Brian The critical factor for automotive electronics is whether or not they are 'immunity related'. Any equipment that relates to control of the vehicle in any way; e.g. engine management, braking system, steering, evn automatic screen wiper control, is 'immunity related'. If the equipment that the dc-dc converter supplies is 'convenience' equipment such as sat-nav, mobile phone, DVD player, or similar, then it is not 'immunity related'.
Typically, immunity-related equipment requires a much more comprehensive test regime (including immunity tests) and would require 'e' marking. Other equipment does not require the radiated immunity tests (although should include conducted transient tests)and can just be CE marked. This is a change from the original automotive EMC Directive (95/54/EC) which required 'e' marking on everything. 2004/104/EC corrected this nonsense. CE marking would be to the EMC Directive, 2004/108/EC, not to 2004/104/EC. The Low Voltage Directive does not apply, as the supply voltage is outside the range of that Directive, unless the equipment is subject to the R&TTE Directive, which has no lower voltage limitation, but compliance would be to the R&TTE Directive, which applies the requirements of the LVD, not to the LVD itself.

The directives 2007/28/EC, 2004/104/EC, and 95/28/EC would seem to apply. But I am not certain about particular requirements for an 'aftermarket' component, and the required marks ('e' vs 'CE') for import. Do the EMC or Low Voltage directives apply ?
