Quattro Transmission fluid change

[dociain]

I have an April 2006 Saloon with 18,000 miles on the clock. Like most owners I have a Long life service interval and the car was serviced last at 13,800 miles , the next one due in 5,000 miles
I recieved a card through the post from a local Audi dealer saying my car needed a quattro transmission fluid change but I can't see anything mentioned re this in the service manual
Does it need doing or are they just touting for business
Help and advice would be most appreciated

I've just had my first service - when I got the car back they had put a little service sticker in the top corner on the windscreen telling me it needs a brake fluid change in September. No mention of transmission fluids mind.......
