Hello, I have a 2016 Cadillac ELR with DTC P1E00. The car drives fine except every now and then the check engine light comes on to show the same persistent DTC. When the check engine light is on I am unable to charge the vehicle, and would need to clear the code via a OBD2. Now, I took the vehicle to Cadillac and a technician told me the issue is because of a failing part, 24051831. This part has been discontinued by GM and buying one new is near impossible. However, an older model part, 20997056, is readily sold in eBay and other stores. Would this older model part work with my vehicle?
