LED rear turn signals (hyper flash)

Hey guys,

I recently installed some LEDs for my rear turn signals in my 328i. When I first (after start up) activate the turn signal, it hyper flashes a couple times then it goes back to normal flashing and on the dash, the warning bulb light comes on at first, then it goes away. it only happens for the first time like on start up. After that, when the turn signal is activated again, it works fine. Any help?? Do you think coding will do the trick?

So I have this problem on my 210 335i, and from what I gathered it has to do with a non-cooperative/potentially bad diode somewhere in the light. But i really just have accepted it because the only way for me to fix it, is to buy a whole new light.

Did you swap in new assemblies or is this just an LED bulb in a standard socket?

It's an LED in a standard socket. But I have resolved the issue. You simply code out the bulb checks for the rear.

Glad you got it figured out for your car. LEDs in a standard socket do that. Had in happen in my other vehicle.
