Any way to disable Cold Diagnostics for LED retros?

[agentsmith988]

I threw in an entire set of LEDs (brakes, signals, sidemarkers, etc) and I'm not getting bulb-out errors. However, I'm getting a very cop car-esque flash sequence every time I turn the car on as it goes through the cold diagnostic sequence. I know that with newer VAG products long-coding can be used to disable the "Cold Diagnostic" feature that runs when the car is turned on. Is anyone familiar with any way to disable it in the B6?

I tried adding a resistor to one of the sidemarkers without any effect. Does anyone know of any coding/wiring change we can do to ditch the diagnostic sequence?

I get the same thing. I just deal with it. Only happens during startup. Not worried about it.

I've been trying to figure out if the pulses during startup are a full 12 volts but I don't think my multimeter is fast enough. I'm wondering if something like a capacitor could be used to take the pulses like an accumulator/shock-absorber.

If the pulses were less than 12v, maybe something could be rigged to step the voltage down a bit. The LEDs I have only need 9v to operate so if the overall voltage was stepped down, maybe the flashes wouldn't occur.

Any electrical engineers out there?

The LED high beams I have do the same behavior. It's annoying
