It's a long shot..

I've got a 55 plate A3 petrol 2L turbo quattro sport, i need to tow a horse trailer (the trailer and the horse weigh approx 1500kgs) does anyone have any experience of towing with the same model?

look at the side of the door for a sticker or in the owners manual --- there should be a towing maximum. a horse trailer sounds a little heavy ....
