I took my FR in to get the window skoosher fixed and I told them about a bit of corrosion on one of the wheels when I got there. Later that day when I picked it up they told me they had ordered a replacement wheel under warranty no questions asked!
When the wheel arrived, I took it in to get it changed over but there was a
problem when I went back to pick it up. Turns out they had taken the wheel off, changed the tyre and fitted it to my car before they noticed the new wheel was a different colour!!! Apparently seat have changed the colour of the andromeda wheels and they don't have any stock (and won't get any more) of the wheels in the colour I have.
Been meaning to get back to them about this 'cos I've since noticed that 2 other wheels are also corroded.
