31423316 has been confirmed by a befriended volvo mechanic. So that should be correct. Browsing used parts the one that ends on 15 are found on vehicles without, and the one ending on 16 on with acc

This other article also states the difference in BCM for adaptive cruise on the V40 https://www.drive2.ru/l/696000482182706910/

Every article I've read about retrofitting adaptive cruise to the V40 stated that there is a difference in the BCM between the models, so changing over the EEPROM for the vehicles data, or reading the original one and writing the data to the new one is needed.

In my case the car is fitted with partnumber 31423315. BCM 31423316 is fysically different from the first one mentioned as can be seen here https://www.drive2.ru/l/700921346472808546/

Hi all,

After installing the FSM and FLR on my V40, driving for a while to make sure everything is working as it should, I'm now starting to go further with the ACC retrofit.

New brakebooster and BCM are already in my posession, yet still have to start mounting them. I'm aware that on the V40 this project isn't as straight forward as it is on other P3 models, because of the BCM and data on the EEPROM that needs to be transferred.

Do I really need to swap the EEPROM from my current one to the donor BCM, or read and write the data over between the 2 units, or will the BCM clone function inside VDASH do the same without needing to opening up the BCM?

An VOE cable is only for vehicles on the SPA and CMA platform.

Your S80 is on the P3 platform, therefore an original (of cloned) DiCE or Super J2534 is needed for a connection

Figured out the issue. I failed to notice the lead going into the CEM. This fixed the issue I had.

Next up, what would be the correct settings for a 2018 V40 to apply for the LDW?
Do I activate the LDW with sound warning, or is the One line tracking the correct one?

Hi all! I'm having a little bit of a pickle with retrofitting an FSM to my 2018 V40.

After connecting everything and making sure I'm splicing in the correct spots for the CAN bus, the FSM isn't communicating. In VDash it's showing up red, as is the FLR, in other software it's just grayed out.

The used FSM for this project is from a used model (31660982, dealer checked for compatibility on my vehicle).

When checking connections between the FSM plug and CVM plug both CAN terminals, the ground terminals and the power terminal are coming up as a closed circuit. But somehow, there is no communication possible between the car and the FSM. Trying to learn the FSM to the CEM using VDash resulted in an error.

Does someone know where to look next in trying to complete this retrofit?

Thanks in advance
