Hey everyone,

I've spent over 2 weeks (ever since I received my order) trying to get my Morimoto Elite HID System 3Five (35w, can-bus, H7) working properly without ABS, ESP, Anti-lock brakes error lights.

I have been in contact with TheRetroFitSource, the distributors whom I ordered from, to find a solutions to this very frustrating issue. Their customer service is prompt and polite, but we have yet to find a solution.

I have searched all forums for solutions and applied them all without luck, well almost all.


What I've gathered through my research and applied:

-mounting the ballasts as far away from the ABS module as possible
-grounding the ballast (driver side only, should I do both sides?)
-grounding the can-bus harness (driver side only, should I do both sides?)
-splicing the brown wire on the headlight housing connector and grounding that (driver side)
-turning lights on before engine start
-from engine on, turning lights off before turning off engine

What does work for me is: turning ignition on, lights on, then both off and both on and off again, then finally on. The third time the dash will not show any errors where I can start the engine then, though there is some radio interference (which I don't mind).


So my questions are:

Does turning the ignition on and off 3 times rapidly to get the HID lights working have any negative effects on any other components which are turned on along with ignition? I am very concern this process may damage more expensive electronic components.

Secondly, are there any other possible solutions I can try to get these beautiful HIDs working error free?

Please shed some light into this issue as I would hate to resort to using the old dimmer halogens.

It's a 2004 Audi A4.


Thanks in advance.

Matt
