BMW X1 21 Plate Tripping House Circuit Board

[Stuartmcm]

Morning!

Looking for some support before I get down to BMW.

Car - x1 hybrid 21 plate 30k miles

I bought my car from Cinch 2 months ago. 1 month down I was plugging it in via a 3 pin plug through the window with now issues. All of a sudden this started tripping the circuit breaker in the house. Nothing changed, no damage to the charger or plug. After I put the charger into the BMW after 1 second it pushes a message back via the charger shutting down the house power.

I’ve had a local electrician round to check various other parts of the house and he said it’s likely the car. Has anybody had any issues or got any tips dealing with this on their hybrid?

Thanks
