Replaced 996 Headlight Bulb now battery is draining

Recommended Posts

First time poster here and great forum.  I replaced the OSRAM bulb in the headlight on my 2002 996 c4 cab.  It was quite easy to remove the assembly replace the bulb and reinstall.  The problem I am having now is the battery is draining,  Is it possible the assembly is not seated correctly, the wire on the H9 OSRAM bulb is nicked or maybe one of the one of the pins are bent on the rear connector in the assembly?  Any advice would be appreciated.  Thank you

I've had my woes with installing the headlight assemblies.  On the left side I broke the plastic plug support the right side I couldn't get the directional light to work all the time.  Finally figured out the headlight assembly wasn't seating in the plug properly, bought a new tray and that took care of the problem.  Mating the assembly with the plug always seems like a vague proposition too me, you're relying on a lot of plastic for alignment. 


I think you've answered your own question, I would remove the headlight assembly and see if that stops the battery drain.  Like you said check the plug for bent pins, be sure you haven't broken the plastic plug support.  On my 2003 C4 it's a rather fragile hoop that retains the plug.  If you didn't have a problem before and now you do it must be some problem with the plug?


Let us know what you find...


And congratulations on posting on the forum...
