Need help coding led foglights

marmit2017 · 10-10-2018, 11:40 PM

I've got an f30 that I installed oem led foglights in that seem to need to be coded. I coded off bulb check so they don't flicker on start up. However after a minute or so they start flickering. I've got all the software (e-sys and more) and cables. I'd really appreciate the help

You should better delete the 520 from your VO and add the 5A1.
Then code the FEM with the modified VO and everything should be OK.

Flicker on start up is from the cold check. Flicker after that is from the warm check. You have to code both to not active. Strobing when they're on is from 'is LED' not being active.

This is the correct solution, as I just did this upgrade myself last week. You may have to also update the date code (Zeitkriterium). 0715 should work.
