My view is as follows:
The 60,000 km service is a big one and includes the expensive DSG oil. A petrol engine will also need spark plugs then and a 4Motion will need Haldex oil - not that you need to worry about those two. Is $1,200 too much? Well, it's a lot ... but then dealers charge at least $150 per hour + GST = $165 for labour. I assume if you wanted to save the labour charges, you'd already be doing the minor services yourself? My small independent garage charges $500 for a minor service but I buy the oil and filter for under $100 and save $400 each time doing it myself.

I think new brake pads and rotors at 60,000 is quite reasonable in terms of wear. These days rotors are designed to be a consumable item usually requiring change with the pads. Others have said the parts are expensive so I guess $757 is justified.

And $571 for a new battery - well if it's a huge double-length one in the boot like mine then it's cheap. Maybe you should consider yourself fortunate if your car will allow you to fit alternatives. I'm told some Audis will only accept an OEM one after the technician has entered the new battery's serial number and the car's computer decides that number is within an acceptable range of OEM numbers!
