When it is ultra cold out...why wouldn't I want to warm up the engine..? really need some input guys
I started it and went for a quick shower and came back to find this mess.
Any reason why I shouldn't warm up? On the other hand, I would have been 5 or 10 miles on the road and face the smoke screen? I don't know... I think in a way I am lucky that it happened on the driveway instead of getting stuck and waiting for tow truck.../ freezing my *** off etc...
I thought that if the engine is warm, it would be better to drive it then instead of cold engine / more stress...

turbos need oil, driving the car will circulate the oil better than letting it idle. <edited>
Since it is idling, the turbos shouldn't be spinning all that fast, so there should NOT be much in the way of damage being done.
The 5 miles of driving should be enough to warm it up without the 10 minutes of idling first.
Grapeking is right, I was wrong, the manual does recommend driving it to warm it up due to something about pollution....
If it is really cold, and I mean below zero cold, I will let the car idle for 45 seconds,, maybe a minute before driving, but anything over 2 mintues is too long,,, IMHO.

I let mine warm up, but just enough to...
defrost the window (if needed) or to get the seat heaters going. Any more than that seems to be a waste of fuel, and more opportunity to have my car stolen.

Spoke w/Service manager at the Audi dealer (the only sane person I can deal with over there)
I explained the issue...
>> (background on troubleshooting) -- Following the posts regarding this issue,
1) I checked oil and it is low. So, I added it to top off properly.
2) No Engine Light.
3) No power loss / engine revs/ feels strong and limping.
4) Checked for any leaks and found none.
Service Mgr. suggested to let it warm up and Idle. He said it might be possible due to the frigid temperatures we are experiencing.
Now, I checked the oil again, made sure there is no Malfunction light. Loosened the Engine oil cap and started the engine... Monitoring now (engine has been running for approx. 20~30 mins) Oil temp is slowly coming back up.
Will keep you guys posted.

Jmacs-I believe the main reason is pollution avoidance-the cats need to heat up quickly to avoid
excessive output (I believe nitrous oxides are high in cold engines. Higher revs = more flow through the cats which in turn = faster cat warm-up, and therefore less pollution.
I personally just get in the cat, start it, let it idle 5 seconds or so, and go. I keep revs below 3k for the first couple of minutes.
FWIW, I put over 165K miles on my Saab 900 Turbo using this method, was still running strong when I sold it after 14 years.

That's what the service Mgr. said... (reg. starting & Idling)
he said that the turbos shouldn't have any issue.. However, I don't understand this problem.. Last time I parked the car, it was driven normally, and after highway driving (60-70mph), took the exit and drove for 1/4 or 1/2 mile to reach home. Waited a few seconds, turned off as normal.
Still don't understand why this would be the problem.
