Got my dear 03 allroad CPO two years ago. Nearing the end of the warranty, am agonizing whether to keep it. Moving from the snowy north to LA.

Mileage is still low (37k) and performs still wonderfully. Perhaps due to aging, from 6 month ago non-trivial failures are coming up (oil/turbo leak, thermostat failure, issues with anti-lock brake and suspension). Might be signaling more to come. Fortunately the new place in LA has reputable indep Audi mechanic (would save me bucks).

Any advice or experience on what trouble may lie ahead?

 

I say keep it and and maybe look into another extended warranty through this guy.

The suspension fixes a fairly reasonable due to Arnott Ind.The money you may loose in depreciation and the expense of buying a car of this caliber will make up for any issues you may have.One nice thing is when you replace turbos you can upgrade.I've got 123k+ on mine and only replaced front airbags but it's a V8

 

My 02 is at 100k and has had its share of problems. The obvious one for my year is the timing belt and everything that is associated with it. I fixed the front suspension and now all that's left is the motor mounts and front axles for now. If you need someone to look at your car in LA you should talk to Mike at Wicked Motorsports He paints a realistic future for your Audi.
