Where'd you get your kit from?

any links?

i've dealt with it many times in the past, the solution is you need TWO error cancelers on each side..after that it will work fine..there is nothing else you can do to make this work.

good day.

Hi Got same issue with my friends new Volkswagen I use both of them and it worked

[Boss777]

Used two capasitors on one side and it worked for 55w balast so if you want or will do in the future tip use two if one does not work on newer 09 bmw one works but older 07 you need two

Why don't you just code the fog lights and turn PWM off? Then you don't have to worry/deal with any of these BS error cancelerrs or load resistors.

The reason why the the HIDs flicker/turn off is due to PWM. PWM is used to lower voltage for the original halogen bulbs. It's intended to extend bulb life as their current draw and output is proportional to voltage input.

HID ballasts typically require at least 8v to operate correctly. PWM in my car drops fog lights and angel eyes fixtures down to 7.7v with the motor running.

With the motor off, PWM is not utilized. That's why people don't have issues with the engine off.....the car is using battery voltage. PWM is also used to regulate alternator voltage. Alternator voltage can be up to 15v stable when it is engaged and PWM is used extensively throughout the vehicle to bring voltage back down.

Can you explain how? I would like to know how to code off the PWN for front fog lights!
