A good sign of a regulator that is starting to go, is an intermittant gas supply when your bottle is quite full. For what a regulator and a bit of pipe costs, it's worth just replaceing anyway every 3 or 4 years.
...Just to add to this point ... There are a number of different gas regulators on the market that can vary a few Euros in price. I have found that it is worth paying a little extra to get the better quality ones, because they don't tend to suffer from having a plunger that sticks quite as often as the cheapo ones do.
