Bulb out warning after HID installation

So after installing a custom wiring kit for my new HID lights in my '02
Audi A4 the headlight out warnings come on for both right and left.  I
understand this is the Audi sensing that there is less than 1amp being
used on the circuit now (due to the new relay) instead of the amount of
amperage used by an actual headlight so it's triggering the warning.

Anyone know of a fix?

Contact the provider of the custom wiring kit?

You have to lobotomize the bulb out warning circuit. On the older C4 cars,
this is fairly easily done. On your car I don't know if you can...

Do a search on audiworld.com.

Or get some black plastic tape :)

Thei happened on the T44s when the lights were converted to relays. The fix was
to pull the headlight relay and bend over a pin that was labled 'K'. That pin
was the output to indicate an error. I am not aware if this would apply to the A4.

It has a whole section on lights.

Thanks for the link..   I've spent about 3 days searching on google
before posting here. =)  I emailed those folks, but I'm really looking
for someone who might know how to disable the sensor in an 02 audi, or
build something to kill the warning.  I built the Relay myself, so I'm
fairly adept at plugging stuff in and such ;)
