G30 headlights from US to ECE

[iv_D]

HI all,

I imported a G30 540i from the US and have changed the headlights with the EU version. 
I need to code the typschlussel in the FA to the ECE version but can't find the correct number. 
At the moment the value is JE53, I have tried with 51 and 52 and I get an error.

Does someone know what the value should be?

Thanks in advance!
