FRM Question!

I'm converting from adaptive pre-LCI to adaptive LCI Xenons this next week. Question: If I swap the from FRM to FRM3 right now without any coding, will my current headlights still work?

Head lights will work. You will have an error message

Unless you are upgrading to gain welcome lighting and AE as DRL, there is no need to upgrade for pre-LCI to LCI adaptive xenon headlight conversion.

If you do not upgrade the FRM, the 3 LEDs in the corner of the LCI housings will not work. However, it can easily be jumped to supply power to the LEDs. Most people actually don't like them anyway and leave them off.

Only other thing to do is code off bulb check for front turn signals.

Thanks for the help. Yes to the AE DRL's. I'll also be converting to LCI tails which appear to also require FRM3 (?).

I hardwired my AE to my cigg lighter since it's switched with ignition. Then added a switch to control the AE if so needed.

You don't even need to pass any wiring through the firewall.

The FRM sits right by the OBDII port. I found the pinouts for the AE and used a quicktap to jump both AE circuits with the cigg lighter.

LCI taillight do not require FRM3.

I have coded LCI taillights multiple times for FRM1 and FRM2 cars. You need to disable the turn signals, brake lights, and brake force display build checks and works as it should.

Also, some FRM1 modules have AE as DRL and WL (welcome lighting) as an option. You can try pushing the latest software to your FRM to gain AE as DRL and WL.

I know many will say this is not true. I used to think so as well until I coded a 10/06 build E92 335i with FRM1/FRMFA in it and it had AE as DRL and WL.

Meant to ask previously, what is needed so that the led front and rear turn signals no longer blink quickly?

The swap is complete, and everything coded well on the FRM3. Except that now we're getting this 'strobing/flickering' from only the front turn signals when they are used. No matter what we do, we're unable to get them to work properly when the engine is turned on. Have either of you experienced this or have any recommendations? Bad FRM?

Here's a video I took of the issue:

If you have LED turn signals, you need to add a resistor to them.

Do you speak from experience or is it just an educated guess? Just curious as they work fine when the car is in ACC mode, it's only when the engine is on that they strobe/flicker. And it's not the usually "quick blinking" that a resistor is typically used for when going from a filament type bulb to an LED. It's very odd.

I have installed them on my 335i for my reverse lights.

However, it's my understanding that an FRM 3 is supposed to allow LED lights to function normally.

I'm wondering if it's just a bad FRM3. With the stock FRM1 the lights blinked faster (i.e.: something a resistor could fix), but there was no flickering or strobing

I think BMW had a recall on FRM 3 modules about 12-3 months ago. I know this because I had to replace the one on my wife's x5 last winter. It's was really difficult to find an FRM 3 module because of this. I finally tracked one down for really cheap at a BMW dealer in NJ. I think I might have paid $300.00 shipping included. Had it in 3 days time too.

You code the warm and cold bulb checks off to prevent the flickering/hyper flashing.

Have done it on hundreds of cars.

Using a resistor defeats the purpose of using low powered LEDs. The resistor uses up the excess current to prevent the bulb out warning and it is wasted as heat, thus the large size/heatsinking of the resistor.
