Hi guys and girls. Loving the 8 had it over a month now. Just wanted some guidance. The car has been serviced yearly by previous owner with non audi parts. Planning to get it serviced by audi tech with all original parts in the very near future. Do these cars have EGR valves etc that need cleaning as my one is on 117k at present. Is there anything I should do that the service does not pick up? I know about gearbox service that is on my list already.
Brake fluid?
Coolant?
Thermostat?

Cheers guys.
