mb eqa JAMMED CONTACTOR
Hello, trying to understand the problem. MB EQA 250, after light crash(without deployed airbags), doesnt want to start. Ignition OK. HV and 12V battery are charged. The problem im having is "jammed negative contactor in the HV battery", fault code p0aa400. Trying to understand if the negative contactor is jammed on purpose, due the crash? And is it possible to repair the jammed contactor or it should be replaced? Thanks for the help!
