No sure - if the globe blows I don't think you will get a warning, If the ballast fail you might get a warning. The LCM test for continuity so even if the ballast fails but still manages to consume some power and create a closed circuit the LCM will be happy. Interesting to see results of failure points. Remember that with factory bixexons the LCM doesn’t test the dipped beam circuit at all.
I’m not running the later BETA version of navcoder so I didn’t see the option of cold testing on the trailer – I’ll upgrade and have a look but I still need to find a trailer to test, another point to consider is that not all versions of the BMW LCM have all of the options that navcoder tries to do.
