Yea, I got you. Discovering the "hack" with empty battery on the road is no fun.I just read your post on disabling the relay. That's cool if you are in control. It's a big problem when you are presented with a dashboard full of errors and nothing in the traction battery. The first time (2016) it prevented the ICE from starting - as your hack does. It took me a week to sort it. OBD was no help. The local dealer was no help either. The second time (Last year), the other relay totally disabled the car. No ready status and no EV driving possible. That happened at the M40 services near Oxford. Not a good place to break down. Fortunately I had a spare relay and was on my way within 15 minutes as I knew what to look for. I still carry a spare relay. These relays caused the only breakdowns I have had in 10 years ownership.
BTW In Canada there is an recall for that malfunctioning relay.
