Hey I hope the bmw community can help me out here, I installed the CSL yellow drls to my m340 and I have a right turn and left turn signal malfunction, I ordered mine from bayoptiks and they sent me the "revised" model and I got the same issue. Does anyone know what this might be??

Might be some coding for turn signal to fix issue with the new LEDs.
What are the fault codes?

[dilrajm340]

I am getting right front turn signal malfunction and left front turn signal malfunction

[TheNine90]

Can you read the fault code using diagnostic tool?

[dilrajm340]

i havent done that yet but do you think bimmerlink would work or i need a actual code reader? ive seen lots of people with g20s have this problem and nobody has figured out the fault

[TheNine90]

Bimmerlink should work
