Look for a used one on Audifans or Quattroworld. There should be a glut of them as about 20 people have gone to VEMS and are looking to sell their ECU's.

Simple way to test; unplug the power cable to the HID kit and see if there is any changes in behavoir.

The bulb autocheck surgery was designed to counter the effects of
relaying high
watt euro headlamp installations. Relays were required for the high
current
involved in those halogen installations and always produced a bulb out
warning
because the current draw between headlamps could not be compared when
the
current had a different path through the relays.
This tells me that relaying the lights is guaranteed to produce a bulb
out warning,
not cure one. I agree that bulb out warnings are common if 10% of the
installs
having problems is defined as common. It is by no means a problem
with a majority
of HID installations. You have to remember that only the problems get
the press
here just like TV news coverage. When you are the one having
problems, the
absolute numbers don't really matter, other than finding the cause can
be more
difficult if it does not occur every time.
I don't know anything about the kit you installed, Peter, but the
newer kits with the
digital ballasts advertise lower starting current draw, and of course,
the steady-state
current is very low with either type. Since you were having some
headlight problems
before the install, I suspect the contacts in the stalk are causing
some of your issues,
but not all. If the autocheck is sensing a difference in resistance
between bulbs
sometimes, I would recheck the wiring and make sure all the
connections are good.
I believe you are destined for a stalk replacement soon even though
you have
reduced the current load.
You have not mentioned cleaning the headlight assembly or replacing
the glass
covers. I have seen a quantum leap in lighting on the road with these
two jobs
added to the HID install.

Unless it's an ignition driver chip issue, for which replacement chips are proprietry and NLA apparently.
