H4 to H7 Coding

[dubber36]

Anyone know if it’s possible to do this with LED headlights.

Factory LEDs already do this.

Just watch the last min if your looking for the carista guide.

Now possible with carista beta version.
I've just done this today on my h7's

Any one tell me how to actually get Carista beta ?!! I’ve done what the web tells me and downloaded the TestFlight thing but I have no code to redeem ! Confused !

 

[Minimucks]

Did you apply to become a tester for the Beta version?
It's wasn't an instant upgrade for mine. Seem to remember having to wait a few hours.

There is no code needed once accepted.

 

[nickg77]

Thanks mate, couldn’t see a way to apply just sent debug data etc

 

[Minimucks]

If you've sent the debug data you should be good to go I think. Try again and see what happens. It always does a long scan the first time for each vehicle.

If you have standard H4s fitted I would not use this mode as already stated they get really really very hot and go pop. This could damage the inside of your lights and be a costly repair. I turned it off after advice from members on here,

Sorry, I have tried a search but couldn't see how you code the dipped beam to stay on with head beam with VCDS. Could someone kindly point me in the right direction?

Thanks in advance.

Thanks @mmi

Thanks @mmi that worked perfectly. I also turned of DRL's whilst handbrake is applied.

I also made some other changes, including DRL's 'winking' with indicators. This seems to turn of the DRL on the side indicating but doesn't 'wink'. Is this the case? I tried it without and the DRL just stays on.

I have also tried a few times to code auto locking at 15kph but this doesn't seem to happen for me. Anyone know what I maybe doing wrong?

Coding for auto locking pic.

Not exactly sure what you did/tried. Which byte/bit?

I'm afraid you stumbled across a "known" peculiarity of T6 BCM - coding changes of these locking functions don't always work.
More details here (Sebastian's post) --> Transporter 2018 + HEX V2

Anyways, have you tried disconnecting starter battery after coding change? It seemed to do the trick for me - "pending" coding changes finally came true.

Thanks @mmi - I haven’t disconnected for this reason but I have fitted a new one since I first tried.

 

[BrenR]

Funny enough I haven’t managed to get the audio confirmation to work either as per your link.

You do have factory alarm/sounder?

Yes byte 23 bit 7- thanks, seems to be working fine.

Yes according to the build paperwork.
