To reach the bottom of this problem, you must seek out the support of a Mercedes unaffiliated specialist (ideally not the main dealer) who is knowledgeable in Star diagnostics. Fault codes ought to be published.

On the R231 model group on Facebook, anyone has written about taking the units open and correcting the dehydrated solders for 30 pounds worth of parts.

Would you please and please add his information?
In my view, three options exist.
1. Brand-new headlamp.

Updated control module(s) 2.
3. Upgraded beamer and module
