You should read what I said before.
There is no break in. There even is no test run besides the dry run I mentioned.
The first real run with fuel is when the finished car leaves the production line.
And btw, at least all the European market EA888 (GTI & R) engines are made
at the Audi plant in Györ/Hungary.
Sorry - i thought i should chime in here seeing as just earlier this year i did a tour of the Wolfsburg plant whilst on holiday.
Each and every car after being assembled is put onto a dyno to check running and electricals. During this, the technician absolutely rings the engine, redlining it several times and going down through the gears with heavy engine breaking straight off the production line. I asked the tour guide and he said the car will end up with somewhere between 10 - 15km on the odometer following the testing.
Considering the main idea behind "breaking in" an engine is to seal the piston rings against the cylinder bores and wear them smooth, the 10 - 15km of hard running each car gets will honestly do 90% of the job. So the engines are pretty much broken in from factory. They don't however do an oil change after this - just stick them straight onto the train.
So, sorry, but you're just completely wrong.
For anyone interesting, you should definitely do the tour of the plant if you find yourself in Germany. It takes about 2 hours and is super interesting (and free!).
