The only advice I have is make sure you drive your car for a significant enough period of time so that it reaches operating temperature.
Short drives in our cold climate/weather will lead to condensation buildup and wreak havoc on the engine...

If only takes 5-6 sec at -24C, I would consider normal. It take a lot of energy to start any engine in a cold like that. The engine needs twice the energy it going ajd the battery only produces half as much as it can so, it's normal for any engine to be a little slow cranking in a cold like that. I don't think there is anything wrong with your plugs or coils.
I am not suggesting this... but when I was Ice Racing, the car would sit out in open cold for a whole week... and we are talking a 250,000km+ piece of junk... We would remove the battery and store it indoors, and also remove the oil and keep it room temperature. We would show up, pour in the oil, hook up the battery, and the car would start without serious drama. If we didn't do this, we couldn't get it to start in the cold. Why is this important to your thread? Because it discusses how battery and oil temperature are related to cold starts... its crucial!
FYI... below -20, my Benz takes a bit longer to wake up also... it's normal. Drive it and enjoy it...

If you think your A4 was loud when it fired up, you should hear a diesel (even just a 1.9L 4cylinder) fire up in sub -20C weather. Sounds like a bunch of angy monkies with sledgehammers under the hood. 
Tomorrow morning will be a good test for my two diesels. Changed the glow pugs in the wife's car yesterday afternoon as two of them were not working.

I'm not sure if this will be helpful. My Z has difficulty starting under +10C and below about +4C won't start at all....twin side draft SU carbs. However, plug in the block heater for an hour or 2 and it starts instantly in any temperature even after 5 months in storage. Wonder if there is a block heater available for Porsches?
