@JarekV740 The code is for a too high resistance between the steering wheel airbag and the SRS module, and has nothing to do with fixing the SRS software. Was the clock spring/SAS replaced together with airbag in the steering wheel? This part usually gets damaged when the airbag is deployed. Also check all connectors between the SRS module and the airbag.

@RobinPe What happened to the car before the ECM went out? And what kind of diagnostics have been done to come to the conclusion that the ECM must be damaged? As this is really unlikely to be the problem here. Did you check the connectors for water ingress/corrosion? Did you check continuity/grounds/voltage supply/fuses/relais towards the ECM and CEM?
Syncing a used ECM from another car is impossible via OBD/software as the VIN specific, unique security/encryption pins for ECM and IMMO data can't be overwritten once they are programmed to a new unit at the factory or dealer. At least that is my current state of information.
Swapping the flash memory of your old ECM to another one on the bench would be required, hoping it isn't corrupted or damaged. Or you need to "virginize" the ECM from the donor car and than clone the software from your old ECM, or perform a software reload with VIDA.
Try to contact some local specialist for ecu repairs and ask them if they know this ECM, and if they can help you in any way if you really think the ECM is dead.

@Oleg-Alaska You need the VGM pin to delete codes and clear the crash data on this car. Cracking this pin is impossible. An official VIDA subscription and knowledge how to get this pin while loading software to the car is required. Try to find a Vdash pro partner here https://d5t5.com/partners

@johnzero 5 cylinder Diesel = ECM pin reading on the bench required.

@smithnumbertwojunk In general for any petrol P2, you simply unplug the old one and plug in the new PEM. Done. No coding needed.

@smithnumbertwojunk Please specify the car. Which model, model year, engine code?

@Caerbannog13 Hi there. Just as a tip. There is a mobile phone app called V-Tool https://v-tool.app/ which could be considered a VIDA light version. It reads and deletes codes from all ecus and allows to activated service functions like service reset, BMS reset, EPB service and so on. You just need a compatible Bluetooth OBD-adapter. As you have VIDA, you can look up the detailed descriptions of all error codes, which are shown in the VIDA format btw, and also the associated fault traces whenever you have a problem.

@Mustapha Automatic headlights is only available from factory for cars which have Xenon/ABL headlights. This automatically means no front fog lights. If your car has halogens and front fog lights, this means no automatic headlights without findung an own solution how to switch the fog lights on/off. Xenon/ABL+front fog lights is not possible with any configuration change/factory parts.

@Mustapha As the complete switching on/off by sunlight sensor is done by the LSM (light switch module) you might just try to find a used switch that has the same buttons and regulators as the current switch plus the "A" positon and install that. There might be no configuration change needed at all. Just another switch.

@Ossian "Soon"
There is no fixed date yet, but it is planned for the first half of this year. This is my current state of information.

@Mustapha You will need different light switch that looks like this for example

There are 3 different types of this switch.

Headlights on in Pos.0 is something different. In some countries it's a legal requirement to drive with headlights on all the time. The configuration for "headlights on in Pos.0" will result in the headlights turn on in all switch positions whenever the engine is running. The light sensor has nothing to do with this. You just won't be able to use the highbeam in Pos. 0 and parking light, and you will drive around with headlights on all the time.

Automatic headlights on/off is meant for cars model year 2011/2012 with Xenons/ABLs and installed daylight running lights, and works by switching the light switch to Pos. "A" in combination with the sunlight sensor. If this works on cars without DRLs and with Halogens is unknown to me.

What options do see when you open "Car configuration" -> "Show old configurator" -> "Lighting" -> "Dipped Beam"

@Ossian that is correct, you have a version 3x dongle with serial number 763 and FW 0.95.79. This FW seems to be the latest "stable" version that is issued out for everybody. My 1x dongle has the same FW. If you want a newer FW, you need the open a support ticket. Do this while the opening hours of D5T5. Mon-Fri 9:00 - 16:00 - Central Europe time zone.
As there will be an new VDD app soon, you might want to wait if you don't have serious issues.

The FW version is shown in the VDD app in the settings tab.
You can't update the firmware yourself. Updates should be installed automatically, but this never really worked for me. Contact the support if you think your FW is outdated or missing a feature that was added with newer versions.

@pamie849 that sums it up. The official description doesn't mention anything about that. https://d5t5.com/article/scu-pair

@johnzero There should be an configuration option somewhere in the light or region settings to run the DRL's dimmed with headlights on, but I'm not sure if the V40 supports this, even if the configuration is available. You can look this up without having the CEM pin. Open the advanced configuration menu and look around. You might need to switch to the classic menu style.

@pamie849 I'm not sure about refund. D5T5 has quite strikt rules about that. https://d5t5.com/article/refundace But try it and maybe mention that needing the KVM IMMO PIN is not clearly written anywhere on their website and in Vdash. Also include a link to this forum thread. Create the support ticket during their opening hours. Mon-Fri 9:00 - 16:00 - Central Europe time zone

@Mustapha Paypal is available, but costs a little extra fee.
Automatic light needs the sunlight sensor in the middle of the dash board

and maybe also a different light switch. You can check if activating this option is available for your car by checking the advanced configuration options, but before you actually change that option, you need to check that all hardware required is installed in your car. Vdash doesn't have an automatic check for this.

@Mustapha Changing the language costs between 0 and 150 Euros, depending on the car, language and if it requires just sending a simple diagnostic command, or if loading new software to the car is needed. See the pricelist here https://d5t5.com/article/subscription-types-prices
On your car it's loading new software.
If 39 Euros is shown, it's the correct price for your car. Depending on the payment method, additional service charges might be added.
Payment can be done through Vdash. Just buy the required Credits by clicking on the money symbol in the top right corner.

@johnzero Decoding with the VDD is a standalone process, no laptop/DICE needed. When it is successful, the pin will be added to the Vdash database and you can start using Vdash on the car.
The car can't be used or locked while decoding. It will enter programming mode after you start the decode process. This means the car is clicking here and there, and then goes completely dead. Never start the decode when the engine is running!!!
The decode can be started without a key in the car. You should still unlock to be able to open the hood/disconnect the battery if the process crashes.
As the decoding might take up to 8 hours with the VDD, you should indeed connect a charger while decoding. The process can of course be paused and continued later. You might also want to use an OBD Extender cable to place the dongle behind the windshield for better mobile network signal.
BTW: I have never been able to successful perform a decode with my VDD, because it was always aborting/crashing after around 30-120 seconds with the car not fully waking up from programming mode afterwards. The support was never able to figure out why, so I bit the bullet and decoded the classic way.
