the previous generation TDIs were considered run in properly at 80k, this was measured by someone on TDI Club who rated cylinder compression i think, he then found it peaked at about 80k then stayed steady till 250k plus afterwhich the drop off was very slow.
I would imagine that the same applies for the new 2.0 tdi which your probably referring it. It doesnt matter what platform the engine is in (Golf or leon) the engines are essentially the same.
