Star Diagnostics required for Bi-xenon ballast swap on W211?
I have a malfunctioning Bi-xenon on my 2008 E300 (W211) that may require replacing the ballast. I've found one seller on Ebay offering a compatible Hella: 5DC 009 060-00 unit but with the following disclaimer in the body of the ad:
For putting the ballast into service it is necessary to install software and afterwards carry out coding by an appropriate diagnostic tester.
In this case, please contact the relevant Official dealer.
Note:
Experience has shown that in most cases you can avoid reprogramming if you swap both sides at the same time.
