Just purchased 2002 A6 3.0 Quattro
I just got a 02 A6 3.0L Quattro with 125k miles on it. I called the Audi dealership and gave them the VIN # to look up the service history. The prior owner did all the recommended maintenance at the dealership including the timing belt at 109k. At 120k, the prior owner complained of knocking noise when accelerating. He had a fuel injection service performed and it seems fine now. He also complained of intermittent Check Engine lights going on and off. They reset the computer module and I see no issues now. The dealership said I may need to replace a cat converter soon.
1) Any advice on what maintenance I should do now? Is it likely I will have a cam lobes issue?
2) What brand and weight of oil should I use?

Cats are a common failure for the 3.0.

Thanks for the input everyone.
Is it OK to go with synthetic Mobil 1 0W-40 now at 125k miles? The prior owner had work done at the dealership, so I do not know if they used dino oil.
Is it OK to go with an aftermarket cat?

The advantage of oem cats through a dealer is you should be able to strong-arm him into guaranteeing the CEL goes away or fix it (at no further charge). I am still fighting occasional CELs after installing Billy Boat cats. In retrospect, I should have lived with the CEL and used my Innova 3130 ($130) to clear it. Unless you have emissions checks in your state, my advice is ignore it.
