Hi all I am new here so hello to everyone 

I just have a question 

On Sunday my car had a blip like thing happen the lights went out on dash while driving only for  a second 

But after that I have no power windows or mirrors no dash lights or high beam

So I stopped called rac who found fault to be the frm

So the car is parked at work waiting for me to get it fixed

Anyway yesterday I received a recall letter from bmw about battery cable and it says that it causes blips with power

I am wondering I'd this could have caused the failure of the frm 

Has anyone else had a recall letter and had any similar problems 

I no if it is not that its gonna cost me a small fortune to fix

Thank you
