my central locking system is not working thru the use of the remote. i already replaced the battery of the remote and the same is happening. now i have to lock and unlock manually using the key and it's only the driver's door that's working and the rest are not. and the lock/unlocking button inside by the driver side is not working either. but the alarm system is working. anybody can help me. thank you very much.

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. Here is one http://www.golfmkv.net/blog/archives/23. Here is another http://deviantspeed.com/the-ultimate-20t-pcv-fix.

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.

Okay got it. I could live with a quart every 2,000 as long as it never got worse. I don't see Audi doing anything about it anyway, since it is "in spec".

1998 Audi A4 Quattro Power Windows

I just purchased this 98 Audi A4 and I rolled the back drivers side window down and it wont go up. I can turn the key on and pulled the window switch and it will go up about 1-2 inches and automatically go down. I got it up by turning the key on and my husband held the window up and then I had to turn the key off and back on and it would roll up another 1-2 inches while he held it up. I had to do this til I got it completely up and it stayed. The drivers side front also don't work. I was wondering what might be wrong with it. Can anyone help me with this?

You are of course absolutely right. Audi won't do anything on the basis of the oil loss, after all there are some New Beetles, without turbo which use even more oil. However, Audi might be forced to do something because of the pressure leak from the turbocharged section of the manifold. Once the check-valve fails in the PCV assembly, the turbo can never develop the 0.9 Bar (about 13 psi) pressure. This impacts engine performance. All the proposed fixes on the net are addressing this performance loss, not the issue of oil loss. The oil loss is just a symptom.
