It could be from the aircon !

aircon?how would i check that and if it is what to do?

The aircon condenses the air air and the water runs out of the evaporator.
If the water under your car is from the aircon it is nothing to worry about, its normal.

Mine did this recently (if it's the same, 1.8T) and I had to replace the large black metal pipe that goes across the top of the engine (from front to back) as the bleed screw was leaking, easy enough job 1/2 hour and £40 from the *******

I was told by the ******* this is a commom problem and they had the part in stock to prove it

Yeah, no need to do the whole pipe, mine was just the screw... took all of 2mins to change with the right alan key!

lol, £40 still aint too bad for an Audi part from the Audi dealer!!
I initially thought it was a big job... & was thinkin in the hundreds for a repair... but got away with a £2 screw/washer! Job done!
