Replace communication module

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. It sounds like you're dealing with a complex electrical issue in your XE. When a communication module fails, it can sometimes cause a cascade of issues in the network of modules, leading to multiple failure codes. Although a diagnostic scan usually reveals all current issues, sometimes, not all affected modules communicate their faults right away, especially if a primary communication module is down. Once the initial module was replaced, the system could start detecting other problems, as it can now connect to the network entirely. The mechanic's assessment seems reasonable, given the way electrical systems can behave. Still, it may be beneficial to get a second opinion, especially with a highly specialized vehicle like the XE. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
