I'm trying to enable the right foglight on a W166 ML350 2012 that I shipped from the USA to the UK.

WIS shows the wire on pin3 switching from left inner tail light to right inner tail light for RH fog light.

I already switched the wire but light still does not come on, I think its disabled in the SAM

I tried switching around the following values in the CBC file in vediamo, still no fog light.

Fragments Values
PLSM_HW_NSL_li freigegeben
PLSM_HW_NSL_re nicht freigegeben

I've attached my sam coding file, would love any pointers to solve this.

Am happy to pay if someone can do it via teamviewer.

Have you changed the right inner tail light to a LHD version? I drive a 2015 and the right inner tail light has the reflector, but no LEDs. Without changing the hardware, no wiring or coding change will illuminate the right foglight. Shine a flashlight up in the foglight and compare left to right, I am betting there is a difference.

Thanks JRSmith, you hit the nail on the head.

I was so engrossed making sure the wiring was correct, checking voltage etc, I did not think to check the light itself

The right light is indeed missing the required LED's. Will order a UK replacement
