Ford Focus 2012:

...

I was interested to read in your column recently about another Ford Focus owner who was experiencing a clunking noise coming from the engine as I too have a 2012 Focus and have the same noise. My dealer let me drive another and it was exactly the same. It was explained to me that it was the computer resetting the ABS each time it was stopped and restarted. I don't accept that, but I'm curious to find out what two parts in a computer come together to make this noise. Being the same engine in different Volvo and Mazda models, do they all make the same noise and why?

The noise is not coming from the computer, that's for sure. I've heard explanations before that it's the ABS braking system self-checking as you take off after restarting the car, but I can't accept that either. It only happens on some cars and all cars basically use the same ABS system, so that explanation doesn't stack up.
