Mercedes Control Unit E1n9 Headlight

[1spat]

Thank you for your information, it's little bit strange because the ECU is not aftermarket.
I have to order another one and check it again and I will share it here.

The ECU it's a brand new but I'm not sure it is Aftermarket or not

You know whether you ordered it from the dealer or not. Clearly has a Xenus sticker on it.
