Oil change 2.0 tdi?? DIY or Dealer? 10k or 20K?

So on night shift cleaning the car (as you do) and was thinking, as my audi is only a year old and done 10k i usually change the oil and filter around this time on any car i have had. However the car tells me i still have over a year or 9700 miles until the oil needs done.

How can audi justify not having an oil change at 10k?

Also can i do an oil change myself at 10K without affecting the warranty?

Oh and i got a free 2 year service plan when i bought the car, now does this mean everything is included when service time comes or is that minus an oil change?

Views and opinions appreciated

Cheers for the reply mate. Yeah it doesnt hurt to change it every 10K. Im going to keep up with the audi service history but as you say for peice of mind id like to do it myself every 10K or 1 year. Would you use audi genuine oil or the equivalent audi recommended oil that you can pick up from say halfords? I have the 140 2.0 tdi btw.
