Use the full 5,100 rpm power range. Avoid steady rpms. Avoid the use of cruise control. Frequent application of full throttle is recomended to help seat the rings. City driving is ideal for breaking in a TDI due to frequent stops and acceleration. Once you get to 5,000 miles change the oil and perform your first service per the manual
Simple I sampled about 30 TDI's over the course of 100,000 miles performing comrpression checks First with less than 500 mile on the odometer then at 5,000 and then every 10,000 miles there after until compression topped out at 550PSI. A random sampling of TDI's outside of this group also showed the same compression figures of 550PSI regardless of mileage when using 5w40 oils.
