How does my Volkswagen Golf's stop/start system work with a turbocharger which needs cooling?
The 'start/stop' system on my new Volkswagen Golf TSI is operating very smoothly and presumably contributing to its relatively good urban fuel consumption. However, I recall some discussion about the risk of turbocharger damage if an engine is switched off immediately following a high speed run. Unless I take action to over-ride the start/stop system I realise that this situation will occur, for example, at traffic lights on a motorway slip road. Should I be concerned about it?

Usually these systems have a temperature sensor that prevents the stop/start stopping the engine if the turbo is too hot, if the ambient temperature is too low, if the DPF is regenerating and, of course, if there is not enough charge in the battery.
