Coding the E53 with NCS expert

these abbreviations are used in the trace files for the lights... most are 2 letters, some are 3. if there is a specific Left or Right, a letter L or R is added...

FL - HIGH BEAMS (L-LEFT; R-RIGHT)
NSW - FRONT FOG LIGHTS (L-LEFT; R-RIGHT)
AL - LOW BEAMS (L-LEFT; R-RIGHT)
BL - BRAKE LIGHTS (L-LEFT; R-RIGHT; M-MIDDLE)
BLK - TURN SIGNALS (LH-REAR LEFT; LV-FRONT LEFT; LZ-SIDE LEFT; RH-REAR RIGHT; RV-FRONT RIGHT; RZ-SIDE RIGHT)
KZL - LICENSE PLATE LIGHTS
NSL - REAR FOG LIGHTS (L-LEFT; R-RIGHT)
RFS - REVERSING LIGHTS (L-LEFT; R-RIGHT)
SL - PARKING LIGHTS (H-REAR; V-FRONT; LH-REAR LEFT; LHI-REAR LEFT; LV-FRONT LEFT; RH-REAR RIGHT; RHI-REAR RIGHT; RV-FRONT
RIGHT) - if i remember correctly, this is where the angel eyes should be looked at, SL_V, SL_RV and SL_V, SL_LV

the Dannish DRL were giving just the full intensity low beams, i suspect that the actual dannish DRL are half-intensity lowbeams, and since the HID can not produce half a beam or whatever, it just glows at full intensity.

one of the possible scenarios was (did not work out), to set up regular DRL with the high beams but set the intensity to 0%, and have the AEs just glow on their own - the plan did not work, as the angel eyes do NOT come on with the regular DRLs... unless there was another line to be activated in conjunction with this one...

another scenario would involve rewiring at the LCM level - actually switch the pins feeding to AEs with the corner lights... however, this accomplishes nothing, as you still need to turn the lights on and the goal is, to have the lights turn on with the engine, a la DRLs...

an extension of this scenario was to wire the rear fog lights pins to the AEs and have the AEs operate from the rear fog light switch S8, but this falls into the same category, the rear fog lights do not come on with engine, only with the rest of the lights, which is not what we are after...

is there an exterior light in these cars that comes on with the engine and it is NOT the highbeam?

and one more option, since these lights can be controled by a microcontroller via the iBus, stick a microcontroller that will do all of the above plus some other things, like unlocking the car on ignition off, folding mirrors on Park, etc, etc.... the problem is (or, the solution?), such a device already exists, it is called eLight module and is sold by a german company...

Thank Term. That helps a great deal. I have found some interesting settings within the LCM. Let's list some of the things I have done within the last 2 hours but, in my fit of new found excited, made no effort to document (like and idiot).

DRL
Low-Beams on (w & w/o AEs) - if your theory is true regarding setting the beam intensity, maybe we can set the low-beams intensity to 0 for no shine and the AE's will be left on.

Fun stuff

Fog lights as turn signals
AEs as turn signals
Both of the above as turn signals simultaneously
(I have to really pay attention here because, I actually like this. I think when you have these enabled, having the front signal lights enabled sets the parameters back to nicht-aktiv. Not sure yet.)

Rear-Brake lights as signals.

I have been reading countless other forums and have seen it said that the AEs can be enabled as DRLs so... on to more searching.
