[2009] [SOLVED] Bi-Xenon [HID] randomly shut off individually. Maybe from bumps
[ISSUE SOLVED. SEE LATEST POST]
09 Rabbit Factory Stock with HID's & Fog Lights
Just bought it in May 2015.
Issue
Either the driver or passage side applies to the following:
It seems as though any kind of slight vibration tends to cause the HID to go out.
Sometimes a few taps to the unit will set it off. However, other times driving over a large pothole causes no issue.
It is very random.
One thing to note however, only one side will go out. Not both. This is random as well.
Sometimes the passenger side, sometimes the drivers side. Again, never both.
The headlight dash icon with the exclamation mark comes up on the dash when this happens indicating one of the bulbs is out.
Other things to note
My daytime running lights never turn on.
My fog lights works as they are supposed too.
What I've tried so far
I've tried both OEM HID bulbs and aftermarket HID's.
I've checked for any loose connections to the HID igniter or other cables to the headlight assembly. All are fine. None seem to be loose or get loose.
I've had a mechanic check to see for any loose grounds and running a Vagcom Diagnosis. Nothing turned up.
The mechanic did some other minor electrical tests that I imagine where mostly wiring within the headlight assembly or grounds to which all seemed to be normal.
Potential Culprits
After lots of searching I have found someone with a similar issue.
They said the problem could be with the ballast which from what I understand is usually described as the HID Control Module.
I'm not to sure if this controls all the headlights or just the HID's.
Does anyone know?
This is a very pricey part to replace. Close to the 500$ mark.
Its strange though that if this is in fact the problem, that both are now broken.
Next Steps
Next thing for me to start with is replacing the daytime bulbs. If that fixes the daytime lights issue, then thats great.
Although I imagine it will not solve the HID turning off issue. But stranger things happen I suppose.
I'm hoping someone can tell me if the HID's always come. I can't recall if the HID's always came on with the daytime lights or they only come on when set by the knob in the car.
If anyone has any thoughts, they would be very much appreciated.
This is tricky to diagnose.
