My wife's car battery has gone flat an several occasions with the kids leaving the lights on. So far I have managed to start via jump leads - however not today. I have had to bump start the car and wonder (as I have seen mentioned on forums) that I have now damaged the catalytic converter. If I have is it something I can get checked out ? It's just passed it's mot (another long story here - to follow some day) and I wonder if in a year it will fail because of my actions today.
