I have a few questions since I want to allow my now 7.5 year-old Audi V8. Would be nice if someone could help me with tips.
How should I do this best, first to the Tüv (need, as I have already read a full acceptance) and then to the workshop after the fault area?
Since the vehicle has been standing for a long time, I must certainly change oil, water brake fluid, what does this look like for the transmission oil for the automatic and the servo oil for the steering and the coolant of the air conditioning system?
There's still old gas in the vehicle, I know the gasoline can get bad, do I have to empty it all?
Can I use this to try the car without risk of engine damage?
Is it enough to pump the tank and then refuel it?
And if so, what about the old fuel that's still in the petrol lines and the injection system?
Does anyone know how to get the rear brakes back? they are rusted (and yes, unfortunately the handbrake was put on at that time)
Does anyone have a tip like me to get the most simple one? Caramba, maybe, if you can walk, brake cleaner?
What else to consider?
I would be grateful for helpful answers.
