The 1.9 TDIs are 79,5mm bore X 95,5mm stroke (as are the 1.9 IDIs) Compression ratio on the 1.9 distributor pump TDIs is 19,5:1, and on the PD it is 19:1
The V10 TDI is 81,0mm bore X 95,5 mm stroke, and I believe the CR is 18:1, but I'm not sure.
the 2L TDI is 81,0mm bore X 95,5mm stroke, with 18.5:1 compression ratio .
The 1.4 TDI (3 cylinder) is also 79,5x95,5 with a 19,5:1 CR.
You should also be able to glean specs on the current models from www.volkswagen.de - correct me if any of the above is wrong... :)
HTH,
Drew
PS - don't apologize for your english - its obviously quite acceptable! :)

Oh, Ok. Forgot about the grandmama of all TDI's.
The 2.5L 5 Cylinder TDI had an 81mm bore and 95.5mm stroke for 2.46 displacement.
There's a 2.5L V6 TDI as well, but I can't find any info about it.
