Hi,
Welcome to the forum. No cargo net as standard I'm afraid. The service plan question needs a bit more of an answer, so apologies if this sound long winded.
The standard Audi service plan for the Q2 covers two services, and absolutely nothing else for around £530. But a good option in my mind is Audi Complete. The dealer will quote for this depending on your mileage and it's only available for cars up to one year old and haven't had the first service. In my case I pay £20 per month for three years with mileage set at 11k per year, and for that I get 3 services (the car is on fixed regime so serviced every year) brake fluid change, a/c service, discs, pads, wipers, key batteries and MOT. For me Audi Complete cost is £720, so for me it works out a better deal than just the two services, Definitely worth getting a quote.
