Default How to disable all bulb-out checks, for LED bulbs

Anyone know whether it's possible via VAGCOM or OBDEleven to disable the bulb-out feature. I've switched a lot of the bulbs to LEDs and used parallel resistors with success but the fog lights require such high power resistors I'm beginning to think there might be a better way.

Nope - the factory monitoring modes are expecting a current draw associated with a standard incandescent bulb. Your original fog lights were likely 55W bulbs, the LED likely 5-10W - the expected current draw is a lot more than what the LEDs consume, hence you will need the bigger heat rated resistors.
