Ready to race!
Is there an engine break in? If so what is it. I have read a lot about it in general but I figured the VW people like you would know the best... I have a brand new 2010 GTI

Keep rpms below 4,000. Avoid steady rpms. Frequent firm (75%) application of power is strongly recommended up to a maximum engine rpm of 4,000. Avoid the use of cruise control so that you naturally fluctuate the power with your foot.
DO NOT CHANGE THE ENGINE OIL UNTIL 10,000 MILES!
1,000-5,000 miles
Use the full 7,000 rpm power range. THIS DOES NOT MEAN DRIVE AROUND AT 7000 RPM! This DOES mean to find the rpm range where your cars best power resides. Most owners will find that the best engine operating range to be between 3000rpm and 5000 rpm for the purpose of acceleration. At all costs avoid using full throttle below 3000 rpm the ECU will attempt to prevent you from applying full power in this range, work with it and don't request it with your foot.
Continue to avoid steady rpms and avoid the use of cruise control. occasional application of full throttle (100%) is recommended to help seat the rings. City driving is ideal for breaking in due to frequent stops and acceleration. DO NOT CHANGE THE ENGINE OIL UNTIL 10,000 MILES!
5,000-10,000 miles
Use of the cruise control is ok at this point since most of the initial break in has occurred. Continue to use occasional full throttle accelerations to continue to seat the rings. You will notice the engine become slightly louder during this phase due to less friction from the engine breaking in (normal for a diesel to become louder under lighter loads). If your going on a long drive and you are using the cruise, every so often step on the peddle to accelerate up about 20 mph then coast back down to your preset speed.
Your first oil change is due at 10,000 miles DO NOT change it early! Oil analysis supports 10,000 miles as being realistic for a first change interval. Wear metals will remain at safe levels during this entire first interval thanks to the initial run-in and flush at the factory before the engine was installed in your car.
10,000-60,000
This is when the rest of the break in occurs. [**TDI info-- The engine from the factory will check out with about 475psi of compression pressure out of the crate. It will take at least 60,000 miles to reach the peak pressure of 510 psi. For the most part once you get to 10,000 miles your compression will be around 490 psi meaning that most of the break in has occurred.]
60,000+ - the life of the motor
The owners have followed the advice above and do not have any oil consumption issues. This also means that with the higher pressure the engine is more efficient returning optimal fuel economy and reduced smoke output.

Translated for a gas powered GTI-
Rules that apply for the life of the car
-When the engine is cold (below the first 3 white marks at the base of the temp gage) rev the engine to at least 3,800 rpms.
-When the engine is warmed up (above the first three white marks) Rev the engine to no less than 4,000 rpms.
The reason for this is to keep the turbo on boost, clear the VNT guide vanes and apply firm pressure to the rings for optimal sealing against blow-by gasses. The rings need the boost to seal since its a turbo charged engine, babying the engine is detrimental and will lead to issues with compression if done so for very long.
-Keep rpms as close to 3000 rpm as possible when driving at a steady speed.
-Allow the DSG or automatic transmission to determine the optimal gear and engine rpm. It knows better than you... Provided you have it trained to be biased to the sport mode the engines shift points will occur at the ideal ranges.

the basic principals are very similar, a Gas motor has lower compression but not running it at a steady state and not wailing on the motor before it is warmed up properly goes for any motor.Don't attempt a 'translation' - diesel engines have rather different tolerences and fundamentals than a gas engine. Read the manual.
The 10k first oil change makes me kinda cringe as well.. I wonder what a good/safe compromise would be. And if the dealer would change it earlier than 10k by request? Say 7 or 8k
