Great pictures - with some of the errors, try moving the steering wheel all the way to the right, then all the way to the left. That should help clear the BRAKE and 4x4 errors.

Don't ever run the car without the modules - not a good idea Always disconnect the battery anytime you unplug any module.

That 4.6is is awesome - loved the E53, still have mine, 53k on her now. I only have a 4.4i but I love those naturally aspirated motors, the E53 just feels very connected to the road.

Great mods BTW - and great pictures.

Having gone through an FRM replacement which resulted in reversed power window operation, I'll tell you that it ultimately required a special coding session with BMW-NA at the helm to remedy it. They had my X5 hooked up to a special dedicated laptop and the session apparently required a lot of bandwith. The dealer's IT guy was freaking out. No one could explain why this was level of programming was required but the normal coding that they can do at the dealer was not sufficient to fix this issue.

Josh, you had the dealer code the FRM for LED headlights?

No, I was just replacing my FRM because it crashed while I was trying to code it for a few additional options. I believe battery voltage went too low during the actual writing process.

Prior to the replacement barely anything worked correctly or was in some sort of default operating mode. Then once it was replaced and coded by the dealer, most everything worked but the FRM still was not communicating with the dealer computer and power window operation was reversed left to right. They were puzzled.

They contacted some tech at BMW-NA, set up this special coding session, hooked up a laptop running some program and BMW-NA took over from there. Everything worked from that point and they could communicate with the FRM just fine.

Just mentioning it because one of your symptoms is similar. What it exactly means, I don't know and oddly enough, neither does BMW.

I appreciate the positive comments guys... Chris, thanks for the steering wheel tip!

I finished the LED headlight install on Friday (except for coding). FRM3 Module reconnected and the car has been put back together except for the bumpers and sideskirts, which are being refinished.

So far this is what is happening;
The left side halo rings, low and high beams work, but no turn signals or amber running lights.
The right side halo rings, low beams, turn signals and running lights work, but no high beams.
I also noticed that my window buttons on the driver's door are now reversed (left switches control right side windows and vise-versa)?

I'm wondering what else has changed with the new FRM3 module that will have to be corrected?

You did the correct wiring for your M, right? There are two scenarios in the retrofit instructions - with adaptive lights and without. I believe all US spec cars HAVE option code SA524.

I just went back and read the retrofit LED headlight instructions once again to be sure: SA 524 is Adaptive Direction Headlights (not fog lights), so mine does have SA 524.
