yeah I have also about it on bmwcoding but nobody actually has measured the voltage.
Fact is that for increasing the voltage you need a different technology then for lowering it. Its a big difference. BMW never intended to increase the voltage so why would it then be possible by coding ?

 

Hi RoberMc i have fitted the lights and have wired only right light wire to lm module

i have also added the code to the VO and done fa write on cas and lm

i have coded it to the car by using expert profile by doing sg codin on lm module

when i turn on the lights the fog light comes on low power on its own

when i press the brake pedal the rods light up but not that bright and so does the inner bulb the outside bulb does light up

any idea whats wrong here i havnt changed any other wires around yet

the reverse light works

when i turn on the rear fog that goes brighter

but no rods lights up with lights on and brakes off

thaanks

 

i been studying the retro fit pdf and the wiring has changed in the 2007 and 2008 pdf file as there was errors in the 2007 bmw stopped selling this retrofit wiring kit

the wiring i brought was wired up exact how the 2007 pdf shows which was the one with the error

i changed the wires on both left and right wiring on pin 4 and pin 6 around. as this is how the retrofit wiring should have came as shown in the 2008 pdf and il test again tomorrow

 

Thanks for the reply I think it's caused by wiring as it seems its wired wrong

I did check the code was added into the vo and stayed there in cas didn't check it in lm il do that tomorrow

My expert profile is good as I have been doing quite abit coding and it does reset back to default without man file

Just to confirm when I do fa write to cas and then lm that copy's all the vo and vin to lm?

These were the functions that didn't work on front headlights inner ae rings , no main beam flasher

 

hi thanks for all your help so far RoberMc mate you been great

all the back lights are working i left the wires to the lm as they only turn on the inner brake bulbs

on the front the only problem i have is the inner rings are not working

i have after xenons fitted they work fine as before

just the inner rings not lighting up i did notice they light up when i brake for some reason my headlights are the standard halogen with after market xenon

heres trc files

I forgot to mention the front flashers are not working too high beam

 

In that link there are two trace files please check again

 

just to confirm onr trace is the lm1 with every thing original connected from car

second one of the lm2 coded to car with +mueb added to fa and all back lights working

but faults on front ones the inner angel eye rings dont light up when turned on
the light up when i press the brake pedal?

and the main beam flasher doesnt work

do you want me to remove +mueb off from the vo and reset cas and lm and then send trc?


thanks for your help buddy

 

must of copied a wrong one by mistake il do it again sorry for the confusion

how shall i get you the lm2 trace with working pre lci lights would that we done by removing the code from VO and resetting lm2 with expert profile?

LM2 trace do you want the one with the FA code added to Vo too thanks
