The car may have a fault code logged in the ECU which is preventing the Preconditioning from working, on my car the pre conditioning didn't work before I had an airbag fault, the car went into the dealer to get the airbag fault repaired and when it came back the pre conditioning started working. I presume the dealer reset all the ECU fault codes when the airbag fault was repaired. This is a common ploy used by manufacturers to get you to take the car into a dealer to get a fault repaired on the pretext tha tthew issue is something else. EG 51 plate mondeo boot switch doesnt work when the side door lock is in fault. same kind of thing.
September 22, but what I'm saying is I don't think anything was wrong with the pre conditioning because nothing on the pre conditioning was repaired to get get it working. I think a fault logged in the ECU with something else was cleared which enabled the preconditioning to start working. My heating actually worked fine, just the pre conditioning didn't, they are both the same thing, so their couldn't of been a fault with the pre conditioning it was just disabled in the software program, which was enabled when another fault was cleared. Thats my theory anyway.
it was free as my car was within the warranty period, they did the bms and energy flow, but my preconditioning still doesn't work, not sure if you will have to pay to have that done out of warrenty.
Apologies for late response, I completely missed post. My first question is, why do you think the car needs the BMS update?
If the BMS update is required for a specific reason, make sure you state that rather than any solution numbers you may have seen on the internet.
When you book the car into the dealership, make sure you tell them that the "energy screen not displaying as per the handbook", a dealer can investigate and carry out any known solutions.
Happy to help out and again apologies for not seeing post earlier.
