Hi and welcome to the forum. From what you wrote, I guess that you replaced the CEM module. Even if the part number is the same, there are a few programmable options, such as front fog lights, rear wiper, DRLs on/off. So my guess would be that the CEM you got, does not have the front fog lights enabled. It can very easily be programmed with the Volvo DICE diagnostic tool. If you still have your old CEM by any chance, you can lug it in and see if the front fog lights are still working. If they do, then it will be 100% the CEM not having the front fog lights enabled
