Audi A4 Problems

No, I don't think it is asking too much given its age and low kays. What Audi has done by covering part of the cost is pretty much industry practice, but it's hard to swallow in some case when there has been such a catastrophic failure like yours. I would press your case, even consider taking it to the consumer affairs people in your state.

I wouldn't rely on your mate's check, take it to an Audi dealer and get it properly diagnosed and fixed.

VW/Audi engines are known to use oil from new, but they usually settle down once the engine is run in. The rate of oil usage Audi has quoted you is about what you would expect. A litre per 1000 km is too much, however, and it would seem Audi accepts as much given they are prepared to do some rework on the engine. Have the work done as the company recommends and keep track of what oil is used after the rework.

It’s most unusual for a fuel-injected car to flood, but if it is flooding as you say I would check the fuel injectors, one or more could be worn and leaking.

The dealer is in the best position to determine the cause of the problem and rectify it. I wouldn’t be too concerned, even brand new cars can have problems, and hopefully yours will run reliably again once it’s repaired.

A SECOND-HAND car will be a better model and have more equipment than a new car for the same price, but you are buying a car that has done quite some mileage in the hands of someone you don't know. There are risks buying a used car because you don't how previous owners have treated it. If you're prepared to take them, buy a car with a known service history and have it thoroughly checked by a specialist in that brand.
