TriggerFish Posted October 11, 2014 Report Share Posted October 11, 2014 (edited) Hi all, I've got myself a sw4 LCM (for the triple blink indicators) from a 2006 built coupe. I've got this into my car, and the lights are working OK in that the right bulbs come on for the right functions. Now, I've seen one single post on an American forum which says that the facelift coupe LCMs can't control the levelling functions of the headlights are they have separate modules to do this. I can't find anything else to corroborate this, but I do know that my headlights don't move, except for the POST. The car they came from didn't have xenons, and the trace implies that it's using non-dynamic levelling (but my NCS is struggling to write to the LCM due to the old daten files). Is this expected behaviour? Can they really not level the headlights on their own? If not, I'm guessing the modules can't be fitted to the saloon, in which, the LCM is of no use to me I guess? Cheers, Joe Edit - this is where I saw it - http://forums.bimmerforums.com/forum/showthread.php?1700223-NCS-and-E46-LSZ&p=22549660#post22549660 http://forums.bimmerforums.com/forum/showthread.php?1700223-NCS-and-E46-LSZ&p=22550403#post22550403 His posts are usually accurate Edited October 11, 2014 by TriggerFish Link to comment Share on other sites More sharing options...
TriggerFish Posted October 11, 2014 Author Report Share Posted October 11, 2014 I took the LCMs apart to check for that circuitry mentioned. Apart from one extra piece next to the ribbon on the old sw3.11 one, the hardware looks the same (so I assume the levelling stuff is present?) sw4.0 on the left sw4.0 sw3.11 Link to comment Share on other sites More sharing options...
CharlE46 Posted October 12, 2014 Report Share Posted October 12, 2014 (edited) Interesting read Joe, I bought an LCM with SW4.0 for triple blink aswell an age ago (not fitted yet as it's still coded for rear LED's) but luckily mine was from an 06 M3 which according to that linked thread should be ok for leveling. I've got an Xenon SW3.01, non Xenon SW3.6 and an Xenon SW4.0 sat in front of me in bits now and they're all slightly different, not sure how easy it is to determine if the hardware is there or not. Will watch this thread with interest sw3.01 - sw3.6 - sw4.0 SW3.01 xenon SW3.6 non xenon SW4.0 xenon Edited October 12, 2014 by CharlE46 TriggerFish 1 Link to comment Share on other sites More sharing options...
TriggerFish Posted October 12, 2014 Author Report Share Posted October 12, 2014 There's an LCM variance bit you can change to set it up for saloons - its set to wert2 by default, putting it to wert1 will tell the LCM its in a saloon Cheers for the photos, I'll do some comparison when I'm not on my phone CharlE46 1 Link to comment Share on other sites More sharing options...
bungers Posted October 12, 2014 Report Share Posted October 12, 2014 Joe, so it's clear in my head (I'm a lot hungover today :-/), a) your car is a saloon both your car & the donor car had halogens c) you're trying to get the adjuster dial to control your retrofitted xenon height? The only extra module I'm aware of for anything to do with headlights is the control module for horizontal movement in cars with adaptive xenons.

TriggerFish Posted October 12, 2014 Author Report Share Posted October 12, 2014 Correct Paul - mine's a facelifted saloon, both had halogens and yes, I'm trying to get the LCM to adjust the standard levelling for saloon halogens (while I retrofitted projectors, I kept the original manual levelling - I've not touched that side of things) Link to comment Share on other sites More sharing options...
TriggerFish Posted October 12, 2014 Author Report Share Posted October 12, 2014 And this is the variant bit I mentioned: VARIANTE_LSZ LIGHT SWITCH (LSZ) VARIANT wert_01 value 01 LIM+(PU01,HKL_FL) * wert_02 value 02 TOUR,COUP,CABR,LIM+!PU01+!HKL_FL wert_03 value 03 COMP+!PU01 wert_04 value 04 COMP+PU01 And http://e46.bmwklub.cz/download/file.php?id=39021&sid=a10e25c329f8b0e5c2fa9c0e0a1dd8a6&mode=view confirms that the pin outs for the rear lights are the same on everything except the saloon.

CharlE46 Posted October 12, 2014 Report Share Posted October 12, 2014 Cheers for that link, it explains why my fogs came on instead of the normal lights when switched on, will change the value Link to comment Share on other sites More sharing options...
bungers Posted October 12, 2014 Report Share Posted October 12, 2014 Correct Paul - mine's a facelifted saloon, both had halogens and yes, I'm trying to get the LCM to adjust the standard levelling for saloon halogens (while I retrofitted projectors, I kept the original manual levelling - I've not touched that side of things) Cool, well my next door neighbour has a facelift coupé which has had factory xenons retrofitted but kept the standard LCM & I coded the manual height control back in. Did you change your FA when you were having issues with the xenons as adding 522 disables the dial as it presumes you have the level sensors? Speaking of which, these feed the LCM with data which in turn controls the height rather than the sensors directly controlling the lights. Did your old LCM dial work?

TriggerFish Posted October 12, 2014 Author Report Share Posted October 12, 2014 Ah, yes! I think I did add xenons to the FA, although the dial works fine on the old LCM (which I've reverted back to for now). I'll try removing that from the FA and syncing it back to the LCM. This is all being made harder by an inability to interact properly with the LCM via NCS as I can't write to it properly (although I can read, and use PA soft on it). I'll give it a go during the week as I've drained the battery while trying yesterday and can't risk draining it again today as I'm the last to leave in the mornings, so can't jump start it again.

bungers Posted October 12, 2014 Report Share Posted October 12, 2014 Ok, there's a setting which I'll dig out when I'm back on the laptop which needs to be enabled to allow the dial to work. Did you change the FA on the new LCM? I had some NCS issues like that a couple of weeks ago and I sorted it by clearing out all of the files in the 'work' folder & then restarted the EDIABAS.

TriggerFish Posted October 12, 2014 Author Report Share Posted October 12, 2014 Thanks. Yeah, I got PA Soft to sync the FA between the dash and the new LCM, including the erroneous xenon code. Ah, mine is partly down to old daten files - it didn't have anything for c36/c37, and now it does, so it can read, but I think I'm missing a file as I can't write (NCS v3.0.1) Link to comment Share on other sites More sharing options...
bungers Posted October 14, 2014 Report Share Posted October 14, 2014 Hey Joe, sorry for the delay. If 522 is added to the FA, you need to reactivate POTI_LWR_INVERS as this is disabled on xenon coded LCMs. This will give you manual headlight height control via the dial on the LCM. Send me your LSZ trace if you're still having issues and I'll see if there's anything I can spot. TriggerFish 1 Link to comment Share on other sites More sharing options...
