your car will never know what kind of oil filter is bolted on it, its not that smart.
the noise you hear is your really cold oil not being where it is supposed to be first thing in the morning. and the fact that it is thicker and its harder to get it there. the only reson it does not do it again after shutting it off and re-starting is that now, the oil is where it needs to be. only thing you can do there is maybe get a lower weight oil, with the turbo, you should be running synthetic, are you ? and it should be 5-30 at the very most. in the winter something thinner will not hurt.

I do not much believe in coincidences. Last night the "check engine" light came on. The car has normal oil level and no oil pressure indication has come on - my wife drives the car and I have asked her to be very attentive and report to me all console messages. The only thing that was done to the car, of which I can think, is that the oil filter was an aftermarket filter - not Audi. However, this should not matter much since it is one of the filters that is recommended on the outside of the Audi filters - it was not a Fram, probably AC or Purolator. My local Advance Auto Parts just informed me that they have one K&N oil filter for the Audi. I will pick it up for next time.
There is another issue, once the weather turned cold, 35 degrees for a few days, the engine makes an awful noise when it starts cold. It is a very loud grinding, rasping, and shrieking sound. If the car is turned off and immediately started again, the sound does not come back. It happens only when the car is dead cold after a long rest. I have a feeling that it may be a belt, but I am not sure. Having had the starter problems with my other Audi, I hate to think that it is happening to this car also. The key however, does return to position two when the car starts - unlike with the 90S that kept the starter engaged all the time. As someone pointed out here, I will ask my wife to lighten-up her key chain, just in case.
Any help would be appreciated. Thank you.
