had the wheel bearing checked and all fine,Any thoughts much appreciated
Thanks in advance Harry
