Hi.

I'm the owner of a workshop here in Mexico and I'm having some issues with the FRM of various Minis, all of them 2007, 2008 and 2009.

the problem comes when we work in a car that will be there for a long time, we take out the battery, we recharge it and reinstall it on the car, but we we reinstall the battery, it goes the FRM code that is blown.

Do you know why this is happening?

thanks for your help
