Thanks for the reply guys. It's a 211 bhp version atm and the garage said it would probably go to about 250 with more torque (sold me the dream basically). I have not had a single problem with oil on it at the moment, does this only happen when remapped? Jealous about your S5- drove a friends the other day!
No nothing to do with a remap. Its just a design fault on most A4, A5 and Q5 2.0TFSI models built around those years. For the A5 its all 2.0TFSI pre-facelift (2008-2011). The problem causes the car to consume stupid amounts of oil. I was getting through 1lt oil every 400miles...
A good thread over on A5OC about it:

Basically...Audi have finally admitted fault and now fix the issue free of charge following a fail on their oil consumption test (consumes more than 0.5lt after 621miles). This will either be a stage 1, which is software (rarely bother with this has it doesn't help...), stage 2, which is replacement of rods and pistons (I had this done), or Stage 3, which involves replacing the engine block if the engine bores have been damaged.
The only times I've seen people asked to contribute to the cost is when they don't have full audi service history, and don't have exact details of oil used at any indy service, or if they have modified the engines through remaps, etc. When you consider the cost of stage 2 is about £4k and stage 3 is £12k...i don't think any proportion towards it would be nice...!
My advice is just to hold fire and monitor your oil for at least another 1000miles. See if the oil gauge drops or if your oil warning light comes on. If it does, fill it up with 1lt as requested, reset the odometer and record how much the oil goes down after 600miles. If its more than halfway, get it booked in for the fix.
After that....remap away to your hearts content
Cheers buddy. Have to say I am enjoying the S5 quite a lot....!
