If you fit LED bulbs that are 'canbus error-free' then you should not get the warning light.

However, finding the right LED's is not easy because a lot of them state error free but on Audi's they are not !

Turning off cold diagnosis will remove the warning light but the LED's won't work because the system still turns off the power to the bulbs if not enough current present.

Sorry but I can't comment on whether or not that cable is suitable for your car.

I assume you are talking about sidelights and you don't mention what car or what type of bulb it is !

I believe that the cold diagnosis is basically a start up check of the bulbs - and that you will still get a bulb failure if you turn it off when you turn the lights on.

Now it is a PITA if you want to fit LED replacements, but it is a fantastic warning system.

Cold diagnosis is exactly what it says, it checks the circuits when the bulbs arent in use hence Cold, as when used they're Hot
