I've read threads that talk about adding external resistors, using higher wattage bulbs, and coding out the bulb checks when adding LED turn signals. I haven't found a thread with a solution that works 100%.

In the FRM module there are two entries, LED_BLINKER_VORNE and LED_BLINKER_HINTEN, for front and rear LED blinkers.

Has anyone tried these to see if they solve LED turn signal hyperflash without adding an external resistor? I was hoping these entries would let the FRM module handle LED bulbs ok.

 

Have you tried CANbus approved bulbs?

 

From the threads, CANBus bulbs take care of the cold/warm check errors but don't have enough resistance to avoid hyperflashing. I have seen LED bulbs claiming to be CANBus and consuming 25W like an incandescent. They *should* work.

But, as many people seem to have had issues, I'm curious if anyone solved their problems via the LED_BLINKER keywords before I start purchasing bulbs. Be nice to have a confirmed backup plan.
