If I have not used my car for say 3 days, when I go to start the car an error is reported that the 48v system is low but will recharge whilst driving. I have seen this many times with no impact on the car.
Recently I had left my car for 2 weeks and when I came to start the car the same error was reported along with many others ( 48v charge system fail, Brake boost problem, Evap problem, Dealer Service Required and many more.)
Surprisingly after driving for 5 minutes all of these errors disappeared, I used an OBDeleven device to see what faults had been recorded but none were present.
Anyone else had any issues like this?
