Headlight wiring diagram help

[v8z4]

I’m trying to rewire/bridge the headlight and foglight circuits so that:

- Low beams on turns on fogs also (fogs on would NOT turn on low beams)
- With high beams on, the low beams/fogs would remain on

I had planned to just bridge the lows/fogs/highs with diodes appropriately placed, however looking at the wiring diagrams, it looks like the Lighting Switch Cluster directly feeds the headlights (low and high) rather than operating a relay. Is this correct or is there a headlight relay somewhere?

try checking with ncsexpert coding as bmw coding :

NSW_BEI_ABBLENDLICHT = Front fog lights simultaneously with low beams
NSW_BEI_FL/LH = Front fog lights simultaneously with high beams in FTP

Where would I find those?

You need to have ncsexpert software and look through the fsw_psw.man file

I finally found a good copy of NCSExpert and have the programs installed/running. However I'm not getting connection to the vehicle.


I'm trying to use my BMW Scanner Version 1.4.0 cable as the interface cable (since I already own it). Anyone use this cable with NCSExpert?

The cable works with the BMW Scanner software, so I'm trying to figure out if its an incompatability between the NCSExpert-cable or if I don't have something set up right with NCSExpert.

IF the cable is NOT compatible, what is a good (and cheap) cable to get?

checked my fsw_psw.man file and it has the following:

FL_UND_NSW_NICHT_GLEICHZ not active - Front fog lights not simultaneously with high beams
