This article will show you how to activate the welcome light on the Mercedes-Benz rearview mirror (code ZGW module) through Xentry and Vediamo.

First we need to adjust some settings in Mercedes-Benz:

Turn on Surround lighting on menu.

Now, turn signal light turns on but welcoming light not when we unlock the

So, what we gonna do is code on PC so that they both would light as we unlock it. 

The device that connects Mercedes-Benz to PC could be VXDIAG VCX SE, MB SD C4 Plus, Super MB Pro M6...Different coverage, you can choose by your needs.

Note: Only Vediamo can code the module called ZGW, Xentry and DAS don't support it.

The first thing is that we need to figure out a CBF file for the ZGW unit.

So, how to find the CBF file we need for ZGW module?

Here we'll show you through Xentry Diagnosis.

Select our model - E(212)>>Control Unit>>Body>>ZGW

Encoding>>Configuration>>Encoding>>Displaying encoding data

Here "Code 500 (Folding outer mirror) - not available”

Go to Topology, select ZGW's code - N93.

Here we know we need the CBF file (CGW231) for ZGW.

Now we need to encode it through Vediamo.

Open up Vediamo Start Center.

Go to "Ecoute".

On "System Selection", 

Check "Systems based on DIOGENES data (.cbf files)" and select "CGW231" CBF file.

Go to "Variant Coding", select

VCD_02_global_variant_coding>>Einstiegsleuchten>>available>>ЕCU-Coding

Select "Continue" and "Close".

Unfold "CGW231" and "Function".

Click on "FN_HardReset".

Finally, disconnect ECU CGW231 and exit. 

Test: when we unlock the car, the turn signal light flashes, and the welcoming light on the bottom is on. So cool. 

Alright, you can also add lights to your Mercedes.

Hope this could help!
