Nonsense...
When the car was new, she start perfect, when is cold, with this software!
There is mechanical problem...

[Min2xx]

Compression tested in Audi dialer, audi dialer do not find any problem, can't repair ... I not find any problem too, timing is about 0 ( tolerance +-5 ) !

So, what you propose to be done?
More fuel, extended pre-glow?

[teamtuner]

Need more fuel on cold start, engine want to start, seems need little more fuel

[bobolin4o]

Look, i ask you to define "cold start"!
Here, where i am now, the "cold start" mean 25-30 degrees of coolant...
Be more specific.

[Min2xx]

Yes, more fuel at 20-30 degrees

[bobolin4o]

Test this...

[CustomCars]

Try my thing
If no work, search more in mechanical, check airfilter, fuelfilter, close EGR

[bobolin4o]

What happened?
Is there joy or not?

[Min2xx]
