I am really interested in buying this certified 2006 Audi A4 that I saw last weekend at a dealer's lot. I test drove it and the final offer from dealer is 23,900 + TTL
Specs: 2006 Audi A4 (registered Sept 2006)
2.0T Automatic Quattro
It is certified upto 6yrs/100,000 miles.
Is this a good deal and how is the reliability of this car? Can I trust the Audi certified warranty?

It is a great car to drive. However, you must accept the inconvenience of carrying a quart of oil in your trunk, check the oil level at every time you refill your tank and use roughly a quart of oil every 1200 miles (Audi's level of acceptable oil usage). You will need about 8 quarts between the recommended oil change interval of 10,000 miles. iI you are lucky, or rather if the turbine is not engaged a lot, it might use less.

It may not burn and it may not leak at the bottom and still use oil. The problem is that the the PCV pump system's check valve, the one tied directly to the intake manifold after the turbo, is not closing consistently when the turbo inreases the pressure. The increased pressure then leaks into the crankcase that the other end of the PCV pump assembly is unable to vent completely to the pre turbo section of the intake manifold. The oil leaves in part through the orifice of the dipstick tube, You pull out the dipstick and you will find oil residue on the inlet shoulder. You will also find oil residue on the cowling.

Yeah but if it was being pushed out the dipstick hole, the engine bay would be an awful mess. You can imagine this by spraying a quart of oil into your engine bay.
I think a bad PCV could definitely cause more oil burning however, forcing oil past the rings and giving us the phenomenon called "blowby".
Another sign of blowby might be a very oily air filter.

Check your owners manual - there is likely a re-set procedure needed after changing the battery in the key fob.

Spraying oil into the engine compartment would be a sign of a plugged PCV valve with oil squirting out. Here, the the valve, which is suppose to close when there is positive pressure in the in-take manifold is staying open. the only thing you will see is an oil residue on the cowling, near the oil fill cap and oil deposit on the ring at the end of the dipstick handle and the seat underneath it. If you have instrumentation you can also measure the pressure drop at the turbo output, where the 0.9 Bar normal pressure will drop by about a tenth, because of the leak into the crankcase. We are not talking about a very large amount of oil. My loss is about a quart in 1800-2000 miles. Used to be a quart every 3000 miles. There are lots of suggested fixes.

Thank you for that explanation, but still, a quart of oil is somewhere in the engine compartment (or am I misreading what you are saying?). Where does the oil go, this 1/2 quart every 1,000 miles? Either burn or leak, that's it right?

That is right. Some burns no doubt, though my tail pipe finger test comes up negative. Evaporation into the engine compartment might be expelled by the fan, though I have distinct oil deposit on the cowl around the oil refill cap. Audi states that even 1 quart per 1000 miles is acceptable engine performance and I am half of that.
