Headlight LED Dotmatric code - Hlep

I had a problem with my RHS headlight blowing the 32A fuse, on investigation I found the RHS headlight bottom ballast unit was causing the problem (A2229004505), water corrosion tracking to earth.
I ordered a new ballast unit and installed it, it's no longer tripping the 32 A fuse and main & high beam is now working; however, the headlight side indicator and low beam is still not working!
The OBD diagnostics shows headlight faults - U118B87 "communication with control unit - right headlamp range adjustment.

My suspicion is that either ;
one of the other two headlight ballast units (side &top) are also defective
or
the headlight needs reprograming
or
both

I would like to try reprogramming however the LED Dotmatric code is damaged and unable to scan, I can scan the smaller C code ok . I need this code to complete the programing, does anyone know any other work arounds or have any other suggestions? Access to Mercedes configuration VDOC data for my vehicle ?

Headlight part no A205 906 95 01
bar code 0 301 264 631 01 12 15 668 I believe the 01 12 15 is the date of manufacture ,

Car Vin code
WDD2050452R158592

Any help would be most appreciated

Regards
