Alpina EGS Flash for G31 - Type Code needed

[svenson]

No I‘m not sure about 5U20. Found it on some Japanese sites.

Many thanks for the code!
I will try it tomorrow.

Try this
G31 ALPINA D5s ECE LL (J1CB)

I couldnt find any information about 5U20 are you sure it right?

5U20 and J1CB are not correct typcodes for G3x cars. FP calculation will end in errors.
Alpina D5S is based on 530xd. You can use typecode JN51.
