Technical 2022 Ducato Full LED headlights

[Ian789]

I've ordered a 2022 LHD Ducato based campervan from. France. It's nicely specced including full LED headlights with LED DRLs.

Does anyone know if its possible to adjust these headlights for driving in the UK (so it passes the IVA??)

I've seen elsewhere that these LEDs have quite a flat beam and also seen mention of a 'neutral' beam pattern (whatever that means) but cant find a definitivec nswer to their adjustability for driving on the left ( or back again if on holiday in Europe).


Any help much appreciated.

Thanks

Ian

On 2019 (halogen + drl led) it was:
Byte 76: 20
Byte 134: 20
and worked properly with full led headlights, but with errors on dashboard for drl and signals(resolvable with 21w resistors)

I've changed to:
Byte 76: A8
Byte 134: A0
working properly, but still have errors on drl:
B1078-96
B1077-96
Component internal failure.

Can someone help us with custom proxy values from a 2021+ with full led headlights?

finally full working:

Byte 76: 28
Byte 134: 20

without any errors, please find bellow my proxy:

with or without resistors?

 

[vladandrei83]

For signals I have resistors. I'll try to take is down to check.

 

[nikosgrk]

Yes it will be better without resistors just with correct proxy

 

[vladandrei83]

I didn't find an option for front turn signal Led. I have just to choose between 21w and 27w. Same for mirrors: 5w or 16w. I tried also other proxy values, work ok just using resistors. I am ok using resistors. On 2019 I use 21w Osram resistors. +12v turn signal: left Blue/White, right Blue/Black. Fyi: for 2019 with alfaobd need to select x250 facelift BCM. For the rest of modules work with x290.

On Ducato 2017 full led headlights working properly after changing 2 bytes on positions 76 and 134 in MES.

First of all Ctrl+alt+c and backup all values (select all copy and paste in a notepad txt file)

Byte 76 - change value to A8
Byte 134 - change value to A0

Then run proxi alignment procedure.

Working properly with halogen + LED daylight headlights, same full led headlights.

Single difference is that for full led headlights need 21w resistors on the signals wires to not receive signal bulb warning.

I tried and no coding needed, they work straight out of the box!!!!!!!!

 

[nikosgrk]

I fully tested them. I can confirm that for the new ducato led headlights there is no need for resistors or programming. The are plug and play and they work straight out of the box in my 2015 fiat ducato.

 

[nikosgrk]

Just to clarify that daytime light turns off when turn signal is on.

 

[vladandrei83]

Please share your proxy here to interpret it. You didn't use resistors for signals?
