However, if you flick the centre cap off the alloy, the offset should be written on the alloy in there, marked with ET before the offset number.

Or... using the 3 letter option codes in the front cover page of your service manual, enter all of the codes into this tool and of them will have info including the offset about your wheels.

Hi. I got the part number from Audi

Ok thanks I shall do the above..

So there isn't a standard offset for 18" ?
