First try to tab the box with screwdriver while slowly lifting at the same time, very inportant. I repared 7 boxes the last 2 years, they had all strange errors caused by the minirelais inside, if you lift and it falls you get a lifting error, the same for driving, the same for steering, you get my point!!! I can sent same picture,s for the relais, cost a dime instead of a new controller for 2700 euro,s!!!
