Installing 6C full LED oem headlights in a 6R.

[iichel]

It needs to be a bcm with the pr code for LED headlights. Its the so called Z code. The a b c etc doesn't matter that much. Or you can buy any 7E0 937 090x bcm and flash the correct eeprom parameters with vcp.

I.e I started out with 7e0 937 090 z4y. Now I have 7e0 937 090C with led and kessy parameters flashed with vcp. Works just as fine.

Thx iichel !!!

I will search for this bcm 7E0937090 z4y. Do you know if this bcm supports start/stop??
And is there additional wiring needed ?

All 7E0 BCM Max support start/stop system.

You have to look for a BCM 7E0937090 B /C /D with PR code 8IT

7E0937090 works with an internal (virtual) Gateway, so you must remove your external Gateway (forever) by transferring the communication wires (CAN, LIN) to the BCM connectors. You also have to transfer your current Instrument cluster CAN lines to the BCM.

I recommend that the software be at least B /C / or D, it will allow you other nice mods.

Nice ciclo !! Great info can you give me the topic ??

I found a few bcm with the correct part number, but I can’t find the so called PR code or the Z code ? Some of them didn’t even had a letter on the end...

I know this might be a stupid question....

This one ok ??

8IT = LED Headlights

iichel or firegrafik can help you with this matter, it depends on what you choose.

IMO the cheapest way is to buy this directly from Russia, Alexander know some guys who can change BCM's software to make support Full LED headlights.
I bought my second BCM (090C) from RoFIREmaN: https://www.drive2.com/users/rofireman/

BCM - 4500p
Parameterization - 800p.
Shipping costs - 1330р.

Probably now prices can be better, and BCM in version D is already available

The PR Code is not visible on the part, so buying a used BCM you would have to be sure that it comes from a car with Full LED headlights (Buying it e.g. on an allegro is almost impossible)

If you (or someone near you) have original VCP, you could take any BCM 7E0937090B/C/D new or used, and just change some parameters data in the BCM's EEPROM if it will be needed. In other case it is better to request it from someone who is able to take any BCM and provide that operations to ensure it will be surely compatible with LED headlights.

@firegrafik thx for your reply, munch appreciated.

An fortunately i don’t know any one that can do that

Can you pm me ?

[ciclo]

hmm ... you can pm him or anyone (you already have 10 posts)

Hi guys,

I found the bcm D (picture)

What to do now, wiring ? Coding ?
Removing CAN, wiring parking lights etc

[iichel]

My suggested plan of action:

1 prepare for BCM replacement
1a autoscan with old BCM
1b adapmap from old BCM, CAN gateway, battery monitor

2 Install the BCM
2a remove the old external CAN gateway
2b wire CAN networks to the BCM (powertrain, diagnostics, instrument cluster)
2c wire 58d (1 wire from BCM to dimmer) + vcds coding
2d restore all the codings and adaptations to BCM, gateway, battery monitor
2e (if necessary) make adjustments to the BCM eeprom with VCP
2f adapt remotes

3 install LED headlights
3a install all the wirings necessary + adapters from 10 pin to 14 pin
3b do all the codings for LED headlights with LED DRL
3c install AFS
3d replace dimmer with headlight range regulation to dimmer only
