Ducato x290 LED DRL headlight retrofit.

[Ryan]

Hi can anyone please help me with retrofitting these lights, I have downloaded multi scan the registered paid version, I have the elm cable and the yellow adapter but cannot connect for love nor money, or is anyone local to Cheshire that can change these bytes for me? Obviously will pay

What is your ELM device and where did you get it from?

There are many ELM devices that just don't work on Fiats.

Hi
Has anyone had any success in changing there drl’s from the bulb type to the led type (changing the full head lights)
I’ve had my fiat Ducato camper-van since 2022 (the van is a 2022 model) and I’ve had no such luck, I’m happy to pay someone to do this or take me through the procedure.
Thanks Stevie

If it is just the DRL bulbs then have you tried just replacing them? No need to change the whole lamp unit. MES / other will also not be required.

And don't be confused by so called CAN Bulbs/LEDs. There are no such beasts. What they are really saying is that the LED replacement should not cause a lamp failure warning because it incorporates an additional load resistor to make it look like a normal bulb.

Hi
Sorry I may have not explained myself correctly, my van came from the factory with the halogen DRL’s which are very common in a fiat Ducato, these headlights are the more inexpensive headlights and they don’t look as good. There is an upgrade headlight from fiat that has LED DRL’s which is built into the bottom of the headlight but these lights will not work with out the body control module being altered. I have found a company in Germany that can do the programming but it’s a bit of a drive just to get this work carried out.
So if anyone know a person or a dealer that can carry out this work on a series 8 fiat Ducato I’m happy to pay them
Thanks Stevie

OK. I understand. I was trying to say that if you don't want to replace the whole light cluster which would be expensive you could look and just replacing the halogen DRLs (Daylight Running Lights) bulbs with LEDs ones and leave the Headlamps/Driving Lamps as halogen ones.

If replacing the whole unit then MES can probably program the correct Proxy data but I don't know what bytes would needed to be changed and to what values.

Hopefully somebody here can advise.
