Multi-beam in Canada?
Thanks!
Thanks!
Until something malfunctions on the headlights and MB refuses to fix it under warranty because they blame the non-factory coding for the problem. As to the second question I have, I don't want to purchase it only to have it nullified because of a dealer update to the system. They are both reasonable questions.
Thanks!
Note that any continuous dynamic high/low beam concept for all manufactures will be DOT approved soon. So, I would just install it and if dealer updates, simply load it again. MOT inspection will never notice low beam cut off difference, it is a non-issue.

There are plenty of very competent industrial control programmers with a side hobby of automotive firmware, never mind the thousands of individuals actually employed writing automotive control software and firmware integrations. This may seem black magic, but it is not. All that is being done is one version of factory written firmware is being substituted for a different version of factory firmware. Simply a sophisticated Cut and Paste exercise. Either way it is just a bunch of 1's and 0's doing their job. Nothing is risk free, but what we are doing here is pretty close. I would put the risk somewhere between getting hit by a meteorite and one of my Soufflés collapsing, as in not yet! OK?

the “unlock” provided by Valdimir does not enable the blue welcoming DRL’s
i did ask him about this as so many people are asking about it. He replied with: “I did not do the White-> blue codings but we can try later especially in this feature”
so maybe coming soon, or later. . .
but we can try later on especially this feature

Very good explanation. Thank you Mike_S.
As I have already pointed out, owners who never travel at night outside their well lit city roads probably will not benefit from this modification much less the actual factory EU Multibeam option. What is does do on semi-dark road stretches and in unlit rural roads is, however, a revelation. Anyone who does travel outside built-up, well lit areas should modify the US and Canada Multibeam LED units to their full function with Vladimir's firmware mod.
Driving in the city there are subtile differences, the principle one is the European high right hand cutoff that illuminates the right hand verge. This 'low beam' pattern feature has been a world wide standard since the 1960's and gives a better sense of space, and makes signs and such easier to read. The MB intersection, turning beam and cornering features already work, but I felt the EU 642 settings were a bit brighter than our 640 setup. That about covers it for city streets.
Once above ~30mph/50kph the automatic high beam we have is changed to a variable beam intensity and coverage that is noticeably better as the street lighting becomes lower. This is the new part. As it road becomes dark the full beam power turns on in a wide full beam. As advertised by EU Mercedes Multibeam Youtube illustrations, I was driving with the full beam manually set (headlight switch full clockwise, dimming lever forward) and not a single oncoming car flashed their headlight to complain of blinding light. However, proceeding cars ahead of me are not blocked until the road becomes darker. They get blasted with light because the system does not have enough light contrast to know to block out the car ahead of you. So it worked just as a test, but would I would leave the headlight switch in Auto so it can function properly.
The fog lamp pattern is slightly dipped and again brighter and a little higher on the right hand side with 642 (EU) vs; 640 (US/Canada), Unexpectedly, last night I drove into 10m fog at about 1000 meters elevation and appreciated this improved pattern. So again, if you find yourself in fog a few times a month, changing the firmware is recommended.
Now, when driving on an un-lit street or road, the 642 EU firmware really comes into its own. The beam rises slightly and light intensity increases. Oncoming cars, highly reflective parked car tail lights, road signs are attenuated and sometimes blocked completely. The beam intensity varies with vehicle speed, throwing a brighter and brighter lite forward. In the presence of oncoming traffic it tones down slightly and starts masking oncoming traffic. It is interesting that this masking out of oncoming traffic is rarely noticeable, for the simple fact you are looking into their bright headlights (duh!). This fact explains why the MB Multibeam is not actual video, but illustrations that demonstrate the concept and its various features.
My experience with the EU 642 firmware ODBII modification is very positive and I recommend it for those who frequently drive at night in outlaying areas or routinely make inter-city trips. Vladimir has been doing firmware recoding for several years now and has a solid reputation.
I cannot add more than what Mike_S and LILBENZ230 described, fully agree.
I am attaching a video I took after I applied Vladimir solution.
I just installed Vladimir's update and drove on roads with no street lights. I did not notice any difference, but left my light switch in the auto position (with stalk forwards). As usual, the high beams dimmed automatically for oncoming traffic, and then swept outwards once cars passed. Are we supposed to leave the light switch in full clockwise position (high beams on all the time) for the EU lighting tricks to work?
Thanks for input.
UPDATE: I did not realize that I needed to use the center console rotary switch to select 642 activation yesterday, and only backed up the log file, so nothing actually changed! Installed correctly today, and will test tonight.

One thing I did learn from playing around on this test drive is that beam shaping only occurs when light switch is set to auto (the default position). When the switch is full clockwise, the high beams stay on all the time, irrespective of whether there is oncoming traffic. Makes sense to me because there may be times you want high beams on no matter what.
I learned about this option from this thread, and from comments posted here - thanks to everyone.
The title 'Multi-beam in Canada' is a bit misleading because all of this applies to US market as well.
Here's what you need to do:
1) turn on car (full on, but without starting engine) and wait about a minutefor command to fully boot (e.g wait for navigation, voice commands etc to load)
2) Insert the device into OBD socket - press firmly to ensure its correctly seated.
3) The script Save Backup to LOGFILE will be visible. Click on the command rotary dial on the console to activate; it takes less than a minute.
4) The screen will indicates when backup has finished, and instruct you to remove module.
5) Turn ignition on and off a couple of times, and then repeat steps 1 and 2 above
6) Turn the rotary dial of the command control on the center console and a new script will appear 'Activation SA628 On/Revert'
7) Click the command button to activate; it takes several minutes to run, but when its complete, it again instructs you to remove module.
Thats it. One very important thing (per Vladimir) is not to interrupt the process while an update is in progress. For the light activate it looks as though the process has stalled; it has not, just be patient and wait for it to be complete.
I tried several times. Twice following Vladimirs instructions that do not say to turn the car completely off between backup and activate, and twice following the instructions in this forum that say after backup turn ignition on and off a few times then wait a minute then move on to install. Each time all I got was an exception error
