@Metsavend What excactly is your expectation after changing the CEM? The CEM of the V40 seems to be the same for all model years 2012-2019. Vdash should be able clone these to new or virginized CEMs if you have the write protection and IMMO pins of your old module.

Retrofitting keyless entry should be possible, but it's a hell of a job. Your car is most probably not prewired for this, so you have to install all the missing wiring. Also all the antennas needed and the door handles. then you can either install a used compatible module after extracting the KVM IMMO pin on the bench from it and adding this pin to Vdash. And hope that there are no other VIN specific codings needed to use it in your car. You will just need to change the CEM configuration with Vdash and should than be able to program keyless fobs to your car. But I cannot guarantee that this will work.

Or you have to talk to a Volvo dealer if he orders the configuration changes needed and also the software packages to programm a brand new KVM module and keyfobs to you car. This is most probably not possible with a subscription for private users as you need to be SERMI or NASTF VSP registered for IMMO/Key coding with VIDA. There might be independent Volvo repair shops with the required license and VIDA subscription level, but you will pay the same or even more than at an official dealer.

@Claudio_DU The language has nothing to do with other region settings. What options do you see when you click on the DIM after connecting Vdash?

@Mustapha You will need to pay for all configuration changes that can't be done with diagnostics commands. This means if you click on a specific module after connecting Vdash and are able to change something that way, it's for free. If you have to use the "advanced configuration" or "language" menu, you have to pay or buy a subscription. Depending on what options you want to change in total, it might be better to buy a FLAT CONFIG subscription which costs 69 Euros for the first year and includes all configuration changes that are possible. Otherwise single configuration changes usually cost between 19 and 99 Euros depending on what you want to change.

@Mustapha I currently don't have the time and patience to investgate this further, but if your car has a VIN where the last 6 digits are higher than 614383 it should be possible to enable automatic headlights. But you will need to do changes to the electronics besides changing the light switch. Turning the fog lights into DLRs is not possible. Adding a switch with pn 31318937 and a separate switch for the front fog lights might work, but it's possible that you get a DTC because the DLRs are missing. Get yourself a copy of VIDA and EWD(wiring diagrams) to do your own researches. VIDA can be found here in this forum. EWD is available here

The pin decoding sets the car in programming mode. This means the car is completely unusable. Everything goes dark and the doors can't be locked. You will also need to attach a powerfull charger while decoding. Decoding with Vdash can take up to 24 hours, but usually it shouldn't last longer than 8 hours. At least with a Super J2534 adapter. Other adapters will be slower. Of course you can pause the decoding at any time. You can also rent or buy a VDD from D5T5. Decoding via VDD shouldn't take longer than 30 minutes on most V50s.

@Bartas222 the factory configuration for iTPMS looks like this.

After changing any parameters with Vdash you have to shut down the car and lock it for at least 20 minutes to make sure the changes get properly applied.
The tyre monitor should be visible as seperate menu under "My Car".

@Mustapha What options do you have under "front fog lights function"?

@Jovatech Vdash won't be useful for this, as it lacks the needed diagnostic commands for your car. You will need VIDA for this.
You basically disconnect the battery, change the CCM, reconnect the battery, and then connect VIDA and navigate to diagnostics/vehicle communication/CCM/advanced and use the 2. option. Not sure what it's called in english. Something like self adjustment of flap motor/actuator stop.
That's it.
If your old CCM is still communicating, you can clone it Vdash, but as you want to install a used one, the software for it to operate should already be present in the replacement.

@sawcar you will need to source the correct control module variants for the EU headlights. Volvo uses variant specific control modules for EU, US, UK and so on. US modules won't work on EU headlights.

@0xballer too bad.

@HoodedLime I didn't mean for cracking, but for coding/programming your car. The DICE should still work, but is too slow and therefore risky to use.

@HoodedLime Good luck!
200keys/s is actually okay for a DICE. But on a SPA you should definitely use a Super J2534 or a VOE adapter and not a DICE.

@HoodedLime Not a helpful answer, I know, but 200 keys/s on a P3 are a clear indicator that your setup is slow or has some sort of bottleneck. 450-500 keys/s on a P3 are possible on good setups. Atleast with P3tool and P3Dx. Not sure about Vdash as I'm not using that for P3 cracking anymore.

@0xballer You might want to get in touch with Obbe tuning https://www.obbetuning.nl/
This is the guy who makes all tunes for D5T5. Maybe he can help you. But I'm not sure if the tune is your problem.
Just out of curiosity. Have you already checked/cleaned your throttle body, MAF and MAP sensors? If those are blocked/dirty with lots of soot it's possible that you will get misleading DTCs like too high or too low flow. Also MAF related error codes can be triggered if these sensors are too dirty. It's also possible that one or more injector is worn out.
On some engines the EGR still has to be clean and working, even if it's "deactivated" in the map. I'm not sure about your engine with this.
What adapter are you using to flash the tunes? Anything else than a good DICE clone with M32C chipset or a Super J2534/Mongoose JLR Pro with Atmel chipset is clearly not recommended and might also be a source for your problem. Same goes for the charger/battery tender which has to be connected to the car while flashing any software. But I think that's not really the cause of your problem.
And be aware that your ECM can only be programmed/flashed around 10-20 times before the flash memory might start to go bad and will irreversibly brick your ECM. V50 ECMs are really not designed for regular software updates.

@Qube Moin
Um deinen Wagen einzudeutschen musst du den CEM pin dekodieren und einige Regional Parameter im CEM ändern. Das ganze solltest du vorm Umbau machen. Und du musst ein LCD DIM mit weißer Rückseite (Gen. 1) und passend zu deinem Getriebe verbauen, die DIMs mit schwarzer Rückseite sind nicht kompatibel mit deinem Wagen. Zwei zusätzliche CAN Leitungen von der OBD Buchse zum DIM musst du auch noch ziehen. Bei deinem Baujahr musst du auch mit einigen Einschränkungen leben. Das Lenkradschloss muss evtl. per Vdash deaktiviert werden, falls du eine entsprechende Fehlermeldung kriegst. DSTC kann nicht deaktiviert werden. Service zurückstellen und Uhr stellen geht nur per Vdash. Power/Eco Anzeige funktioniert mangels Daten vom Motorsteuergerät nicht.
Alles wichtige gibt's hier
Den TÜV interessiert der Umbau nicht solange die Kilometer nicht manipuliert werden, was mit Vdash eh nicht möglich ist. Der Original Kilometerstand wird beim Umbau vom Originaltacho bzw. CEM übernommen.

@Usturmaca

@Bigv Do you have a check engine light now? This would mean there is another problem with your engine. Checksum errors don't trigger the CEL and can be ignored as long as the engine starts and runs without problems.
I can't help you with VIDA. Subscriptions for legit VIDA are only available for private users in the US, while I live in germany. Cracked offline versions like VIDA2014D are not able to do software reloads. Your tuner should have made a backup of your original software and should be able to restore it.
Reverting to stock software would also require to remove the blanking plate as the EGR would be reactivated.

@Bigv Did you just blank the EGR, or did you install a remap/tune with EGR off? Remaps/tunes will always trigger checksum DTCs in the CEM and ECM, which you can only get rid off by reverting back to the original, untampered Volvo Software of the ECM. Or by performing a software reload for the ECM with VIDA. There is no other way to fix this.

Thanks for sharing this.
My personal recommendation is to use a dedicated computer with as less as possible 3rd party software installed. Especially no 3rd party antivirus, security, firewall and VPN software. As those clearly interfere with the vehicle communication. The lesser useless running background processes, the better.
Using your cluttered everyday machine for stuff like Vdash or VIDA is always a bad idea.
And Vdash most probably has some sort of anti tampering routines. It most likely detects software like Wireshark or the Npcap drivers and crashes on purpose, to prevent reverse engineering of how Vdash works.

@SOpEL Volvo lists specific modules for specific headlight variants. So it's not only a matter of software. If you can open this link you will find several variants of headlights, and several different modules which are only compatible with specific headlight variants. You will need to source modules that are compatible with your headlights.

@0xballer create a support ticket here if you have problems with tunes from D5T5.
