There are definitely differences. The 190E 2.3 #3 injector line is part number 201 070 47 32. The on-line EPC shows the W123 230TE which you can compare with the US market 190E 2.3 at least for engine parts since they both use variants of the M102. Mind that the US engine went through a couple of updates the life of the 190E.

How does your 230TE manage to have a 2.2 liter engine?
