Absolutely you're right! I'm not questioning the standard of work previously done to the car at all, I just find it a bit hard to understand why this other garage didn't spend the few minutes after full alignment to re-calibrate the sensor!

It's very obvious that after the previous work done that these sensors were re-calibrated. I guess it's just down to the garage or knowlegde of the mechanic. But definitely I had no problem going back to the garage to have them fix it, I just wanted to do some research to make sure I knew what the problem was so that they will fix it!

Thanks for all the help and replies anyway!
