Audis, especially Quattros, are an expensive nuisance to maintain.
The first step of anything to do with the engine compartment is "remove front of car".
They don't optimize the layout one bit for minimizing cost/maximizing ease of maintenance. I have a friend with an RS6 that sat unused for years because it needed some cam sensor or actuator thingy serviced to idle right and pass smog, to do the job required pulling the engine due to packaging constraints. A job like that isn't just expensive, it requires finding a mechanic you actually trust to do the invasive job properly, unless you can DIY.
I'm a DIY type, and that has me firmly in the domain of mass-produced Japanese economy-sports cars. They're an absolute dream to work on. I can change the timing belt on my current car without even jacking it up off the ground let alone tearing the front of the car off, using nothing but a few hand tools.
