Carlos ,
next (6)bit is responsible for brightness when lights are off as is possible
there more settiings
(5) bit is controlled in 16 steps from 0-F that's corespond rethrostage settings
finding settings howto separate controll NAC and cockpit

> 764: 664
22010E [/ CODE]
Then put the same data on your NAC:
[CODE]> 764: 664
: D91C: 03: 03
2E010EXXXXXXXXXXXXXXXXXX [/ CODE]
Where XXXXXXXXXXXXXXXXXX is the previously read zone.
Did you try a 308 calibration? Since it is the same screen it should work [/ QUOTE]

and you need write |FMUX to you unit from c4 calib to get it working
I send you string to write

nearly Done
Handbrake is on pin 5 of cirroco and is working@RuLe @hangway2 thanks for your answer
To summarize in order to make to change from original cluster to cirocco, I need:
A 3008 cirocco (9810394480)
- Are other part number also Ok?
- Is there any thing to make sure before buying? like taking it from a car that use the same fuel (petrol/diesel) or gearbox (manual/auto)
To connect the cluster you just need to connect:
- LVDS cable to 2nd NAC output
- 4 wire (CAN & power) on 18 pin connector:
You can do it either by repining the original connector 18pin or making a male/female adapter like did @RuLe
By the way I found on aliexpress the 18 pin male and female connector:

When digging in SEDRE for my car I found that I have at least 3 other wires connected to the 18 pin connector (I did not disassembly my cluster to count the wire):
- Wire 4425 on pin 9: commande voyant push frein de station électrique --> light on the hand brake switch (my car has electronic handbrake)
- Wire 7855 on pin 8: commande voyant push contrôle de stabilité --> ESP light on the switch
- Wire 7850 on pin 3: commande push contrôle trajectoire ESP --> ESP switch
So like @hangway2 says ESP switch will not work.
I guess @marcins is working with an arduino to send/listen CAN messages in order to deactivate ESP and to on/off the ESP light.
Does any of you have electronic handbrake? Looking at the schematic it is clear that handbrake light on the switch will not work anymore (but it should work anyway on the cirocco)
Regarding car mileage, I understood that car mileage is stored in ECU, cluster (and maybe BSI?)
If any of theses values don't match, the highest one will be stored every where.
So when switching to cirocco I should make sure it has lower mileage than my car.
Is it correct?
- Is there any way of reading the cirocco mileage before connecting it to the car? (just powering it up? or maybe by sending some CAN frame with an arduino?)
- Is there any way to change the cirocco mileage? (to make it lower than my car)
My car is only 13 000km so it might be difficult to find a cirocco with lower mileage.
Regarding telecoding for the cirocco, is there any setting to change in BSI or other ECU's?
Can all the telecodding of cirocco done with arduino NAC/cirocco software?
I found many messages complaining about dim issue.
Is it just a problem of finding the correct cirocco/NAC config?
@hangway2 :
What is the part you use for your cluster integration? It look like it is made for your dashboard?
Maybe as your car is LATAM version it is the C4 oem cluster? In europe/russia/china the cluster have 3 round shape so their is no way of reusing it for cirocco.
@marcins,
I see you also have an OBD gauge, which model is it?
I use an OBD x50 pro from aliexpress to display rpm (as oem rpm meter is terrible) and water temperature (Ds4/C4 does not have any temperature gauge, a shame for a 200HP car..)
But my obd gauge have some lag in the display of rpm.
Do you have plans to make an Arduino display that read sensor directly from the CAN and not the OBD2 protocol?
It should allow displaying more sensors than allowed by obd2 protocol without any lag issue.
In my case I would be interested by displaying oil level at engine start (real level, not just OK/NOK message like cluster does) and also tyre pressure/temperature (my car has tpms, pressure/temperature values are available in diagbox but the cluster just display OK, not actual values)
In theory it should be possible (arduino, + can shield + small lcd display), but it is far beyond my programming skills.
For cirocco milage u can reprogram eeprom, but u need xprog or upa and u have to read eeprom, modify milage and after write new milage.@RuLe @hangway2 thanks for your answer
